<p>PROBLEM TO BE SOLVED: To obtain a composition which forms a coating film having excellent water resistance and excellent adhesion to polyolefins by mixing a diol di(meth) acrylate with a dimer diol di(meth)acrylate. SOLUTION: The diol di(meth)acrylate (A) used is represented by the formula: HO(XO)m -ZO-(YO)n -H (wherein Z is a dimer diol residue; X and Y are each a 2-4C alkylene; m and n are each an integer of 0 or greater; and 2<=m+n<=40). The dimer diol di(meth)acrylate (B) used is a difunctional (meth)acrylic ester prepared by (meth)acryloylating the two hydroxyl groups of the dimer diol. In addition to components A and B, a radical polymerizable monomer (C) copolymerizable therewith may be used. The mixing ratio is desirably such that A:B:C is (5-90):(5-90):(5-90)(wt.%). To perform the thermal polymerization of the composition, 0.1-5 pts.wt., per pt.wt. total monomer, benzoyl peroxide is used as a polymerization initiator.</p> |
