Abstract
Provided is a polylactic acid resin composition obtained by adding a carboxylic acid amide and a carboxylic acid ester each of which has at least one polar group in a molecule to a polylactic acid resin reacted with a (meth)acrylate compound. Also provided is a polylactic acid resin molded article which is a molded article obtained by molding the polylactic acid resin composition, manufactured by setting a mold temperature to a glass transition temperature of a polylactic acid resin plus 20° C. or higher and a melting point thereof minus 20° C. or lower, at the time of injection molding the polylactic acid resin composition. Thus, a resin composition in which a moldability is improved at a temperature at which a polylactic acid resin is crystallized, and a molded article therefrom are provided.
