Abstract
1,236,422. Photochromic materials and uses thereof. CANON K.K. 15 Feb., 1968 [20 Feb., 1967; 31 May, 1967; 19 June, 1967; 2 Aug., 1967; 16 Aug., 1967], No. 32491/70. Divided out of 1,236,421. Heading C4S. Stable photochromic images (i.e. images which are not removed by exposure to actinic radiation) are produced by image-wise exposing a photochromic material to produce a temporary image and then treating the image with an alkaline material. Specified alkaline materials are sodium and potassium hydroxide, ammonia, alkylamines, potassium and sodium cyanide and Br÷nsted bases. The stable image can be converted to a temporary image by treatment with an acid such as acetic, benzoic, hydrochloric, nitric or a Lewis acid. Specified photochromic materials are spiropyrans, anils and semicarbazones optionally with p-nitrophenol or the materials set out in Specification 1,236,421.
