Abstract: Described is A method of decreasing the formaldehyde content in an organic paint containing composition comprising the steps of adding to the organic paint containing composition an effective amount of an organic nitrogen containing formaldehyde fixating agent. Suitable nitrogen fixating compositions are nitro parafins, nitro alcohols, amino alcohols, and nitrogen heterocyclic compounds containing from 5 to 8 members in a ring and further containing from 1 to 3 nitrogen atoms per ring and optionally including oxygen atoms present in the ring.

Abstract: an electrophoretic coating composition bath based on styrene-maleic anhydride copolymer is disclosed. The electrophoretic coating composition bath comprises a dispersion in water of an at least partially neutralized, partial ester of styrene-maleic anhydride copolymer, a cross-linking agent for the styrene-maleic anhydride copolymer, e.g., melamine-formaldehyde resin, and a neutralization agent for said styrene-maleic anhydride copolymer. The styrene-maleic anhydride copolymer has an about 1:1 to 4:1 molar ratio of styrene to maleic anhydride. The copolymer has a molecular weight of about 500 to 4,000 and is esterified to an acid number in the range of about 20 to 350. The copolymer is esterified to about 25 to 125% half-ester and neutralized to about 20 to 100% based on the esterified resin. The neutralizing agent suitable for use in the present invention can be for example, alkali metal hydroxides, ammonia, lower aliphatic amines, and lower aliphatic hydroxy amines.
