PURPOSE:To improve permanent antistatic properties and transparency by compounding an acrylic resin with a specific transparent polyamide elastomer. CONSTITUTION:A polyamide-forming monomer contg. 50wt.% or higher caprolactam, a 6-20C dicarboxylic acid, and a polyoxyethylene glycol having a number-average mol.wt. of 800-3000 are condensed to give a transparent polyamide elastomer comprising 20-45wt.% polyamide segment and 80-55wt.% polyoxyethylene glycol segment and having a relative viscosity at 30 deg.C of 1.5 or higher and a haze value at 1mm thickness of 50% or lower. 100 pts.wt. mixture of 70-97wt.% acrylic resin with 30-3wt.% the polyamide elastomer is componded with 10 pts.wt. or lower at least one antistatic agent selected from the group consisting of a salt of an org. sulfonic acid and a salt of an org. phosphoric acid (e.g. sodidum dodecylbenzenesulfonate).
