Abstract
Thermosetting composition is excellent in storage stability, useful as one component thermosetting composition, gives cured products having excellent chemical properties, physical properties and weathering resistance and is favorably utilized in coating compositions, ink, adhesive and molded plastics. The thermosetting composition comprises a compound having in the molecule two or more carboxyl groups blocked by a vinyl ether compound, a vinyl thioether compound or a hetero compound having a vinyl type double bond and oxygen or sulfur as the hetero atom, a compound having two or more reactive functional groups which can form a chemical bond with the blocked carboxyl compound by heating and optionally a thermal latent acid catalyst. The blocked carboxyl group of the first compound and the reactive functional group of the second compound may be comprised in the same molecule.
