Claim 1

THE METHOD OF TEMPORARILY PROTECTING THE SURFACE OF A VULCANIZED RUBBER ARTICLE WHICH NORMALLY IS OBJECTIONABLY DEFICIENT IN RESISTANCE TO SURFACE ATTACK BY OZONE AGAINST SUCH ATTACK WHICH COMPRISES APPLYING THERETO A COATING OF A SOLUTION CONSISTING ESSENTIALLY OF AN ELASTOMER SELECTED FROM THE GROUP CONSISTING OF POLYCHLOROPRENE, COPOLYMERS OF FROM 55 TO 85% COMBINED ALIPHATIC CONJUGATED DIOLEFIN HYDROCARBON AND CORRESPONDINGLY FROM 45 TO 15% COMBINED ACRYLONITRILE, COPOLYMERS OF FROM 20 TO 60% COMBINED ALIPHATIC CONJUGATED DIOLEFIN HYDROCARBON AND CORRESPONDINGLY FROM 80 TO 40% COMBINED ACRYLATE ESTER SELECTED FROM THE GROUP CONSISTING OF ALKYL AND CHLOROALKYL ACRYLATES, AND COPOLYMERS OF FROM 50 TO 80% COMBINED ALIPHATIC CONJUGATED DIOLEFIN HYDROCARBON AND CORRESPONDINGLY FROM 50 TO 20% COMBINED MONO-VINYL PYRIDINE, A SOLUBLE, FUSIBLE PHENOL-FORMALDEHYDE RESIN COMPATIBLE WITH SAID ELASTOMER, THE AMOUNT OF SAID RESIN BEING EQUAL TO FROM 5 TO 100 PARTS PER 100 PARTS OF SAID ELASTOMER, AND A VINYL RESIN SELECTED FROM THE GROUP CONSISTING OF POLYVINYL CHLORIDE AND COPOLYMERS OF A MAJOR PROPORTION OF VINYL CHLORIDE AND A MINOR PROPORTION OF POLYMERIZABLE MONOMER, THE AMOUNT OF SAID VINYL RESIN BEING EQUAL TO FROM 2 TO 5 TIMES THE WEIGHT OF SAID ELASTOMER, DISSOLVED IN A VOLATILE ORGANIC SOLVENT TO A TOTAL SOLIDS LEVEL OF FROM 5 TO 30%, SAID SOLUTION BEING FREE FROM CURING AGENTS FOR SAID ELASTOMER AND CURING AGENTS FOR SAID PHENOLFORMALDEHYDE RESIN, EVAPORATING SAID SOLVENT TO FROM A THIN, CONTINUOUS, OZONE-PROTECTIVE, TACKFREE, LUSTROUS, MARK-RESISTANT, FLEXIBLE FILM WHICH IS READILY STRIPPABLE FROM SAID SURFACE, AND SUBSEQUENTLY STRIPPING SAID FILM FROM SAID SURFACE.
