Abstract
PURPOSE:To sharpen a visible absorption spectrum, and to make the color of the titled coupler distinct, by incorporating a specified pyrazoloazole short wavelength type mazenta or yellow coupler in the titled material. CONSTITUTION:The novel pyrazoloazole type coupler is shown by formula I, wherein R1 is H or a substituting group, X is H or a group capable of releasing by coupling reaction with the oxidant of an aromatic primary amine developing agent (A), Za, Zb and Zc are each =CH- or =C(-R2)- group, etc., one of Za-Zb binding and Zb-Zc binding is a double bond, and another of them is a single bond, R2 is H or a substituting group, R1 or R2 may be a divalent binding group. Said coupler may be a polymer binding with a main chain of said polymer through the group R1 or R2. And, the photosensitive material having a layer contg. the coupler shown by the formula (the coupler shown by formula II) is preferably developed with a developer contg. a developing agent (A).
