    摘要: Azo dyes corresponding to the formula (I): ##STR1## wherein R.sup.1 represents a releasable group, R.sup.2 represents H, halogen or sulphonyl, R.sup.3 and R.sup.4 represent H or groups not capable of chelate formation, and Q represents a group for completing a phenyl or naphthyl group,combine with nickel ions to form stable azo dye-metal complexes which have advantageous spectral properties. They are therefore particularly suitable for the production of highly light-fast magenta images, e.g. by the ink jet process, in which they may be used directly in the form of colored inks, or by the dye diffusion transfer process, in which they are released imagewise from suitable dye-releasers in the course of development and transferred to a dye-receptive layer.
