Method of preparing a coating composition

Claim 1

A METHOD OF PREPARING A THERMOSET COATING ON A SUBSTRATE WHICH COMPRISES SOLUBILIZING AN EFFECTIVE AMOUNT OF A POLYMERIC MATERIAL IN AN INERT-ORGANIC SOLVENT AND DISPERSING THEREIN A STOICHIOMETRIC AMOUNT BASED ON THE EPIRANE OXYGEN GROUPS PRESENT IN THE GLYCIDYL COMPOUND OF A POLYCARBOXYLIC ACID CROSS-LINKING AGENT AND 0 TO 90 PARTS BY WEIGHT OF A PIGMENT; SAID PIGMENT AND CROSSLINKING AGENT BEING SUBSTANTIALLY INSOLUBLE AND NON-REACTIVE IN THE ORGANIC SOLVENT AT TEMPERATURES BELOW 115*F. AND HAVING A PARTICLE SIZE OF LESS THAN 15 MICRONS; AND SUBSEQUENTLY COATING SAID DISPERSION ONTO THE SUBSTRATE AND BAKING THE COATED SUBSTRATE AT TEMPERATURES RANGING FROM ABOUT 150*F. TO 700*F. FOR A PERIOD RANGING FROM ABOUT 2 SECONDS TO 30 MINUTES; AND POLYMERIC MATERIAL PREPARED BY COPOLYMERIZING ABOUT 50 TO 85 PARTS BY WEIGHT OF AT LEAST ONE ETHYLENICALLY UNSATURATED COMPOUND SELECTED FROM THE GROUP CONSISTING OF METHYLMETHACRYLATE, ETHYL METHACRYLATE, PROPYL METHACRYLATE, ISOPROPYL METHACRYLATE, BUTYL METHACRYLATE, ISOBUTYL METHACRYLATE, VINYLBENZENE AND HYDROCARBON-SUBSTITUTED VINYLBENZENES; ABOUT 0 TO 50 PARTS BY WEIGHT OF AT LEAST ONE UNSATURATED ESTER SELECTED FROM THE GROUP CONSISTING OF A VINYL ESTER OF A SATURATED MONOCARBOXYLIC ACID, AN ESTER OF ACRYLIC ACID WHEREIN THE SATURATED GROUP CONTAINS 2 TO 18 CARBON ATOMS PER MOLECULE AND AN ESTER OF AN UNSATURATED DICARBOXYLIC ACID AND ABOUT 1 TO 20 PARTS BY WEIGHT OF A GLYCIDYL COMPOUND OF AN ACRYLIC ACID.

FOR A PERIOD RANGING FROM ABOUT 2 SECONDS TO 30 MINUTES; AND POLYMERIC MATERIAL PREPARED BY COPOLYMERIZING ABOUT 50 TO 85 PARTS BY WEIGHT OF AT LEAST ONE ETHYLENICALLY UNSATURATED COMPOUND SELECTED FROM THE GROUP CONSISTING OF METHYLMETHACRYLATE, ETHYL METHACRYLATE, PROPYL METHACRYLATE, ISOPROPYL METHACRYLATE, BUTYL METHACRYLATE, ISOBUTYL METHACRYLATE, VINYLBENZENE AND HYDROCARBON-SUBSTITUTED VINYLBENZENES; ABOUT 0 TO 50 PARTS BY WEIGHT OF AT LEAST ONE UNSATURATED ESTER SELECTED FROM THE GROUP CONSISTING OF A VINYL ESTER OF A SATURATED MONOCARBOXYLIC ACID, AN ESTER OF ACRYLIC ACID WHEREIN THE SATURATED GROUP CONTAINS 2 TO 18 CARBON ATOMS PER MOLECULE AND AN ESTER OF AN UNSATURATED DICARBOXYLIC ACID AND ABOUT 1 TO 20 PARTS BY WEIGHT OF A GLYCIDYL COMPOUND OF AN ACRYLIC ACID.
