<p>The sheet material of the present invention has a protecting layer which comprises a heat reactant of a heat and active energy ray curable resin composition comprising as an active ingredient a polyfunctional isocyanate and a polymer having a (meth)acryl equivalent weight from 100 to 300 g/eq, a hydroxyl value from 20 to 500 and a weight-average molecular weight from 5000 to 50000. And, this protecting layer applied to the surface of a molded article is cured by active energy ray irradiation. Therefore, a molded article excellent in abrasion resistance and chemical resistance can be obtained, and crack is not caused in the curved part of the molded article. Further, since the protecting layer is cured in part by heat in sheet material production, a large scale active energy ray irradiation apparatus is not required in active energy ray irradiation to realize low cost. <IMAGE></p> |
