Abstract

PURPOSE:To obtain the prescribed optical density of the titled dyestuff with a small amount of addition, by incorporating a specified dyestuff having a large molecular extinction coefficient in the titled dyestuff. CONSTITUTION:The titled dyestuff is shown by formula I or II wherein Za, Zb and Zc are each =CH- or =C(R2)- group, etc., R1-R5 are each H or a substituting group, etc., (n) is 1 or 2. But, one of groups R1 and R2 has Hammetts substituting constant sigmap of <=-0.41 or the total sigmap of the groups R1 and R2 is <=-0.41. The titled dyestuff may contain a prescribed metallic complex salt to improve the stability against a light or a heat. The titled dyestuff is useful for a color image forming magenta or yellow dyestuff. As said dyestuff has the large molecular extinction coefficient, the prescribed optical density of the titled dyestuff is obtd. with the small amount of addition.
