Abstract
An aqueous alkyd resin coating composition, comprising (a) at least one alkyd resin as a dispersed phase; (b) an emulsifier based on styrenated phenols that have been converted into reactive surfactants by first reaction with one or more equivalents of an allyl glycidyl ether to provide pendant allyl groups and then oxyalkylated and (c) water. The invention also provides a method for preparing these aqueous alkyd resin coating compositions from solvent borne alkyd compositions.
