Abstract

Abstract Curable resinous compositions containing primary and/or secondary amine groups which are non-volatile under curing conditions and containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties which are reacted with a primary and/or secondary amine which are volatile under curing conditions are disclosed. The compositions are depositable on a substrate to form films.

Claims Analysis

Total Claims: 16
Claim 1
Independent Claim 74 words
A curable resinous composition comprising: (A) a polyamine resin containing primary and/or secondary amino groups, said resin being stable under curing conditions; and (B) a Michael adduct of an organic material containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties reacted with primary and/or secondary amines, said Michael adduct being unstable under curing conditions; said resinous composition being depositable on a substrate to form a film thereon which is curable at elevated temperatures.
Claim 2
Dependent Claim 74 words
A curable resinous composition comprising: (A) a polyamine resin containing primary and/or secondary amino groups, said resin being stable under curing conditions; and (B) a Michael adduct of an organic material containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties reacted with primary and/or secondary amines, said Michael adduct being unstable under curing conditions; said resinous composition being depositable on a substrate to form a film thereon which is curable at elevated temperatures.
Claim 3
Dependent Claim 20 words
The resinous composition of claim 1 in which a portion of the amine groups are converted to cationic salt groups.
Claim 4
Dependent Claim 12 words
The resinous composition of claim 2 which is dispersed in aqueous medium.
Claim 5
Dependent Claim 101 words
A curable resinous coating composition dispersible in aqueous medium with the aid of cationic salt groups comprising as the resinous binder: (A) a polyamine resin containing primary and/or secondary amino groups, said resin being stable under curing conditions; and (B) a Michael adduct of an organic material containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties reacted with primary and/or secondary amines, said Michael adduct being unstable under curing conditions; said resinous binder being neutralized with acid to provide said cationic salt groups and being electrodepositable on a substrate to form a film thereon which is curable at elevated temperatures.
Claim 6
Dependent Claim 101 words
A curable resinous coating composition dispersible in aqueous medium with the aid of cationic salt groups comprising as the resinous binder: (A) a polyamine resin containing primary and/or secondary amino groups, said resin being stable under curing conditions; and (B) a Michael adduct of an organic material containing alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties reacted with primary and/or secondary amines, said Michael adduct being unstable under curing conditions; said resinous binder being neutralized with acid to provide said cationic salt groups and being electrodepositable on a substrate to form a film thereon which is curable at elevated temperatures.

Claim 13
Dependent Claim 69 words
A curable resinous composition comprising a polyamine resin containing: (A) primary and/or secondary amino groups which are non-volatile under curing conditions; and (B) amine groups which are formed by reacting alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties with primary and/or secondary amines which are volatile under curing conditions; said resinous composition being depositable on a substrate to form a film thereon which is curable at elevated temperatures.
Claim 14
Dependent Claim 69 words
A curable resinous composition comprising a polyamine resin containing: (A) primary and/or secondary amino groups which are non-volatile under curing conditions; and (B) amine groups which are formed by reacting alpha, beta-ethylenically unsaturated moieties in conjugation with carbonyl moieties with primary and/or secondary amines which are volatile under curing conditions; said resinous composition being depositable on a substrate to form a film thereon which is curable at elevated temperatures.
