Patent ID: 8240838

Claim:
An ink composition for inkjet recording, comprising: a monomer containing a fluorinated alkylene group and two or more polymerizable groups, each of the two or more polymerizable groups being independently selected from the group consisting of an acrylic acid ester group, a methacrylic acid ester group, an itaconic acid ester group, a crotonic acid ester group, an isocrotonic acid ester group, a maleic acid ester group, and a styrene group; a photo initiator; and a polymerizable monomer that is provided in addition to the monomer containing a fluorinated alkylene group and two or more polymerizable groups; wherein the monomer containing a fluorinated alkylene group and two or more polymerizable groups is at least one selected from the group consisting of: (i) a monomer including a chain structure containing a fluorinated alkylene group, the monomer being represented by the following formula (2), and (ii) a monomer containing a ring structure having two or more chain-shaped substituents and containing a fluorinated alkylene group, and having two or more polymerizable groups respectively provided at terminals of at least two of the two or more chain-shaped substituents: B L 2 -X) n1 Formula (2) wherein in formula (2), L represents a fluorinated alkylene group, X represents a polymerizable group, B represents a branched group having three or more bonds, and n1 is an integer of 3 or more.
