Abstract:
1. A polysiloxane obtained by conducting a hydrolysis and polycondensation reaction of a silicon compound (T) having three hydrolyzable groups, a silicon compound (D) having two hydrolyzable groups, and a silicon compound (M) having one hydrolyzable group, wherein at least one compound of said silicon compound (T), said silicon compound (D), and said silicon compound (M) has a hydrosilyl group, wherein at least one compound of said silicon compound (T), said silicon compound (D), and said silicon compound (M) has a hydrosilylatable carbon-carbon unsaturated group, wherein said polysiloxane has a hydrosilylatable carbon-carbon unsaturated group, a hydrosilyl group and an alkoxysilyl group, and has a number average molecular weight of 500 to 20,000, wherein said polysiloxane comprises a unit represented by formula (I): wherein A is an organic group having 2 to 10 carbon atoms containing a hydrosilylatable carbon-carbon unsaturated group, R wherein 0.001≦x/(v+w)≦2, 0.01≦y/(v+w)≦2, and 0.01≦z/(v+w+x+y)≦1, whereby, when w is zero, at least one of R
