<p>PURPOSE:The titled ink composition with excellent adhesion, flexibility and workability, prepared by compounding a specified saturated copolyester and a specified polymerizable compd. with a photosensitizer and a pigment. CONSTITUTION:A polymerizable compd. (B) consisting of a (meth)acrylate contg. a difunctional or more highly functional (meth)acrylate [e.g., an alkylene glycol di (meth)acrylate] at least as a part thereof, and a saturated copolyester (A) of MW 1,000-15,000, soluble in said polymerizable compd. B, in which 20mol% or more saturated polyvalent carboxylic acid component is composed of an org. dicarboxylic acid (e.g., terephthalic or isophthalic acid) and the alcohol component is a 2-12C polyhydric alcohol, are used. The saturated copolyester A is mixed with the polymerizable compd. B in a wt. ratio of 20:80-80:20, and the resulting mixt. is compounded with a photosensitizer and a pigment.</p> |
