PURPOSE:To obtain a polyacetal resin composition, improved in its coating properties and printability without impairing excellent characteristics of a polyacetal resin by blending the polyacetal resin with a specific functional group-containing (meth) acrylate-based copolymer. CONSTITUTION:A polyacetal resin composition is obtained by blending (A) 100 pts.wt. polyacetal resin with (B) 1-55 pts.wt., preferably 5-50 pts.wt. copolymer, prepared by copolymerizing (B1) 5-80wt.%, preferably 10-60wt.% amino group-containing (meth)acrylate [e.g. aminoethyl (meth)acrylate] expressed by the formula (R<1> to R<3> are H or methyl; (n) is the average number of mol of added alkylene oxide and is 0-100) with (B2) 10-95wt.%, preferably 20-80wt.% polyoxyalkylene group-containing (meth)acrylate [e.g. polyoxyethylene mono(meth)acrylate] and (B3) 0-85wt.% copolymerizable other monomers (e.g. styrene) and having 1000-300000, preferably 5000-250000 weight-average molecular weight. |
