Abstract
The present invention provides an acrylic resin laminated film comprising a first layer comprising an acrylic resin and a second layer comprising a resin composition comprising (a) an acrylic resin and an olefin-based copolymer obtained by copolymerization of an olefin and at least one monomer selected from the group consisting of unsaturated carboxylic acids, unsaturated carboxylates, unsaturated carboxylic anhydrides and vinyl acetate, or (b) an olefin-based copolymer obtained by copolymerization of an olefin and a monomer having glycidyl group in a side chain, which has excellent melt-adhesion to both of an acrylic resin and a polyolefin-based resin and additionally, and a laminated article which, due to the use of this acrylic resin laminated film, has excellent transparency, ornamental property, surface hardness, weather-resistance, oil-resistance and the like which are characteristics of an acrylic-resin constituting the most outer surface, and additionally, manifests excellent molding processability, recycling property, punching and bending processability, heat-resistance, cold-resistance and the like which are characteristics of a polyolefin-based resin which is a substrate.
