COATING COMPOSITIONS PREPARED FROM MICHAEL ADDUCTS

摘要

A coating composition contains; A. an ungelled Michael adduct formed by reacting, under conditions sufficient to form a Michael adduct, (a) a material containing one or more primary and/or secondary amino groups; (b) a material containing at least two alpha,beta-ethylenic- ally unsaturated moieties; with the proviso that the reactants (a) and (b) are selected such that the resultant Michael adduct contains hydroxyl functionality; and B. a curing agent adapted to crosslink with the hydroxyl functionality present on the Michael adduct; said adduct being stable under the curing conditions for the coating composition. The aforedescribed coating compositions are particularly useful as anti-chip primers.
