Abstract
A silicone resin-containing emulsion composition is based on a silicone resin-containing emulsion obtained by emulsion polymerization of a mixture containing (A) a silanol group-bearing silicone resin and (B) a radical-polymerizable vinyl monomer. The silicone resin (A) contains 30-100 mol % of T units: R.sup.1 --SiZ.sub.3, and specifically 30-80 mol % of T-2 units: R.sup.1 --Si(OH)Z'.sub.2 among other T units wherein R.sup.1 is a monovalent hydrocarbon group, Z is a OH group, hydrolyzable group or siloxane residue, and Z' is a siloxane residue, and has a number average molecular weight of at least 500. The composition has a good film forming ability and cures into a flexible film having mar, weather and chemical resistance.
