RESIN SUBSTRATE PROVIDED WITH HARD-COAT COATING, AND METHOD FOR PRODUCING SAME

摘要

The present invention addresses the problem of providing a resin substrate provided with a hard-coat coating which is superior in weatherproof adhesion and weatherproof crack-resistance. A resin substrate provided with a hard-coat coating (1), having, on at least one surface of a resin substrate (2), a primer layer (3) containing an acrylic-based polymer (P) as a primary component, and a hard-coat layer (4) in this order from the resin substrate (2), a silyl group-containing acrylic polymer (a) contained in the primer layer (3) containing methyl methacrylate (MMA)-based polymer units as well as silyl group-containing polymer units, and not containing polymer units having an aromatic hydrocarbon group on a side chain, and the value obtained by dividing the acrylic-based polymer (P) content by the sum of the acrylic-based polymer (P) content and the silyl group-containing acrylic-based (a) content and multiplying by 100 being 50 to 98 mass%.
