The present invention is directed to novel coating compositions. In particular, the present invention is directed to polyuroxy low VOC coating compositions. The compositions may be applied wet on wet with a suitable basecoat/clearcoat or single-stage topcoat composition.

Epoxy-urethane imine and hydroxyl primer

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

A method for reducing the volatile organic content of coating compositions wherein first, the ketimine of acetone is formed by reacting acetone and a ketimine having the formula ##STR1## wherein n is 1 to 4, R.sub.1 and R.sub.2 may be alkyl aryl, cycloaliphatic or substituted alkyl, aryl, or cycloaliphatic group. R.sub.1 and R.sub.2 may be the same or different, with the proviso that R.sub.1 and R.sub.2 are not both CH.sub.3. R.sub.3 is an aliphatic, aromatic arylaliphatic or cycloaliphatic group, which may also contain O, N, S or Si. The ketimine of acetone is subsequently reacted with at least one isocyanate functional crosslinking resin.

Method for reducing volatile organic content of coating compositions

Coating Compositions are disclosed which may be ambient cured and are especially useful in refinish paint compositions. The Coating Compositions comprise at least one hydroxy functional resin, at least one isocyanate functional resin and a aldimine or ketimine.
