A clearcoat curable by ultraviolet radiation including at least one of A) acrylate or methacrylate monomers or mixtures thereof having from one to six free-radically polymerizable groups per molecule or B) compounds containing two or more ethylenically unsaturated, free radically polymerizable groups per molecule and mixtures thereof or mixtures of A) and B). The coating may optionally include photoinitiators, volatile organic solvent(s) and customary additives. The invention further provides a process for applying the clearcoat to a substrate. In a preferred embodiment the process according to the present invention includes low energy curing of a clearcoat applied to a substrate by means of a UV light source utilizing UVA/UVV or UVA only and involves essentially no UVB or UVC radiation.

Coating composition curable with ultraviolet radiation

Low VOC automotive paint compositions containing reactive urea/urethanes are disclosed. Clearcoat and single stage topcoat formulations are found to be especially useful according to this invention.

Paint compositions containing reactive urea/urethanes

The present invention relates to a coating composition and a pigment dispersant comprising aldimine having the formula ##STR1## wherein R.sub.1 is alkyl, aryl, cycloaliphatic or substituted alkyl, aryl, cycloaliphatic or heterocyclic group, and R.sub.2 is monomeric or polymeric aliphatic, aromatic, arylaliphatic or cycloaliphatic group which may contain O, N, S, or Si.

Aldimine based coating compositions and pigment dispersions

An intermediate clear barrier coat is composed of at least one polymer or oligomer or combination in an aqueous or organic solvent carrier. This layer is placed between a basecoat layer containing pigment and a low VOC clearcoat layer and inhibits the components of the low VOC clear topcoat from inducing a shift of color in the basecoat.
