PROBLEM TO BE SOLVED: To provide a primer compsn. which exhibits a very high adhesive power even when exposed to alkaline conditions. SOLUTION: This compsn. comprises (A) an acrylic copolymer having a reactive silyl group and formed from (a) a monomer having a carbon-bonded reactive silyl group represented by the formula (wherein R<1> is H or 1-10C alkyl; R<2> is H, 1-10C alkyl, aryl or aralkyl; and a is 0, 1 or 2), (b) an alkyl(meth) acrylate monomer having a 10C or higher alkyl group, and (c) other copolymerizable monomers and (B) an aminosilane compd. and/or a reaction product thereof. |
