Sulfonimide cure catalysts are used with aminoplast crosslinking agents and resins capable of reacting with aminoplast crosslinking agents to prepare heat curable compositions capable of crosslinking to form coatings and articles. Liquid or solid curable compositions may be prepared. Solid sulfonimide catalysts used in combination with solid glycoluril type crosslinking agents are well suited for powder coating systems containing hydroxy- and carboxy-functional resins.

Novel aminoplast anchored UV stabilizers are provided. Compared to unanchored stabilizers, the anchored stabilizers disclosed herein have increased compatibility with coating resins and have reduced volatility due to higher molecular weights resulting from anchoring. A process for preparing the anchored stabilizers by the reaction of unanchored stabilizers with alkoxymethylated aminoplasts in a sulfuric acid medium is also provided. The unanchored stabilizers include 2-(2-hydroxyaryl)benzotriazoles, 2-hydroxybenzophenones, 2-(2-hydroxyaryl)-4,6-diaryl-1,3,5-tri-azines, salicylic acid derivatives, 2-hydroxyoxanilides, and blocked derivatives thereof as well as mixtures of two or more stabilizers. The aminoplasts include alkoxymethylated derivatives of glycolurils, melamines, and benzoguanamines.

A monomeric alkoxymethylated aminoplast crosslinking agent derived from a m-TMI/melamine 1:1 adduct and a process for its preparation is provided. The process comprises contacting melamine with M-TMI, contacting the adduct formed with formaldehyde, and contacting the hydroxymethylated adduct with an alcohol such as butanol. A curable composition comprising the monomeric aminoplast crosslinker and a polyfunctional active hydrogen-containing material is also provided. An improved method of coating using the curable composition to produce cured films or objects is also provided.

A copolymer of a TMI/amino compound 1:1 monoadduct with ethylenically unsaturated comonomers is provided, as well as a process for producing the same. Such copolymers in and of themselves may find use as aminoplast crosslinking agents, or can readily be modified thereto. Curable compositions can be formulated from the crosslinker alone or in combination with polyfunctional active hydrogen compounds, which can be cured to produce crosslinked films and objects.
