Abstract

PURPOSE:To obtain the title copying material capable of forming a pure-black image of high fastness by making combined use of a specified diazo compound, a blue coupling component and a yellow coupling component. CONSTITUTION:A diazo compound (a) represented by formula I [where R is 1- 5C alkyl; each of R1 and R2 is (cyclo)alkyl or aralkyl; R1 and R2 may bond to each other to form a heterocyclic ring; and X is an anion], a blue coupling component (b) represented by formula II [where R3 is H or a group of formula III (where n is 2-4) or formula IV (where n is 2-4; each of R5 and R6 is alkyl; and R5 and R6 may bond to each other to form a heterocyclic ring); and R4 is H, 1-4C alkoxy or halogen], and a yellow coupling component (c) represented by formula V (where R5 is 1-5C alkyl) are used in a ratio of a:b:c=1:0.2-0.2-2 by mol to form a photosensitive layer on a support.
