Patent number: 4399241Abstract: Provides new and improved water-reducible coating compositions and methods of making them. Three preferred processes are disclosed. These differ in the manner of incorporating and chemical nature of an extender polymer.Broadly, the process of the invention is one for forming an aqueous dispersion of a fluent resinous composition ofa. a mixture in an organic solvent of(i) an ionizable graft polymer of an epoxy resin and an addition polymerized resin, the addition polymerized resin being bonded to aliphatic backbone carbon atoms of the epoxy resin by carbon-to-carbon bonds, and(ii) an extender resin;b. an aqueous vehicle, andc. an ionizing agent;the ionization present from said combined components being sufficient to establish the components as a dispersion in the aqueous vehicle, and then addition polymerizing a quantity of addition polymerizable monomer, under addition polymerizing conditions, in said aqueous dispersion, the aqueous dispersion serving as a vehicle therefor.Type: GrantFiled: March 21, 1980Date of Patent: August 16, 1983Assignee: SCM CorporationInventors: Vincent W. Ting, James T. K. Woo, Richard M. Marcinko
