Abstract:
An acrylic resin film material comprising at least a multilayer structure polymer with a particular structure prevent a molded item from being whitened during insert- or in-mold molding and meet the requirement for surface hardness, heat resistance, and transparency or matting performance for vehicle applications. It is also possible to use an acrylic resin film material exhibiting a difference of 30% or less between haze values as determined in accordance with the testing method of JIS K7136 (haze measurement method) after and before a tensile test where a test piece with a width of 20 mm is pulled under the conditions of an initial inter-chuck distance of 25 mm, a rate of 50 mm/min and a temperature of 23° C. until an end-point inter-chuck distance becomes 33 mm as well as having a pencil hardness of 2 B or higher as determined in accordance with JIS K5400.
