Abstract

The present invention provides compositions and method of using an aldimine oxazolidine compound having the formula: ##STR1## wherein: R.sub.1, R.sub.2, R.sub.3, R.sub.4, R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are, individually, a hydrogen atom, a methyl or methylol group, an ethyl or ethylol group, a straight chain or branched chain alkyl or alkanol group, a cycloalkyl group, or an aryl group, including any of the above groups substituted by nitro, halogen, thiol and amino functional groups, such that when R.sub.5, R.sub.6, R.sub.7 and R.sub.8 are hydrogen atoms, R.sub.3 and R.sub.4 are not hydrogen atoms, further, R.sub.7 and R.sub.8 cannot simultaneously be hydrogen atoms; m and n are integers of one to three, and m+n is between two and four; and X is a covalent bond between the nitrogen atom of the aldimine group and the nitrogen atom of the oxazolidine group or an (m+n-valent methylene group, ethylene group, straight chain or branched chain alkylene group, cycloalkylene group, or arylene group, including any of the above X groups substituted by nitro, halogen, thiol and amino functional groups. The aldimine oxazolidine compounds are useful for improving the physical properties and improving the pot life of coatings.
