PURPOSE:To obtain a marking agent which gives a print having a distinct color, a shiny gloss and excellent weatherability, and hardly discoloring by using, as the base material, a raw silicone rubber contg. a specific mica-titanium pearlescent pigment homogeneously dispersed therein. CONSTITUTION:The agent contains as the base material a raw silicone rubber (e.g one obtd. by reacting a linear siloxane polymer having alkenyl groups with a siloxane polymer having hydrogen groups) contg. a colored mica-titanium pearlescent pigment (e.g. Infinite Color, a product of Shiseido Co., Ltd.) homogeneously dispersed therein. The pigment is obtd. by coating the surface of mica with a lower titanium oxide of the formula: TiO2-x (wherein 0<=x<=1) alone or together with titanium dioxide. |
