Multilayer coatings having at least one base coating containing pigments and at least one transparent top coating are applied from coating compositions on the substrates and cured together. The coating composition contains:

Coating composition containing cross-linked microparticles

Process for preparing a multilayer coating

A method of making a polyester or alkyd resin composition containing acrylic microgels comprises preparing an aqueous microgel emulsion of an acrylic resin which is crosslinked with a multifunctional crosslinking agent. The water from the emulsion can be removed by coagulation and/or azeotropic distillation with an organic solvent in which the microgel is insoluble and which forms an azeotrope with water. The resulting dehydrated microgel can be incorporated into a polyester or alkyd resin. Alternatively, the acrylic microgel emulsion can be incorporated into a water reducible alkyd resin.

Polyester or alkyd resin composition containing acrylic microgels

Cross-linking agents are produced by reacting an ester of a di- or poly-carboxylic acid with a molar excess of ammonium hydroxide, thereby forming a di- or polyamide, which in turn is then methylolated and etherified with a lower alkanol. These products are cross-linkers for resins such as alkyds, oil-free polyesters, acrylic which can be either acid or hydroxy functional, phenolics, epoxies or melamines.

Etherified methylol polyamide crosslinking agent, process for producing

A method of making an acrylic microgel resin which comprises preparing an aqueous microgel emulsion of an acrylic resin which is crosslinked with a multifunctional crosslinking agent, removing water from the emulsion by coagulation and/or azeotropic distillation with an organic solvent in which the microgel is insoluble and which forms an azeotrope with water, and incorporating the thus dehydrated microgel into an acrylic resin which has been prepared by solution polymerization in organic solvent.

Acrylic resin-acrylic microgel compositions

A caprolactone-modified acrylic polymer comprising the product obtained by polymerizing a mixture of vinyl monomers, including at least one such monomer containing a --COOH and/or --OH group, with caprolactone.
