摘要： A new method to produce photographic images is provided which comprises(a) imagewise exposing a photographic assembly which contains at least during the silver halide developing step, in order optionally a supercoat layer, at least one silver halide emulsion layer, a layer containing a modifiable image substance and a photobase, there being optionally one or more interlayers between each of said components(b) treating the exposed photographic assembly with an aqueous processing bath so as to provide in the silver halide emulsion layer or layers a solution or dispersion of an image substance modifying/silver halide developing compound (dymodev compound), thereby to develop the latent silver image in the silver halide emulsion(s), and(c) in the non-latent image areas allowing the dymodev compound to diffuse in a counter-imagewise manner from the silver halide emulsion layer(s) to the layer containing the modifiable image substance and there to modify reductively the image substance. Depending on the dymodev compound and modifiable image substance combination closen it is possible to obtain either a negative or a positive image.

摘要： A photographic dye diffusion transfer process is provided which operates by imagwise release of a dye.The dye diffuses to a receiving layer and is mordanted there to give a dye image. The dyes are released from a compound of the formula D--E--F--BAL by reductive cleavage.D is a group which contains the residue of diffusible dye, BAL is a ballasting group which renders the compound containing it substantive to the layer in which it is present, D and E being joined by any type of chemical bond and E and F represent a single or double bond system which links D and BAL and which has a reduction potential above -200 mV measured against a standard hydrogen electrode at a pH of less than 3 and which bond can be reductively cleaved at a pH of less than 3 by a reducing agent which is able to act as a pH below 3.
摘要翻译：提供通过成像释放染料来操作的照相染料扩散转移方法。染料扩散到接收层，并且染色在那里以产生染料图像。染料通过还原性裂解从式D-E-F-BAL的化合物中释放出来。 D是含有可扩散染料残基的基团，BAL是使其含有它的化合物与其存在的层相当的压载组，D和E通过任何类型的化学键连接，E和F表示单键或双键系统，其连接D和BAL并且具有在小于3的pH下相对于标准氢电极测量的-200mV以下的还原电位，并且该键可以通过还原在pH小于3下被还原性裂解能够作为pH低于3的药剂。
