A composition comprising the following components: n100 parts by weight of an organopolysiloxane (A), n0.1 to 30 parts by weight of a crosslinking agent (B), n50 to 1,000 parts by weight of a polyvinyl alcohol homopolymer or copolymer (C), n0 to 5 parts by weight, as an active ingredient, of a catalyst (D), n100 to 100,000 parts by weight of water (E), and n0.1 to 100 parts by weight of a surfactant (F), wherein component (A) is an organopolysiloxane (A3) having at least two alkenyl groups and represented by the following formula (3):n nwherein each R 1 may be same or different and is a group having 1 to 20 carbon atoms selected from the group consisting of alkyl groups, alicyclic groups, and aryl groups, whose hydrogen atoms bonded to the carbon atoms may partly be replaced with a halogen atom or a cyano group, R2 is an alkenyl group and X 3 is the group represented by the following formula:n nwherein a3, b3, c3, d3 and e3 are such numbers that the organopolysiloxane (A3) has a viscosity at 25 degrees C of from 0.05 to 500 Pa· s, and b3, c3,d3 and e3 may be zero, and α and β are integers of from 0 to 3 and ncomponent (B) is an organohydrogenpolysiloxane (B3) having at least three SiH groups per molecule. |
