Abstract
It is an object of the present invention is to provide a polylactic acid resin composition in which a crystal nucleator appropriate for accelerating crystallization of polylactic acid rein is added.A polylactic acid resin composition comprising a polylactic acid resin, and a metal salt of a phosphorus compound of formula (I)wherein R1 and R2 may be the same or different and are hydrogen atom, C1-10alkyl or C2-10alkoxycarbonyl, or a polylactic acid resin composition comprising a polylactic acid resin, and a metal salt of a phosphorus compound of formula (II)wherein R3, R4, R5 and R6 may be the same or different and are hydrogen atom, C1-10alkyl or C2-10alkoxycarbonyl. The composition is excellent in heat resistance and forming processability.
