Claim:
A dental impression material composition comprising: (A) 100 parts by weight of the sum of (1) an organopolysiloxane containing at least two aliphatic unsaturated hydrocarbons in one molecule and (2) a polyether containing at least one aliphatic unsaturated hydrocarbon in one molecule, in a weight ratio of (1) to (2) of 1:0.01˜1:5, (B) 0.1˜100 parts by weight of an organohydrogenpolysiloxane containing at least three hydrogen atoms directly bonded to a silicon atom in one molecule, (C) 10˜500 ppm, based on the sum of (A) and (B), of a silicone-soluble platinum compound, (D) 10˜800 parts by weight of an inorganic filler, and (E) 0.5˜5 parts by weight of a nonionic surfactant and/or a polyether-modified silicone oil.
