Abstract:
A method of forming a multilayer coating on a substrate, said method comprising the steps of:(a) forming a waterborne basecoat composition comprising the steps of: i) providing a pigmented toner composition comprising: water; a polyurethane resin dispersible in water; a resin selected from the group consisting of water-reducible resins and aqueous emulsion polymers, produced by a free-radical addition polymerization reaction; and at least one pigment; (ii) providing a mixing clear composition comprising a resin selected for a particular environment under which the basecoat composition is to be applied to the substrate and dried, said resin being one of an aqueous emulsion polymer produced by a free-radical addition polymerization reaction and a polyurethane resin dispersible in water; and (iii) mixing the pigmented toner composition with the mixing clear composition; (b) applying the basecoat composition to the substrate to form a basecoat layer; (c) providing a clear coat composition; and (d) applying the clear coat composition to the surface of the basecoat layer.
