Disclosed is an ink composition for jet printer, comprising a pigment, a film forming resin and an organic solvent, the film forming resin being an acrylic copolymer containing, as a monomer unit, at least one of compounds represented by the general formulas (1) and (2):
wherein R 1 represents a hydrogen atom or a methyl group; R 2 represents an alkylene group having 2 to 12 carbon atoms which may be linear or branched; and R 3 and R 4 each independently represents a hydrogen atom, an alkyl group, an alkenyl group or an aryl group, and the sum of the number of carbon atoms of R 3 and R 4 is from 4 to 12, or R 3 and R 4 form a saturated or unsaturated hydrocarbon group which is a five-membered ring formed by combination of the R 3 and R 4 ; and
wherein R 1 represents a hydrogen atom or a methyl group; R 2 represents an alkylene group having 2 to 12 carbon atoms which may be linear or branched; and X represents a group selected from the group consisting of groups represented by the general formulas (3) to (9). |
