Abstract
The invention provides an ink composition including (A) a polymerization initiator and (B) a (meth)acrylic acid ester having an alicyclic group as a substituent or amide having an alicyclic group as a substituent. The ink composition preferably further contains (D) a colorant and (E) a sensitizing dye. The ink composition is used for ink jet recording.
Claims38
An ink composition comprising:
- (A) a polymerization initiator;
- (B) a (meth)acrylic acid ester or amide having an alicyclic group as a substituent and, represented by the following formula (I) or (II):
- wherein R1 represents a hydrogen atom or a methyl group;
- R2 to R12 each independently represents a hydrogen atom or an alkyl group, with the proviso that at least two of R2 to R12 respectively represent an alkyl group;
- Z represents an oxygen atom or —NR13—;
- R13 represents a hydrogen atom or an alkyl group;
- and X represents a single bond or a divalent organic group;
- and
- (C) another polymerizable compound, and
- a colorant,
- wherein the ink composition has a viscosity of from 7 to 30 mPa·s within an ejecting temperature range of from 25 to 50 ° C., and
- the content of the (B) (meth)acrylic acid ester or amide relative to the total content of the (B) (meth)acrylic acid ester or amide and the (C) other polymerizable compound is 15% by mass or higher.
