Abstract
A silicone resin-containing emulsion composition is prepared by emulsion polymerizing a solution containing a water-insoluble silanol group-bearing silicone resin and a radical polymerizable vinyl monomer and substantially free of an organic solvent. The emulsion may further contain a film-forming assistant having a boiling point of at least 100° C. and soluble or uniformly dispersible in water. The emulsion can be coated and cured into a film having mar resistance, weather resistance, and chemical resistance.
