Abstract

PURPOSE:To obtain the high-density and pure black color images free from change in image tone owing to the change in developing temperature and developing solution pH by combining the respectively specific diazo compounds, yellow color coupling components and blue color coupling components. CONSTITUTION:The three components, of the diazo compound of formula I (R is alkyl of C1-5, R1, R2 are respectively saturated (unsaturated), alkyl, aralkyl,cycloalcyl, or R1, R2 may form heterocycles with C bonding with these, X is anion), the blue color coupling agent of formula II [R2 is H, -(CH2)n-OH(n is 2-4) or formula III, R5, R6 are alkyl, R5, R6 can form heterocycles with bonding N, R4 is H, alkoxy of C1-4, halogen] and the yellow color coupling agent of formula IV are combined to prepare the photosensitive layer forming solution together with other additives such as stabilizers, saponin, etc. This solution is coated on copying original paper, etc., and is then dried, whereby the copying material is produced.
