<p>Coating films are prepared by exposing to oxygen, particularly at ambient temperatures, a composition comprising (a) a film-forming material comprising moieties of an ethylenically unsaturated fatty acid containing at least two ethylenically unsaturated groups and (b) a strong acid which is fully dissociated in water. Suitable filmforming materials are oil-modified alkyd resins and suitable acids are alkyl/aryl sulphonic acids. Curable compositions and polymeric products, optionally modified with nonautoxidisable polymerisable materials, are also provided.</p> |
