Patent ID: 8829078

Claim:
An ink composition for inkjet recording, comprising: as Component A, a urethane oligomer or polymer that has at least one repeating unit selected from the group consisting of Formula (11), Formula (12) and Formula (13): wherein: in Formula (11), R 1 and R 2 each independently represents a hydrogen atom or an alkyl group, and R 1 and R 2 optionally bond to each other to form a ring, in Formula (12), R 3a , R 3b , R 3c and R 3d each independently represents a hydrogen atom, an alkyl group, an alkoxy group, an aryloxy group, an alkoxycarbonyl group, an aryloxycarbonyl group or a halogen atom; R 3a , R 3b , R 3c or R 3d optionally bond to another of R 3a , R 3b , R 3c or R 4d to form a ring; and R 4 represents a hydrogen atom, an alkyl group or an aryl group, in Formula (13), R 5 and R 6 each independently represents a hydrogen atom, an alkyl group or an aryl group, and R 5 and R 6 optionally bond to each other to form a ring, and in Formulae (11) to (13), X 1 , X 2 and X 3 each independently represents a residue obtained by removing three hydrogen atoms from at least one compound selected from the group consisting of an alkane having from 3 to 10 carbon atoms and a cycloalkane having from 3 to 10 carbon atoms; Y 1 represents an alkylene group having 1 to 20 carbon atoms; and Y 2 and Y 3 each independently represents a single bond or an alkylene group; and as Component B, an organic solvent.
