<p>PROBLEM TO BE SOLVED: To provide a resin composition which, when stuck to the surface of plastic moldings, can prevent blistering, such as bulging or rolling up, and to provide a pressure-sensitive adhesive composition, a pressure-sensitive adhesive sheet, and a sheet or plastic laminate prepared by using the composition. SOLUTION: This resin composition is obtained by copolymerizing (A) 80-99 wt.% alkyl (meth)acrylate monomer and (B) 1-20 wt.% carboxylatedα,β- ethylenically unsaturated monomer in acetone and has a wt. average mol.wt. of 1,500,000 or higher and a ratio of wt. average mol.wt./number average mol.wt. of 4.0 or lower. When a composition prepared by compounding the above composition in an amount of 100 pts. with 2 pts. trimethylolpropane adduct of tolylene diisocyanate is applied in a coating wt. of 20 g/m2 to polyethylene terephthalate and then laminated to a polycarbonate sheet and the resultant laminate is left standing in an oven at 100 deg.C for 30 days, blistering does not occur.</p> |
