Abstract

The disclosure relates to a crystal nucleating agent composition including a compound represented by formula (1) and a compound represented by formula (2). R1 is a C1-C4 alkyl group, R1 binds to the carbon at position 3 or 4 of a cyclohexane ring. When M1 is a calcium ion or a hydroxyaluminum ion, a is 2, and b is 1, and when M1 is a sodium ion or a lithium ion, a is 1, and b is 2. R2 to R5 are the same or different, and each represents a hydrogen atom or a C1-C9 alkyl group, R6 is a hydrogen atom or a C1-C3 alkyl group. When M2 is an alkali metal ion, c is 1, and d is 1, and when M2 is an alkaline earth metal ion, a zine ion, or a hydroxyaluminum ion, c is 2, and d is 2.
