Patent ID: 8822132

Claim:
A colored dispersion, comprising: a binder resin copolymer including 40-60 mol % of monomers represented by the following Formula 1, 5-10 mol % of polyethyleneglycolmonomethacrylate, 15-35 mol % of monomer represented by the following Formula 3, and 15-20 mol % of monomers represented by the following Formula 4, the binder resin copolymer being in the amount of 0.2 to 9% by weight based on the colored dispersion, a dispersing agent in the amount of 0.2 to 9% by weight based on the colored dispersion, a pigment in the amount of 10 to 30% by weight based on the colored dispersion, and a solvent as a residue, Wherein, R 1 represents hydrogen, or a radical, which forms an imide structure or a five-membered cyclic carboxylic anhydride with R x , R 2 is methyl and R 3 is selected from the group consisting of hydrogen, methyl and hydroxyl methyl, R 4 represents hydrogen or a methyl group, R X is selected from the group consisting of C 1 to C 12 alkyl esters, C 2 to C 6 alkyl esters substituted with 1 or 2 hydroxy groups, C 2 to C 6 alkyl esters substituted with C 1 to C 3 alkoxy groups, C 1 to C 6 alkyl esters substituted with halogen groups, C 1 to C 3 alkoxy poly(n=2 to 30) alkylene, C 2 to C 3 glycol esters, C 1 to C 6 alkyl esters substituted with phenyl groups, phenyl substituted with C 1 to C 6 alkyl groups, phenyl substituted with C 1 to C 6 alkoxy groups, phenyl substituted with halogen groups, C i to C 6 alkoxy methyl groups, glycidoxy methyl group, C 5 to C 15 cyclic alkyl esters, C 6 to C 12 aromatic groups, and a radical that forms an imide structure or a five-membered cyclic carboxylic anhydride together with R 1 , R Z is obtained by the reaction product of the hydroxyl group of a polyethyleneglycol monomethacrylate with a carboxylic anhydride and represents a part of the reaction product of the anhydride and the —OH of the polyethyleneglycol monomethacrylate, and X represents 1 to 4, and y represents 1 to 3.
