PURPOSE:The titled composition providing imitations such as foods, cakes, etc. indistiguishable from real things, having improved weather resistance, molding and processing properties, water resistance, etc., obtained by blending a hydroxylated polysiloxane with specific amounts of a specific silane, an organotin compound and a filler with specified particle diameter. CONSTITUTION:(A) 100pts.wt. hydroxylated polysiloxane shown by the formula I (R<1> and R<2> are monofunctional hydrocarbon, halogenated hydrocarbon, etc.; n is positive integer) is blended with (B) 0.5-20pts.wt. one or more of B1: oxime-substituted silane shown by the formula II [R<3> is H, monofunctional hydrocarbon, etc.; X is CR'R'' (R' and R'' are equal to R<3>), etc.; n' is 0-3], B2: alkoxy- or acyloxy-substituted silane shown by the formula III (R<4> is monofunctional hydrocarbon, etc.; R<5> is alkyl, etc.; n'' is 0-3) or B3: amine-or amide- subsituted silane shown by the formula IV (R<6>, R<7>, and R<8> are H, etc.; n''' is 0- 3), (C) 0.005-2pts.wt. organotin compound, and (D) 0.5-50pts.wt. filler having 50-2,000mu average particle diameters.
