Title:
METHOD OF FORMING PHOTOGRAPHIC IMAGE VIA DYE DIFFUSION TRANSFER AND PHOTOGRAPHIC MATERIAL ADAPTED THEREFOR
Document Type and Number:
Japanese Patent JPS54126535
Kind Code:
A
Abstract:
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 at a pH below 3.
