<p>Disclosed is an improved autoxidizable coating and/or impregnating composition containing: (1) from about 5% to about 75% by weight, based on the total of components (1) and (2), of a reactive non-volatile diluent monomer system comprising (a) from about 1% to about 99% by weight of monomer system of at least one member selected from the group consisting of dicyclopentenyloxyalkyl esters of a polymerizable ethylenically unsaturated monocarboxylic or dicarboxylic acid, and (b) from about 1% to about 99% by weight of monomer system of at least one member selected from the group consisting of methacryloxyalkyl esters of a drying oil, or a semi-drying oil, fatty acid; (2) from about 95% to about 25% by weight, based on the total of components (1) and (2), of a filmforming component selected from the group consisting of (a) drying oils per se, (b) alkyd resins having autoxidative functionality, (c) vinyl addition polymers with drying oil functionality, (d) film-forming binders lacking any appreciable inherent autoxidizable functionality, and -ii- (e) condensation polymers modified with acrylate or methacrylate functionality; (3) an effective amount of a polyvalent metalcontaining complex or salt that catalyzes the autoxidative curing of components (1) and (2), and, optionally, (4) a volatile oxime stabilizer.</p> |
