    Abstract: A composite coating of a water-borne basecoat and an epoxy-acid clearcoat has improved performance characteristics of reduced yellowing or reduced tendency to chip through the formulation of the composite coating and the process for its application. The process comprises applying to the substrate a film-forming composition to form a basecoat and applying to the basecoat an epoxy-acid clear film-forming composition to form a transparent topcoat over the basecoat. The basecoat is a coating composition comprising a polymeric film-forming resin, aminoplast crosslinking agent and a pigment wherein the crosslinking agent is a partially or fully alkylated aminoplast and has a lower or higher imino content. The lower imino content promotes reduced yellowing of the clearcoat and the higher imino content promotes improved chip resistance when the pigment of the water-borne basecoat reduces yellowing effects. The transparent topcoat, or clearcoat, has an epoxy film forming resin and a polycarboxylic acid crosslinking agent.

    Abstract: The invention concerns coating agents and their use in preparing single or multi-coat coatings. The coating agents comprise an aqueous mixture of: I) 99 - 70 wt. % of a mixture of: A) 50 to 100 wt.% of one or a plurality of binders, at least some of which carry ionic groups; B) 0 to 50 wt.% of one or a plurality of crosslinking agents for binders A), at least some of which can carry ionic groups, the ionic groups present having the same charge as component A); and II) 1 to 30 wt.% of one or a plurality of binders (component C) which can be mixed with one another by the binders of component A) both at the storage temperature and at the curing temperature of the coating agents, and which carry ionic groups whose charge is the opposite of the charge of the ionic groups of component I), the wt.% in each case being relative to the resin solids weight, and the portions of components I) and II) being adapted to each other such that 0.5 to 70 % of the number of charges of the ionic groups of I) are neutralized by the charges of the ionic groups of II); and III) conventional paint additives and/or pigments and/or fillers, and optionally one or a plurality of solvents conventional in paints.

    Abstract: A method for reducing the molecular weight of aminoplast compounds, the aminoplast compounds obtained thereby, and coating compositions containing said aminoplast compounds are provided. The reduced molecular weight aminoplasts are obtained by reacting
    (a) an aminoplast compound, having a total number (y) of reactive substituents on the amino nitrogens of the aminoplast, where y= (E x M) and E = equivalents per mole of aminoplast and M= total number of moles of aminoplast, wherein the reactive substituents are selected from the group consisting of -NH, alkylol, alkoxy, alkoxyalkyl, and mixtures thereof and (b) at least one carbamate compound selected from the group consisting of unsubstituted and substituted primary carbamate compounds, unsubstituted and substituted secondary carbamate compounds and mixtures thereof, in the presence of primary or secondary alcohols, at temperatures under 150°C, and at pressures ranging between atmospheric pressure and 20 atm pressure, to form a functionalized aminoplast compound, wherein at least one and up to (y-1) of the amino substituents on the aminoplast are substituted with the carbamate functionality.
