Acrylic resin composition and laminate formed by laminating same

Abstract

Disclosed is an acrylic resin composition that has excellent weather resistance and can be stably produced at high temperatures. Specifically, disclosed is an acrylic resin composition including, with respect to 100 parts by mass of an acrylic resin, from 0.1 to 8 parts by mass of a triazine-based UV absorber including 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[2-(2-ethylhexanoyloxy)ethoxy]phenol, wherein the acrylic resin used is an acrylic resin including at least 80 wt % of methyl methacrylate as a monomer component, and having a glass transition temperature of at least 80° C.

1 . An acrylic resin composition comprising, with respect to 100 parts by mass of an acrylic resin, from 0.1 to 8 parts by mass of a triazine-based UV absorber including 2-(4,6-diphenyl-1,3,5-triazin-2-yl)-5-[2-(2-ethylhexanoyloxy)ethoxy]phenol, wherein the acrylic resin includes at least 80 wt % of methyl methacrylate as a monomer component, and has a glass transition temperature of at least 80° C. 
     
     
         2 . The acrylic resin composition according to  claim 1 , wherein the acrylic resin is obtained by polymerizing from 80 to 100 wt % of methyl methacrylate, and from 20 to 0 wt % of an alkyl (meth)acrylate that includes a linear or branched alkyl group including at least two carbon atoms. 
     
     
         3 . A molded article obtained by melting and mixing/kneading the acrylic resin composition according to  claim 1  within a temperature range of from 200 to 260° C. 
     
     
         4 . A laminate in which a surface of a support material is covered by a thermoplastic resin layer having a thickness of from 30 to 300 μm, wherein the thermoplastic resin layer is formed by melting and mixing/kneading the acrylic resin composition according to  claim 1  within a temperature range of from 200 to 260° C. 
     
     
         5 . The laminate according to  claim 4 , wherein the support material is selected from a vinyl chloride resin or a polycarbonate resin. 
     
     
         6 . A molded article obtained by melting and mixing/kneading the acrylic resin composition according to  claim 2  within a temperature range of from 200 to 260° C. 
     
     
         7 . A laminate in which a surface of a support material is covered by a thermoplastic resin layer having a thickness of from 30 to 300 μm, wherein the thermoplastic resin layer is formed by melting and mixing/kneading the acrylic resin composition according to  claim 2  within a temperature range of from 200 to 260° C.
