| Claim | A high solids coating composition comprising: (a) at least one cross-linkable organic polymer, (b) at least one solvent selected from water and an organic solvent, and (c) at least one cross-linking agent, characterized by a content of (d) at least one reactive diluent of the formula: wherein: R₁ represents hydrogen, or alkyl of from 1 to 4 carbon atoms; R₂ and R₃ individually represent hydrogen, alkyl of from 1 to 2 carbon atoms; R₄ represents hydrogen, alkyl of from 1 to 10 carbon atoms, hydroxyalkyl, alkylenoxy and polyalkyleneoxy groups of from 2 to 10 carbon atoms; M represents: -R₅ (amine), -OR₅ (carbamate) or - R₅ (amino) wherein: R₅ and R₆ individually can represent hydrogen, alkyl of 1 to 10 carbon atoms, hydroxyalkyl of 2 to 10 carbon atoms,or alkyleneoxy and polyalkyleneoxy groups of from 2 to 10 carbon atoms and optionally containing one hydroxyl group; with the provisos that: (a) when R₅ is attached to oxygen it is not hydrogen, and (b) there is only one NH group or only one OH group in the molecule in addition to the OH group which may be present when R₁ is hydrogen. The coating composition of claim 1 wherein R₁ is alkyl, -preferably methyl -,R₂ and R₃ are hydrogen, R₄ is alkyl and M is R₅ which is hydroxyalky The coating composition of claims 1 or 2 wherein the reactive diluent is 2-hydroxyethyl methoxymethylene butylcarbamate or 2-hydroxyethyl N-(2-ethylhexyl)-N-methoxymethylene carbamate. The coating composition of claims 1 to 3 wherein the cross-linkable organic polymer is a member consisting of polyurethane resins, polyester alkyd resins, hydroxyl-containing epoxy fatty acid esters, hydroxyl-containing polyesters, hydroxyl-containing acrylic interpolymers and hydroxyl-containing vinyl interpolymers. The coating composition of claims 1 to 4 which further comprises a cross-linking catalyst. 2-Hydroxyethyl N-butyl-N-methoxymethylenecarbamate. 2-Hydroxyethyl N-(2-ethylhexyl)-N-methoxymethylenecarbamate. |
