Abstract:
1. A resin composition comprising from 70 parts by weight to 99 parts by weight of a polylactic acid resin and from 1 part by weight to 30 parts by weight of a polyacetal resin relative to 100 parts by weight of the total of the polylactic acid resin and the polyacetal resin, said polylactic acid resin and said polyacetal resin being miscible with each other and said polyacetal resin being a polyacetal homopolymer obtained through polymerization of, as an essential starting material, formaldehyde or trioxane, or a polyacetal copolymer consisting essentially of oxymethylene units and containing at most 15% by weight of oxyalkylene units with from 2 to 8 neighboring carbon atoms in the backbone chain, and the formaldehyde content being smaller than 500 ppm relative to the polyacetal resin.
