PURPOSE:To enhance cleanability by incorporating a specified silicone type comb-shaped graft polymer in resin particles. CONSTITUTION:The silicone type comb-shaped graft polymer to be added to the resin particles that are dispersed into a surface layer is obtained by copolymerizing, preferably, the modified silicone of the condensation raction product of the silicone represented by formula I with the compound represented by formula II, with a compound having a polymerizable functional group. In formulae I and II, each of R1-R5 and R11 is alkyl or aryl optionally substituted by halogen; n is a positive integer; each of R8-R10 is H, halogen, alkyl, or aryl; X is halogen or alkoxy; and m is 1, 2 or 3. The graft polymer is added to the resin particles, preferably, in an amount of 0.1-10 wt.%, thus permitting cleanability to be enhanced. |
