(57) [Summary] (Modified) [Objective] To provide a crystalline synthetic resin composition having improved transparency, mechanical properties and the like. [Structure] At least 0.01 to 5 parts by weight of a dibenzylidene sorbitol derivative represented by the following general formula (I) and 100 parts by weight of a crystalline synthetic resin and the following general formula (II) or ( A crystalline synthetic resin composition comprising 0.01 to 5 parts by weight of at least one metal salt of an aromatic organic phosphate represented by III). (In the formula, R 1 , R 2 , R 3 and R 4 represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms. Provided that at least one of R 1 and R 2 or R 3 and R 4 is alkyl. It represents a group.) (In the formula, R 5 represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms, and R 6 , R 7 , R 8 , R 9 and R 10 are each a hydrogen atom and an alkyl group having 1 to 12 carbon atoms. And M 1 and M 2 represent an alkali metal atom, an alkaline earth metal atom, a zinc atom or an aluminum atom, p represents 1 or 2, q represents 0 when M 1 and M 2 are alkali metal atoms, alkaline earth metal atoms or zinc atoms, and 1 or 2 when M 1 and M 2 are aluminum atoms.
