Abstract
A water-resistant ink jet ink composition comprising from about 0.5% to about 5% by weight of a pigment, a carrier, and from about 0.1% to about 2% by weight of a photo-crosslinkable polymeric dispersant having the following formula: (A)x(B)y(C)z wherein: A represents repeating units of an ethylenically unsaturated group; B represents repeating units of an ethylenically unsaturated group containing at least one photo-crosslinkable group; C represents repeating units of an ethylenically unsaturated group which provides water-dispersibility or water-solubility to the dispersant; x is from 0% to 80 mole %; y is from 0.1% to 100% mole %; and, z is from 0% to 99.9 mole %.
Claims9
A water-resistant ink jet ink composition comprising from about 0.5% to about 5% by weight of a pigment, a carrier, and from about 0.1% to about 2% by weight of a photo-crosslinkable polymeric dispersant having the following formula:
- (A)x(B)y(C)z
- wherein:
- A represents repeating units of an ethylenically unsaturated group wherein A is selected from the group consisting of styrene derivatives, an alkyl acrylate or methacrylate, vinyl acetate, vinyl chloride, acrylonitrile, olefins, or flourine-containing olefins;
- B represents repeating units of an ethylenically unsaturated group containing at least one photo-crosslinkable group;
- C represents repeating units of an ethylenically unsaturated group which provides water-dispersibility or water-solubility to the dispersant;
- x is from 0% to 80 mole %;
- y is from 0.1% to 100% mole %;
- and,
- z is from 0% to 99.9 mole %.
