Patent ID: 7303787

Claim:
An active ray curable ink-jet composition comprising: (i) a colorant; and (ii) a set of (I) or a set of (II), wherein the set of (I) contains: (a) at least one photopolymerizable compound represented by Formula (1): wherein Y 1 - Y 8 are chosen from a hydrogen atom, an alkyl group, a carbonyl group, an ether group, an alkenyl group, an oxiranyl group, a functional group having an alkyl alkanoate group and an alicyclic epoxy group, or a functional group having a carboxylate group and an alicyclic epoxy group; and (b) a diol compound represented by Formula (2), which is present in the composition in an amount ranging from 0.1 to 10% by weight, relative to the total weight of the active ray curable ink composition: wherein Z 1 -Z 8 are chosen from a hydrogen atom, an alkyl group, a carbonyl group, an ether group, an alkenyl group, an oxiranyl group, an alkyldiol group, a functional group having an alkyl alkanoate group and an alicyclic epoxy group, a functional group having an alkyl alkanoate group and an alicyclic diol group, a functional group having a carboxylate group and an alicyclic diol group, or a functional group having a carboxylate group and an alicyclic epoxy group; and the set of (II) contains: (a) a photopolymerizable oxetane compound; (b) a photopolymerizable compound represented by Formula (1a): wherein R 1 is chosen from an alkyl group having 1-10 carbon atoms, an aromatic group, or an acyl group; and (c) a diol compound represented by Formula (2a), which is present in the composition in an amount ranging from 0.1 to 10% by weight, relative to the total weight of the active ray curable ink-jet composition: wherein R 2 is chosen from an alkyl group having from 1 to 10 carbon atoms, an aromatic group, or an acyl group.
