<p>PROBLEM TO BE SOLVED: To obtain a film or sheet having an excellent ability to intercept ultraviolet rays and does not undergo bleeding causing impaired surface appearance during storage by adding a specified amount of a compound selected among a plurality of benzotriazole compounds and a triazine compound to a PP resin and molding the mixture. SOLUTION: This film or sheet is prepared by adding 0.01-5 pts.wt. at least one compound selected among 2-(2-hydroxy-5-t-octylphenyl)benzotriazole, 2-(2H- benzotriazol-2-yl)-6-dodecyl-4-methylphenol, a compound of formula I and a compound of formula II to 100 pts.wt. PP resin and molding the resulting mixture. In the formulae, R<1> to R<8> are each H, a 1-10C alkyl, an aryl, or an alkoxyl. The PP resin used is desirably the one having a melting peak temperature (Tm) of 150 deg.C or above (as measured with a differential scanning colorimeter(DSC) and a tensile modulus of 200-700 MPa.</p> |
