Abstract:
1. A method of coating a substrate, comprising: applying a primer composition to a polyolefin resin substrate; wherein the primer composition comprises a polymer (A) having a unit of a (meth)acrylic ester monomer (a) in which acryloyloxy group or methacryloyloxy group is bonded to secondary carbon atom or tertiary carbon atom and a unit of monomer (b), wherein the (meth)acrylic ester monomer (a) is at least one selected from the group consisting of 4-t-butylcyclohexyl acrylate, tricyclodecanyl acrylate, 3,3,5-trimethylcyclohexyl acrylate, and t-butylmethacrylate; and the monomer (b) is at least one selected from the group consisting of (meth)acrylic esters, monomers having hydroxyl group in a molecule, methacrylic acid and styrene, and the content of the unit of monomer (a) in the polymer (A) is no less than 80% by mass and the content of the unit of the monomer (b) in the polymer (A) is no more than 20% by mass.
