Document Type and Number:
Japanese Patent JP2512596
Kind Code:
B2
Abstract:
PURPOSE:To prevent migration of a plasticizer stably for a long period of time and to improve adhesiveness by laminating a specific primer layer, an adhesive layer and an adherend on the surface of a soft PVC resin molding. CONSTITUTION:A primer composition is obtained by compounding a copolymer having a weight-average molecular weight of 100,000, to 500,000, which is obtained by copolymerizing 80wt.% or more methyl methacrylate and 0.5-20wt.% monomer having an amino group (e.g. aminoethylene), with a tackifier, if required. Then the primer composition is applied onto the surface of a soft PVC resin molding to form a primer layer 1-20mu thick, and an adherend is laminated onto the primer layer through an acrylic adhesive layer.
