Abstract:
An oven-drying, water dilutable coating material comprising: (A) at least one polyhydroxyl functional resin selected from the group consisting of water-dilutable acrylate resin dispersions and water-dilutable oil-free polyester resins containing urethane groups which resins are water-dilutable after neutralisation; (B) an amino resin at least partially etherified with a monoalcohol; (C) a basic neutralizing agent; (D) water; and (E) a cross-linking catalyst which is the water-insoluble non-ionically blocked reaction product of one or more strong organic or inorganic acids, and at least one compound selected from the group-consisting of a monoepoxide, a diepoxide, and a lactone, wherein the neutralizing agent (C) present in the coating material has already substantially escaped from the film at temperatures at which the ester bonds of said reaction product (E) are cleaved.
