Abstract
A process for the production of an ultra violet absorbing polymer latex is provided. The inventive process involves the emulsion polymerization of a benzotriazole- or benzophenone-containing monomer with a vinyl functional monomer in the presence of a chain transfer agent, preferably 1-dodecanethiol. The latex provides excellent long-lasting, easy to apply, difficult to remove, ultraviolet absorption properties for many different substrates, most notably fabrics. Different articles and fabrics coated, covered, laminated, and the like, with the inventive latex are also provided.
