Abstract:
1. A film-forming organopolysiloxane emulsion composition comprising (A-3) 100 parts by weight of the condensation reaction product of a hydroxy-terminated organopolysiloxane represented by the general formula (I) with an organopolysiloxane comprising trialkylsiloxy and silicate units and having silanol groups, represented by the compositional formula (II) and silica having silanol groups on its surface: wherein R 1 is a monovalent organic group of 1 to 20 carbon atoms, hydroxyl or hydrogen, and n is a positive number of 2 to 5,000, wherein R 2 is a monovalent organic group of 1 to 20 carbon atoms, hydroxyl or hydrogen, a, b and c are positive numbers in the range: 0.1≦a≦0.7, 0≦b≦0.5, 0.3≦c≦0.7, and a+b+c=1, (B) 1 to 50 parts by weight of an emulsifier, and (C) 25 to 20,000 parts by weight of water.
