PURPOSE:To obtain the subject composition having improved coating properties and hot stamping properties, excellent in decoration properties and suitable for, e.g. a monolithic molding of a key top of a keyboard and a stem thereof by blending a polyoxymethylene resin with a specified mound of a specified polyester copolymer. CONSTITUTION:With (A) 50-97wt.% polyoxymethylene resin, (B) 3-50wt.% polyester copolymer having 2000-50000, preferably 5000-30000 number-average molecular weight composed of one or more alcohol components (e.g. ethylene glycol or propanediol) selected from 2-12C aliphatic diols and one or more acid components (e.g. oxalic acid or malonic acid) in which 20mol% or more, preferably 30-80mol% components are selected from 4-8C aliphatic dicarboxylic acids is blended. |
