Toner composition for use in textile printing

The present invention relates to a xeroprinting process, in particular a xeroprinting process comprising the following steps:

Xeroprinting process using reversal development process

1. A photographic silver halide emulsion material which contains in operative contact with at least one alkali-permeable silver halide hydrophilic colloid emulsion layer a ballasted non-diffusing compound capable of releasing a diffusible dye or dye precursor corresponding to the following general formula:

Non-diffusing compounds capable of releasing a diffusible dye or dye

Photographic silver halide material containing a ballasted electron-donor precursor compound yielding by alkaline hydrolysis an electron-donor compound (ED-compound) capable (1) of donating electrons to an oxidized electron-accepting silver halide developing agent e.g. for scavenging it, said electron-donor precursor compound corresponding to the following general formula: ##STR1## wherein: R represents hydrogen or a substituent, e.g. an acyl group, which on hydrolytic removal allows the replacement of R by H,

Photographic silver halide material containing a ballasted

A photographic material for diffusion transfer photography containing a quinonoid compound, which is capable in reduced state and under alkaline conditions of releasing a dye moiety for the production of a dye image and corresponds to the following general formula (G): ##STR1## wherein: R.sup.8 is hydrogen or methyl in the 6- or 7-position (indicated by an asterisk) on the saturated adjacent ring part of the quinonoid nucleus,

Diffusion transfer material and process

Photographic color elements are described wherein one of the emulsion layers comprise a 4-phenylazo-2-pyrazolin-5-one coupler, the phenylazo group of which carries a p-alkoxy group of the formula:

Novel magenta-forming color couplers and their use in photography

A compound of the following formula and use of this compound in a photographic material and a photographic diffusion transfer process for the production of color images: ##STR1## wherein R represents a hydrogen atom or an alkyl group with 1 to 4 C atoms;
