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&#xb0; 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.

Acrylic resin film, method of producing the same, and laminate using the same

An acrylic film with excellent flexibility is easy to process and has 70 to 95 parts by weight of an acrylic rubber-containing polymer (A) and to 30 parts by weight of an acrylic-based thermoplastic polymer (B) and having a total amount of (A) and (B) of 100 parts by weight; a gel content of 50 to 70% by weight; and elongation at break in one direction of 180% or more. The acrylic rubber-containing polymer (A) has an elastic copolymer having a monomer unit whose polymer has a glass transition temperature of more than 65&deg; C. The acrylic-based thermoplastic polymer (B) has a glass transition temperature of 65&deg; C. or less and a weight average molecular weight of 100,000 to 300,000.

Acrylic films and acrylic laminates

Disclosed is a technology for providing a thermoplastic resin composition or resin laminate having an excellent mat property by using, as matting agent, a copolymer (B) prepared by polymerizing 0.5 to 80% by weight of a hydroxyalkyl (meth)acrylate having a C.sub.1-8 alkyl group and 10 to 99% by weight of an alkyl methacrylate having a C.sub.1-13 alkyl group, with a C.sub.1-8 alkyl acrylate, vinyl aromatic monomer, another vinyl monomer, and a cross-linking monomer being optional.
