PURPOSE: The titled composition, obtained by incorporating an organopoly siloxane consisting of specific units with polyvinyl alcohol (PVA), etc., and a photosensitizer in specific amounts and emulsifying the resultant mixture, capable of being easily coated, having a long pot life and capable of giving films having improved water resistance, etc. n CONSTITUTION: A photo-setting silicon emulsion composition obtained by incorporating (A) 99W1pts.wt. organopolysiloxane having one or more mercaptoalkyl group-containing siloxane units expressed by formula I [R 1 is alkylene; R 2 is (substituted) monofunctional hydrocarbon group; a is 0W2] and vinyl group- containing siloxane units expressed by formula II [R 3 is (substituted) monofunctional hydrocarbon; b is 0W2; c is 1W3] is the molecule and having 10W1,000,000cSt viscosity with (B) 1W99pts.wt., preferably 1W20pts.wt., polyvinyl alcohol and/or cellulose derivative, e.g. methyl cellulose, (C) 0.005W10pts.wt. photosensitizer and (D) water. n COPYRIGHT: (C)1986,JPO&Japio |
