ABSTRACT OF THE DISCLOSURE A fabric, or article made from fabric, woven from fine thread strands made of, at least in part, photochromic compounds which change color when exposed to a source of ultraviolet light. The photochromic thread strand may be interwoven with a second thread strand devoid of any photochromic compound. The fabric thus produced can exhibit patterns of areas containing photochromic compound threads and other areas containing threads (not containing photochromic compounds) such as cotton, polyester, nylon threads and the like. The invention requires the forming of fine gauge thread which is thinner than heretofore proposed for purposes of embroidering and the like. In another aspect of the invention, the article is a fashion accessory or item used in forming a fashion accessory made of, at least in part, a photochromic compound which changes color when exposed to a source of ultraviolet light. The fashion accessory thus produced can exhibit a color change over the entire extent of its body or only in regions containing a photochromic compound, with other areas not containing photochromic compounds and thus not changing color. The invention concerns a molded plastic article or the coating of solid or flexible articles containing the photochormic compound.
