Patent number: 6866379Abstract: An ink jet ink composition including from 40.0 to 99.0% by weight of water; from 0.1 to 20.0% by weight of a pigment dispersed with an oleoyl methyl taurine salt dispersant from 0 to 70.0% by weight of a water miscible co-solvent; and from 0.1 to 20.0% by weight of a water-reducible addition polymer; wherein the weight average molecular weight of the polymer is from 2,000 to 100,000; the acid number is from 50 to 400; and the acid group on the polymer is neutralized by an alkaline metal hydroxide such as lithium hydroxide, sodium hydroxide potassium hydroxide, or a mixture thereof; and wherein all weight percentages are based on the total weight of the ink composition. An ink jet printing method is also disclosed.Type: GrantFiled: October 31, 2002Date of Patent: March 15, 2005Assignee: Eastman Kodak CompanyInventors: Hwei-Ling Yau, Wendy S. Krzemien, Elmer C. Flood

Patent number: 6645705Abstract: The present invention is a photographic element which includes a support, at least one silver-halide emulsion layer superposed on the support and a processing-solution-permeable overcoat overlying the silver-halide emulsion layer that becomes water-resistant in the final product, without requiring lamination or fusing. The presence, in the coating composition, of a compound comprising a blocked copolymer of ethylene oxide and propylene oxide has been found to improve wet durability, prevent the retention of iron, and improve the conversion of the overcoat to a water-resistant layer during processing. The present invention is also directed to a method of making a photographic print involving developing the photographic element.Type: GrantFiled: November 5, 2001Date of Patent: November 11, 2003Assignee: Eastman Kodak CompanyInventors: Hwei-Ling Yau, Kevin M. O'Connor, Elmer C. Flood, David E. Decker

Patent number: 6395459Abstract: The present invention relates to imaged elements having a protective overcoat that resists fingerprints, common stains, and spills. In particular, a curable overcoat composition is applied to an imaged element that contains a curing agent incorporated into a top layer of the element, resulting in a cured water-resistant or spill resistant overcoat. The invention can be used to protect photographic elements and recording media. In one embodiment of the invention, a UV-curable material and a water-dispersible latex is applied to a photographic print containing a photoinitiator incorporated into the original print.Type: GrantFiled: September 29, 2000Date of Patent: May 28, 2002Assignee: Eastman Kodak CompanyInventors: Jeffrey F. Taylor, Thomas H. Whitesides, Hwei-Ling Yau, Elmer C. Flood, John W. Boettcher

Patent number: 6352805Abstract: The present invention is directed to an imaged element that includes a support, at least image-receiving layer superposed on the support and a water-resistant protective overcoat overlying the image-receiving layer that is water-resistance. The present invention is also directed to a method of making a print by application of a UV-curable water-dispersible latex.Type: GrantFiled: September 25, 2000Date of Patent: March 5, 2002Assignee: Eastman Kodak CompanyInventors: Jeffrey F. Taylor, Kevin M. O'Connor, Elmer C. Flood, Hwei-Ling Yau, Tienteh Chen

Patent number: 6258520Abstract: The present invention relates to imaging elements, including photographic elements and recording media, having a protective overcoat that resists fingerprints, common stains, and spills. More particularly, the present invention provides a processing-solution-permeable protective overcoat that is water resistant in the final processed product. The overcoat, before formation of the image, comprises hydrophobic polymeric particles in a gelatin matrix. Subsequent treatment of the overcoat, after formation of the image, to remove the gelatin, causes coalescence of the hydrophobic particles, resulting in the formation of a water-resistant continuous protective overcoat.Type: GrantFiled: September 29, 2000Date of Patent: July 10, 2001Assignee: Eastman Kodak CompanyInventors: Hwei-Ling Yau, Thomas H. Whitesides, Elmer C. Flood, Amy E. Jasek

Patent number: 5958660Abstract: This invention comprises a composition containing a hydrophilic colloid and a water soluble polymer of boric acid, and optionally a hardening agent for the hydrophilic colloid. The hydrophilic colloid is preferably gelatin. This invention also comprises a photographic element in which at least one layer thereof contains a hydrophilic colloid and a water-soluble polymer of boric acid and a method of making the photographic element.Type: GrantFiled: December 31, 1997Date of Patent: September 28, 1999Assignee: Eastman Kodak CompanyInventors: Jeffrey F.

Patent number: 5952130Abstract: The present invention is an imaged photographic element which includes a support, at least one light sensitive silver halide emulsion layer superposed on the support, and an overcoat layer overlying the light sensitive silver halide emulsion layer. The protective overcoat includes a first water insoluble polymer having a Tg less than 25.degree. C. and a second water insoluble polymer having a Tg greater than 25.degree. C. The first or second polymer is composed of a monomer at a weight percent of 20 to 100 having the following formula ##STR1## wherein: X is selected from the group consisting of --Cl, --F, and --CN, and Y is each independently selected from the group consisting of H, Cl, F, CN, CF.sub.3, CH.sub.3, C.sub.2 H.sub.5, n--C.sub.3 H.sub.7, iso--C.sub.3 H.sub.7, n--C.sub.4 H.sub.9, n--C.sub.5 H.sub.11, n--C.sub.6 H.sub.13, OCH.sub.3, OC.sub.2 H.sub.5, phenyl C.sub.6 F.sub.5, C.sub.6 Cl.sub.5, CH.sub.2 Cl, CH.sub.2 F, C.sub.2 F.sub.5, n--C.sub.3 F.sub.7, iso--C.sub.3 F.sub.7, OCF.sub.3, OC.sub.2 F.Type: GrantFiled: August 19, 1998Date of Patent: September 14, 1999Assignee: Eastman Kodak CompanyInventors: Hwei-Ling Yau, Tienteh Chen, Jeffrey F.
