    摘要: Photographic elements, diffusion transfer assemblages and processes are described which employ a novel nondiffusible compound having a releasable pyridylazopyrazole or pyrimidylazopyrazole dye moiety. The compound contains in the ortho position of the azopyrazole moiety a metal chelating group, a salt thereof or a hydrolyzable precursor thereof, and a ballasted carrier moiety which is capable of releasing the diffusible azo dye under alkaline conditions. The dye is transferred imagewise to an image-receiving layer where it is contacted with metal ions to form a metal-complexed azo dye transfer image of excellent stability.

    摘要: Bright greenish yellow dyes of excellent color value prepared by coupling a lower alkyl anthranilate into 1-phenyl-3-carbalkoxy-5-pyrazolone and having the formula: ##STR1## WHERE R and R.sub.1 are independently lower alkyl; X is hydrogen, halogen, nitro, hydroxy, lower alkyl or lower alkoxy; Y is hydrogen, halogen, lower alkyl or nitro and a and b are integers of 1-2. This class of azo dyes, when appropriately dispersed, produces dyeings on aromatic polyester fabrics with excellent substantivity, outstanding sublimation fastness and good fastness to light. The dyes are applied to polyester, such as polyethyleneterephthalate, by carrier dyeing, pressure dyeing and thermofixation methods.
