Energy Curable Inks And Other Compositions Incorporating Surface Modified, Nanometer-Sized Particles

US Patent:
6467897, Oct 22, 2002
Filed:
Jan 8, 2001
Appl. No.:
09/756303
Inventors:
Dong Wu - Woodbury MN
Brant U. Kolb - Afton MN
Kevin M. Eliason - Forest Lake MN
Kanta Kumar - Maplewood MN
Jennifer L. Lee - Eagan MN
Bruce A. Nerad - Oakdale MN
Jessica L. Voss - New Brighton MN
Caroline M. Ylitalo - Stillwater MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B41J 201
US Classification:
347102
Abstract:
Compositions that incorporate relates to compositions that incorporate surface modified, nanometer sized, inorganic oxide particles into energy curable fluids. The surface modification aspect allows the compatibility between the particles and fluid to be controllably adjusted to achieve a wide range of rheological characteristics. For printing, preferred compositions have favorable dot gain and thickness build up. When the composition is cured, the presence of the particles also helps improve physical properties such as hardness, modulus, abrasion resistance, refractive index, and the like. The compositions are particularly well-suited for forming printed, radiation cured features on substrates such as paper, signs, walkways, roadways, motor vehicles, boats, aircraft, furniture, equipment, and the like.

Optically Transmissive Microembossed Receptor Media

US Patent:
6521325, Feb 18, 2003
Filed:
May 31, 2000
Appl. No.:
09/583294
Inventors:
Lori P. Engle - Little Canada MN
Robert T. Fehr - St. Paul MN
Patrick R. Fleming - Lake Elmo MN
Alan G. Miller - Austin TX
Todd R. Williams - Lake Elmo MN
Caroline M. Ylitalo - Stillwater MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B32B 300
US Classification:
428195, 428205, 428207, 428211, 428212, 428213, 428500
Abstract:
A receptor medium with a sheet having an optically transmissive microembossed imaging surface as one major surface thereof. The receptor medium can receive jettable materials, which include inks, adhesives, biological fluids, chemical assay reagents, particulate dispersions, waxes, and combinations thereof. The microembossed medium unexpectedly solves such common inkjet printing problems as feathering, banding, and mudcracking in inkjet printing systems by controlling how an inkjet drop contacts and dries on an inkjet receptor medium and also Moire effects but also provides sufficient optical transmissivity to be useful as overhead transparency media, backlit signage, and the like. Clear lines of demarcation between adjoining colors of a pigmented inkjet image graphic can be obtained without creation of the Moire effects. Methods of making and using the inkjet receptor medium are also disclosed.

Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
C08F 246
US Classification:
427466, 427511, 522 90, 522 96, 522 97, 522 81, 522 83, 347 1
Abstract:
Low viscosity, radiation curable urethane oligomer, preferably a radiation curable polyester urethane oligomer, that can be incorporated into radiation curable ink compositions. Preferred embodiments are suitable for ink jetting applications. The ink jettable embodiments are particularly well-suited for use in piezo ink jet printers. The viscosity characteristics of the compositions are such that conventional solvent is not required in order to satisfy the requisite low ink jet viscosity specifications. The oligomer generally is a reaction product of ingredients comprising an aliphatic polyisocyanate; and a radiation curable, polyester alcohol comprising one or more radiation curable moieties, one or more hydroxyl moieties, and one or more ester moieties.

Method And Apparatus For Radiation Curing Of Ink Used In Inkjet Printing

US Patent:
6543890, Apr 8, 2003
Filed:
Dec 19, 2001
Appl. No.:
10/028587
Inventors:
Caroline M. Ylitalo - Stillwater MN
Ronald K. Thery - New Brighton MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B41J 201
US Classification:
347102
Abstract:
Inkjet printing apparatus includes a print head for directing radiation curable ink onto a substrate and a curing device for directing radiation along a path toward ink received on the substrate. The apparatus includes a shield and a mechanism for selectively moving the shield into and out of the path of radiation. Control of movement of the shield enables the intensity of radiation received on the substrate to be varied to ensure that the substrate does not overheat during a curing operation.

Method And Apparatus For Inkjet Printing Using Uv Radiation Curable Ink

US Patent:
6550906, Apr 22, 2003
Filed:
Nov 15, 2001
Appl. No.:
10/000282
Inventors:
Caroline M. Ylitalo - Stillwater MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B41J 201
US Classification:
347102
Abstract:
Inkjet printing apparatus includes a print head for directing radiation curable ink toward a substrate and a curing device for directing radiation toward ink received on the substrate. The apparatus includes a computer for determining desired dwell times for the ink based on characteristics of the substrate and the ink. A control device connected to the computer varies the dwell time in accordance with the desired dwell time as determined by the computer.

Rotatable Drum Inkjet Printing Apparatus For Radiation Curable Ink

US Patent:
6554414, Apr 29, 2003
Filed:
Nov 15, 2001
Appl. No.:
10/001101
Inventors:
Caroline M. Ylitalo - Stillwater MN
Bruce A. Nerad - Oakdale MN
Richard L. Severance - Stillwater MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
B41J 201
US Classification:
347102
Abstract:
Inkjet printing apparatus includes a drum, a print head for directing radiation curable ink toward a substrate on the drum, and a curing device for directing radiation toward the ink that is received on the substrate. The curing device is selectively operable to direct radiation toward a certain portion of the ink received on the substrate only after that certain portion has moved with the substrate and the drum through an arc that is at least 360 degrees. In this manner, the ink on the substrate has sufficient time to spread and level and the resultant image is of high quality.

Inks And Other Compositions Incorporating Limited Quantities Of Solvent Advantageously Used In Ink Jetting Applications

US Patent:
6558753, May 6, 2003
Filed:
Nov 9, 2000
Appl. No.:
09/711345
Inventors:
Caroline M. Ylitalo - Stillwater MN
Richard L. Severance - Stillwater MN
Ronald K. Thery - New Brighton MN
Assignee:
3M Innovative Properties Company - St. Paul MN
International Classification:
C09D 1100
US Classification:
427466, 522 75, 522 79, 522 83, 522 96, 522 97
Abstract:
Radiation curable inks with moderate amounts of solvent with low surface tension provide unique processability characteristics that allow ink jetted features to be formed and cured with excellent flow, adhesion, dot gain, compatibility, weatherability, and curing characteristics. In a representative printing method, an ink jettable ink composition is provided that includes one or more oligo/resins, a radiation curable, reactive diluent having a surface tension and 1 to 15 weight percent of a solvent component comprising a solvent having a surface tension. The solvent surface tension is no more than about, and preferably at least 2 dynes/cm less than, the surface tension of the reactive diluent. The ink composition is ink jetted onto the substrate to form an ink jetted feature. While at least a portion of the solvent is still present in the ink jetted feature, the ink jetted feature is exposed to an amount of curing energy under conditions effective to at least substantially cure the radiation curable component of the printed feature and to at least substantially dry the ink jetted feature.
