A water-soluble coating composition based on a binder which can be dissolved or diluted in water consisting of pre-crosslinked silicone elastomer copolymer particles with an organopolymer shell and a process for its preparation

摘要

Pre-crosslinked silicone elastomeric copolymer particles with organopolymer shells are used as ingredients to form a water soluble coating composition based on a binder that can be dissolved or diluted in water.;The silicone elastomer particles contain (a) a compound represented by the general formula (R₂SiO_2/2)_x(R'SiO_3/2)_y(SiO_4/2)_z(Where x = 5 to 99.5 mol%, y = 0.5 to 95 wt%, and z = 0 to 30 mol%) and 5 to 95 wt%;b) from 5 to 95 wt% of an organopolymer shell of a mono or polyethylenically unsaturated monomer, based on the total weight of the copolymer, wherein R is an alkyl or alkenyl radical having 1 to 6 carbon atoms, , Aryl radical or substituted hydrocarbon radical.
