PROBLEM TO BE SOLVED: To obtain a resin composition excellent in antistatic property and surface appearance, and useful for a covering member for protecting a light source of a lighting utensil by blending a specific polyether and an alkylsulfonic acid salt with a transparent resin in a specific ratio. SOLUTION: This resin composition is obtained by blending (A) 100 pts.wt. transparent resin such as a methacrylic resin with (B) 0.01-10 pts.wt. polyether of the formula [R<1> is H or CH3 ; (n) is a number decided by mean molecular weight thereof] having 2,000-50,000 number averaged molecular weight, (C) 0.1-5 pts.wt. compound of the formula: R<2> -SO3 M [R<2> is an 8-18C (branched) alkyl; M is an alkali metal] and (D) 0.5-20 pts.wt. white-type inorganic compound particles having 0.1-20μm weight averaged particle diameter (e.g. calcium carbonate particles and barium sulfate particles). |
