A resin composition comprising 100 parts by mass of a polymer (A) and 0.5 parts to 60 parts by mass of a high dielectric material (B), the high dielectric material (B) having a relative dielectric constant at 20&#xb0; C. of 10 or more, a melting point of 45&#xb0; C. or lower, and a boiling point of 150&#xb0; C. or higher.

Resin composition, resin sheet, and resin laminate

Provided are an acrylic resin composition, an acrylic resin sheet, and an acrylic resin laminate that exhibit superior transparency and impact resistance. The acrylic resin composition contains 100 parts by mass of an acrylic polymer (A) having 50 to 100% by mass of a methyl methacrylate unit and 0.002 to 0.7 parts by mass of an olefin-alkyl (meth)acrylate copolymer (B). The copolymer (B) is preferably an ethylene-alkyl acrylate copolymer (B-2). The acrylic resin sheet contains this acrylic resin composition. The acrylic resin sheet has a haze value of 0.5% or less based on JIS K 7136, a 50% impact-puncture height of at least 350 mm or more in a falling ball test based on JIS K 7211 under the described conditions, and a sheet thickness of 2 mm or less. The acrylic resin laminate has a cured layer laminated on at least one surface of the acrylic resin sheet.

Acrylic resin composition, acrylic resin sheet, acrylic resin laminate, and manufacturing method for same

Disclosed is a resin laminate having a surface layer excellent in antistatic properties, scratch resistance, and transparency. Also disclosed is a method for producing the resin laminate with a high productivity. Further disclosed is a transfer film for use in the production of the resin laminate. The resin laminate comprises a resin shaped article, an antistatic layer containing a &#x3c0;-electron conjugated conductive polymer and at least one resin selected from a polyester resin, a polyurethane resin, a polyesterurethane resin, an acrylic resin, and a melamine resin on at least one surface of the shaped article, and a cured coating film layer obtained by curing a curable resin on the antistatic layer. The method for producing the resin laminate preferably comprises the steps of forming the cured coating film layer and the antistatic layer on a mold using a transfer film, carrying out cast polymerization of a raw material for a resin, and detaching the resin laminate from the mold after the polymerization is completed.
