Abstract
A thermosetting resin composition which comprises (A-2) a vinyl polymer having at least one each of 2-oxo-1,3-dioxolan-4-yl group and a carboxyl group together on the polymer and a catalyst (B) effective for ring-opening the 2-oxo-1,3-dioxolan-4-yl group and curing said vinyl polymer, and related resin compositions.
Claims16
An aqueous thermosetting resin composition comprising an aqueous resin (W- 1) obtained by neutralizing with a basic compound part or all of the carboxyl groups of a vinyl polymer (A-2) having at least one 2-oxo-1,3-dioxolan-4-yl group and at least one carboxyl group together on the polymer, and then dispersing or dissolving the resulting neutralized polymer in water;
- and a ring opening curing catalyst (B).
An aqueous thermosetting resin composition comprising (I) an aqueous resin (W-3) obtained by dispersing in water a vinyl polymer (A-1) having at least one 2-oxo-1,3-dioxolan-4-yl group on the polymer, or an aqueous solution or aqueous dispersion (W-4) of a compound (A-3) which is different from the above (A-1) and having at least two 2-oxo-1,3-dioxolan-4-yl groups or a combination of (W-3) and (W-4);
- (II) an aqueous resin (W-2) obtained by neutralizing with a basic compound part or all of the carboxyl groups of a compound (c-2) having at least two carboxyl groups and dispersing or dissolving the resulting neutralized compound in water;
- and (III) a ring opening curing catalyst (B).
