Hydrophilic layers adjacent a stripping layer for diffusion transfer
assemblages
摘要:
Photographic assemblages and processes are described wherein a stripping layer is employed to enable an image-receiving layer to be separated from the rest of the assemblage after processing. Each side of the stripping layer has a hydrophilic layer immediately adjacent thereto, only one of which contains particulate material substantially insensitive to light and in a volume percentage of about 5 to about 75 percent of the hydrophilic material-particulate material mixture, so that upon separation, substantially all of the stripping layer will remain with the portion of the assemblage having the hydrophilic layer containing the particulate material.Transparencies or prints which are less bulky can thereby be obtained from integral assemblages.
