<P>PROBLEM TO BE SOLVED: To provide a nucleating agent that is suitable to promote the crystallization of a polylactic acid resin, and is metal free, and to provide a resin composition that includes the nucleating agent and a polylactic acid resin. <P>SOLUTION: The polylactic acid resin composition includes: 100 pts.mass of a polylactic acid resin; and 0.01-10 pts.mass of a salt of a phenyl phosphonic acid compound shown by formula [1] with at least one amine compound chosen from the group consisting of amine compounds shown by formula [2] and formula [3]. In the formula [1], R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>each independently denote a hydrogen atom, a C1-10 alkyl group or a C2-11 alkoxycarbonyl group, in the formula [2], R<SP POS="POST">3</SP>denotes a C3-10 cyclic alkyl group or a C7-12 aralkyl group, and in the formula [3], R<SP POS="POST">4</SP>denotes a n-valent C1-6 aliphatic hydrocarbon group or a n-valent C6-10 aromatic hydrocarbon group, and n denotes an integer of 2-4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
