Abstract

512,914. Photographic light-sensitive materials. KODAK, Ltd. (Eastman Kodak Co.). March 21, 1938, No. 8618. Addition to 438,960. [Class 98 (ii)] The unsaturated light-sensitive organic substance of the photo-mechanical resist according to the parent Specification has a yellow colour and the light-sensitive layer contains a violetdye in such proportions that the resist has a blue-green colour so that correct exposure may be judged by inspection. Dyes referred to are the bases of the triphenylmethane violets, such as methyl violet base, ethyl violet base, and crystal violet base. A resist described contains dicinnamyl acetone, pale kauri-resin, ethylmethyl ketone, toluene, benzylalcohol, and crystal violet base. The resist may be coated on metal.
