Abstract
Disclosed is an actinic ray curable ink-jet ink comprising a an epoxy compound having at least two oxirane rings and a linkage chain linking the two oxirane rings, wherein the linkage chain has a branched structure.
Claims9
An actinic ray curable ink-jet ink comprising an alicyclic epoxy compound represented by the following formula (VI) or (VII),
- wherein R601 represents an aliphatic group which is positioned at the position other than the α or β-position of the oxirane rings;
- m6 represents an integer of from 0 to 2;
- X1 represents —(CH2)n6— or —(O)n6, in which n6 represents an integer of 0 or 1;
- r1 represents an integer of from 1 to 3;
- and L3 represents a (r1+1)-valent linkage group having a branched structure, provided that the linkage group may contain an oxygen atom or a sulfur atom in the main chain,
- wherein R701 represents an aliphatic group which is positioned at the position other than the α or β-position of the oxirane rings;
- m7 represents an integer of from 0 to 2;
- X2 represents —(CH2)n7— or —(O)n7—, in which n7 represents an integer of 0 or 1;
- r2 represents an integer of from 1 to 3;
- L4 represents a (r2+1)-valent linkage group having a branched structure, provided that the linkage group may contain an oxygen atom or a sulfur atom in the main chain;
- and p2 and q2 independently represent an integer of 1 or 2.
