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: 10
Claim 1
Independent Claim
102 words
A method of coating an electrically conductive surface serving as a cathode which comprises passing electric current between said cathode and an anode immersed in an aqueous dispersion of an electrodepositable curable resinous composition, comprising as the resinous binder: (A) a polyamine resin containing primary and/or secondary amino groups, said polyamine 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 cationic salt groups.
Claim 2
Independent Claim
102 words
A method of coating an electrically conductive surface serving as a cathode which comprises passing electric current between said cathode and an anode immersed in an aqueous dispersion of an electrodepositable curable resinous composition, comprising as the resinous binder: (A) a polyamine resin containing primary and/or secondary amino groups, said polyamine 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 cationic salt groups.
Claim 3
Dependent Claim
19 words
The method of claim 1 in which the polyamine resin is a poly(amine-amide) having a terminal primary amine group.
Claim 4
Dependent Claim
23 words
The method of claim 1 in which the polyamine resin is the reaction product of an epoxy-containing resinous material and a primary amine.
Claim 5
Dependent Claim
27 words
The method of claim 1 in which the polyamine resin is the reaction product of an epoxy-containing resinous material and a polyamine containing ketimine-blocked primary amine groups.
Claim 6
Dependent Claim
29 words
The method of claim 1 in which (B) is formed from reacting an organic polyol with acrylic or methacrylic acid followed by reaction with a primary and/or secondary amine.
Claim 7
Dependent Claim
30 words
The method of claim 1 in which (B) is formed from reacting an epoxy-containing resinous material with acrylic or methacrylic acid followed by reaction with a primary and/or secondary amine.
Claim 8
Dependent Claim
30 words
The method of claim 1 in which (B) is formed from reacting a polymeric polyol with an N-alkoxymethyl-containing acrylamide or methacrylamide followed by reaction with a primary and/or secondary amine.
Claim 9
Independent Claim
96 words
A method of coating an electrically conductive surface serving as a cathode which comprises passing electric current between said cathode and an anode immersed in an aqueous dispersion of an electrodepositable curable resinous composition, comprising as the resinous binder 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 polyamine resin being neutralized with acid to provide cationic salt groups.
Claim 10
Independent Claim
96 words
