PURPOSE: To obtain a rubber compsn. which hardly slips and is metallic and highly fashionable, by depositing metal on a thermoplastic resin, blending the resulting lamellar lame pieces with a rubber and molding the mixture.

CONSTITUTION: A rubber molding is obtd. by blending 0.01W30pts.wt., pref. 0.1W5pts.wt. lamellar lame pieces 1 (0.1W10mm square), obtd. by depositing metal or a thermoplastic resin, with rubber 2 and molding the mixture. The lame piece 1 can be formed by depositing metallic powder on the surface of a polyester sheet. The lame piece 1 can be arbitrarily colored gold, silver, red, blue, green, etc. The rubber molding can be prepd. by blending a rubber with the lame pieces, sulfur, an accelerator, stearic acid, a filler, an activator, etc., kneading the mixture in an open roll mill or a closed kneader, forming it into a sheet having a given thickness and vulcanizing and molding it by means of a hot press or a vulcanizer.
