摘要： A peel-apart type instant film unit comprising an image receiving sheet separably adhered in a heat sealing manner to a mask member which is peeled apart from the former after the development thereof. There is provided therebetween a weak sealing layer comprising an adhesive layer of a thermoplastic polymer having hydrophilic groups and a separating layer which is alkali resistant and has a good separation property relative to the adhesive layer. The weak sealing layer can provide an easy separation between the separating and adhesive layers so as perfectly to transfer the adhesive layer to the image receiving sheet to provide a fine appearance and a writeable image frame on the image receiving sheet. The mask member is made of any polyethylene compounded paper sheets and is provided with a processing liquid-resisting layer inside the weak sealing layer for the purpose of preventing the permeation of processing liquid thereto.

摘要： Colored dye diffusion images are produced using a recording material containing, on a layer support (layer element 1), a first dye absorbent layer (layer element 2), a light-sensitive element containing silver halide emulsion layers and color-providing compounds (layer element 3) and optionally a second dye absorbent layer (layer element 4), in that order. An imagewise distribution of diffusible dyes is produced in the light-sensitive element in the course of development and transferred to the first dye absorbent layer.The light-sensitive element is then decomposed by a treatment which decomposes its layers, e.g. by means of a proteolytic enzyme, but leaves the first dye absorbent layer intact. The second dye absorbent layer optionally present, which has a lower mordanting capacity than the first dye absorbent layer and serves to prevent contamination of the developer bath with diffusible dyes, is also decomposed.

摘要： A diffusion transfer photographic element composed of a photosensitive sheet, a cover sheet, and a processing composition contained in a rupturable container in such a manner that the processing composition is spread between both sheets after exposing the photosensitive sheet is disclosed. The whiteness of highlights of images obtained is improved by incorporating a graft carbon black polymer prepared by graft polymerizing a monomer to carbon black in the photographic element, in particular, in the light-shielding layer of the photosensitive sheet.The graft carbon black polymer prepared by graft polymerizing a monomer to carbon black can be uniformly dispersed in an aqueous medium and thus the photographic properties of a diffusion transfer photographic element can be improved using the graft carbon black polymer.

摘要： Image transfer photographic elements, assemblages, processes and compositions are described which employ carbon black in an opaque layer and/or alkaline processing composition, the carbon black having a deactivating compound adsorbed thereto so that dye image-providing material can diffuse through the opaque layer and/or processing composition without any substantial adsorption thereof to the carbon black, the deactivating compound being incapable of releasing any dye moiety therefrom.In a preferred embodiment, the deactivating compound has the following formula: ##STR1## wherein: (a) Ballast is an organic ballasting radical;(b) Z is ##STR2## or is part of Y; (c) G is OR.sup.1 or NHR.sup.2 wherein R.sup.1 is hydrogen or a hydrolyzable moiety and R.sup.2 is hydrogen or a substituted or unsubstituted alkyl group of 1 to about 22 carbon atoms;(d) Y represents the atoms necessary to complete a benzene nucleus, a naphthalene nucleus or a 5- to 7-membered heterocyclic ring;(e) X is a moiety which is adsorbed to the carbon black and thus retards adsorption thereto of the dye image-providing material;(f) J is a bivalent linking group which is non-cleavable by oxidation; and(g) n is a positive integer of 1 to 2 and is 2 when G is OR.sup.1 or when R.sup.2 is hydrogen or an alkyl group of less than 8 carbon atoms.Post-processing image dye diffusion is thereby lessened.
