<p>PURPOSE:To obtain the title coating composition having high curing rate, excellent adaptability to offset printing, washable with petroleum-based solvent, comprising diallyl phthalate-based polymer, macromonomer solid at normal temperature and ethylenic unsaturated compound. CONSTITUTION:(A) A diallyl phthalate-based polymer having 1,000-100,000 weight-average molecular weight and 40-180 deg.C softening point is blended with (B) a macromonomer containing an ethylenic unsaturated bond at the end of molecular chain having 1,000-100,000 weight-average molecular weight and 40-180 deg.C softening point, comprising a segment component consisting of a copolymer of styrene and/or styrene derivative and a (meth)acrylate of monohydric alcohol, in a ratio of (5:95)-(95:5) and the blend is dissolved in (C) an ethylenic unsaturated compound to give the objective coating composition.</p> |
