PURPOSE:To obtain the title composition which can give a molding having excellent mold release and coatability by using a specified resin composition wherein the internal mold release comprises a specified imide compound. CONSTITUTION:A resin composition comprising an aliphatic, alicyclic or aromatic polyisocyanate (A), a polyol or prim., sec. or aromatic prim. amino- terminated polyester (B) having at least two active hydrogen groups and a molecular weight of 8,000-12,000, 5-80pts.wt., per 100pts.wt. polyol or polyether of component B, aromatic diamine chain extender (C) and an internal mold release (D), and having an isocyanate index of 70-130, wherein component D is an amide compound of formula I [wherein R is an 8-24 C aliphatic (un)saturated hydrocarbon group; and A1 is an aliphatic, alicyclic or aromatic tetravelent group], formula II [wherein R3 is R; and R1 and R2 are each a 1-24 C (un)saturated hydrocarbon group] or formula III [wherein R4 is R; A2 is an (un)saturated hydrocarbon group; aliphatic or aromatic group and is a bivalent group all or part of whose constituting atoms constitute a six- or five-membered cyclic imide group]. |
