Ink solvent assisted heat sealable media
First Claim
1. A printed image on a print medium, comprising:
- a) a media substrate;
b) a porous ink-receiving layer coated on the media substrate, said porous ink-receiving layer including semi-metal oxide or metal oxide particulates;
c) a latex layer coated on the porous ink-receiving layer, wherein the latex layer includes latex particulates having a glass transition temperature from about 50°
C. to about 120°
C.; and
d) an ink-jet ink comprising a film promoting additive printed on at least a portion of the latex layer forming ink-associated regions of the latex layer exclusive of non-printed latex regions, said ink-jet ink being received at least partially by the porous ink-receiving layer, wherein at least a portion of the ink-associated regions of the latex layer include a continuous film and the non-printed latex regions of the latex layer do not include a continuous film.

Abstract
A method of producing a print medium to reduce problems associated with the gradual dye-fade and color-shift of inks over time, and to provide improved resistance to physical handling is provided Specifically, a method can comprise steps of coating a media substrate with a porous coating composition of semi-metal oxide or metal oxide particulates to form a porous ink receiving layer, coating the porous ink-receiving layer with a latex layer configured to allow an ink-jet ink to be received at the porous ink-receiving layer, printing ink-jet ink on at least a portion of the latex layer to form ink-associated latex regions exclusive of non-printed latex regions, and heating the latex layer. The ink-jet ink can include an ink vehicle, a colorant, and a film promoting additive that lowers the film forming temperature of the latex particulates in the ink-associated latex regions. Upon heating, the ink-associated latex regions form a continuous film, and non-printed latex regions do not form a continuous film. Associated systems and ink-jet prints are also provided.

34. A printed image on a print medium, comprising:
-
a) a media substrate; b) a porous ink-receiving layer coated on the media substrate, said porous ink-receiving layer including semi-metal oxide or metal oxide particulates; c) a latex layer coated on the porous ink-receiving layer, where the latex layer includes latex particulates that function as a binder; and d) an ink-jet ink comprising a film promoting additive printed on at least a portion of the latex layer forming ink-associated regions of the latex layer exclusive of non-printed latex regions, said ink-jet ink being received at least partially by the porous ink-receiving layer, wherein at least a portion of the ink-associated regions of the latex layer include a continuous film and the non-printed latex regions of the latex layer do not include a continuous film, wherein the latex particulates in the non-printed latex regions comprise an inner portion with a higher glass transition temperature and an outer portion with a lower glass transition temperature, wherein the higher glass transition temperature and the lower glass transition temperature are configured such that when the latex is applied at an application temperature, the inner portion is non-tacky and the outer portion is tacky. - View Dependent Claims (35, 36, 37, 38, 39, 40)
