Abstract

PURPOSE:To obtain a black image, by using a specified 2-hydroxy-3-naphthoamide as a coupling component. CONSTITUTION:A diazo copying material is prepared by coating a support with a photosensitive soln. contg. a diazo compd. and a coupling component represented by the general formula (R is 1-4C straight chain or branched chain alkyl) together with a binder, silica, acid, etc. In the formula, R is preferably methyl, ethyl, propyl, butyl, isobutyl, or the like, this coupler of (A) develops black for itself, but the color tone developed varies somewhat due to diazo compds. used, so other couplers can be used properly to adjust tone.

。Conventionally, in order to obtain black color in diazo type copying materials, black color is obtained by mixing a coupler that develops a blue color, a coupler that develops a yellow color, and a coupler that develops a red color. Since the speeds do not match completely, the color may turn reddish-black or reddish-black depending on the developing conditions.
