Patent ID: 7361383

Claim:
A process for repair coating of vehicle substrates which comprises: a) applying a filler layer of a filler coating composition to a metal substrate, b) curing the resultant filler layer by irradiation with high energy radiation and c) applying a top coat layer to the cured filler layer and curing the top coat layer, wherein the liquid filler coating composition comprises A) 15-60 weight-% of at least one free-radically polymerizable binder comprising at least one free-radically polymerizable olefinic double bond, said binder having fewer than three of said olefinic double bonds per molecule, B) 40-85 weight-% of a free-radically polymerizable reactive diluent comprising at least one (meth)acrylic acid ester having an olefinic double bond, said at least one (meth)acrylic acid ester being formed by reacting (meth)acrylic acid with at least one cycloaliphatic alcohol, wherein the weight-% of components A) and B) adds up to 100 weight-%, and C) 2-10 weight-% of at least one compound having at least one phosphoric acid group and containing at least one free-radically polymerizable double bond, wherein the weight-% of component C) is relative to quantity of the entire coating composition; wherein said cured filler layer produces no edge marks when said topcoat layer is applied.
