    Abstract: Thermosetting liquid coating compositions, based on polymer capable of being crosslinked with nitrogen resin crosslinkers, nitrogen resin crosslinker, and blocked acid catalyst prepared from materials containing at least one oxirane functionality and a sulfonic acid and having a resistivity of at least one megohm are provided. The novel thermosetting coating compositions are particularly useful in electrostatic spraying applications.

    Abstract: The adhesion, especially wet adhesion, properties of conventional polymer latices are greatly improved by the incorporation of groups derived from the reaction of carbonyl groups with hydrazines therein. The hydrazine-modified groups can be present in any component of the polymer latex, but are advantageously part of the main polymer itself. Preferred main polymers are therefore those containing carbonyl units capable of reacting with hydrazine or a substituted hydrazine, especially copolymers of N-3-oxyhydrocarbon-substituted acrylamides such as diacetone acrylamide. Significantly improved wet adhesion properties are obtained even with very low proportions of the hydrazone-modified groups.

    Abstract: An organic solvent based composition comprising a blend of certain quantities of a partially or fully alkylated glycoluril blended with certain organic solvent dispersible non-gelled, non-self-crosslinking polymeric materials containing only certain reactive groups and catalyzed with small quantities of an acid catalyst which will cause the glycoluril derivative to crosslink with the polymeric material, when subjected to heat.
