摘要:
Radiographic silver halide materials coated onto a support contain a portion of the developer chemistry incorporated within the radiographic film. The remainder of the developer chemistry is contained in a developer solution. Use of a reflective support permits the developed materials to be viewed without a light box.
摘要:
The present invention relates to a method of reading an image, which comprises exposing a color photosensitive material having at least three photosensitive layers containing blue-, green- and red-photosensitive silver halide emulsions, respectively, on a transparent support, processing the exposed color photosensitive material at a processing temperature of 50 °C or more to form a silver image, and substantially reading the silver image.
摘要:
A photographic element comprises at least one light-sensitive layer on a support wherein the photographic element also comprises a particulate ion exchange material having an average particle size of about 0.01 to about 10 µm and comprising at least one reducing agent ionically bound to an ion exchange matrix.
摘要:
A developer for light-sensitive material capable of processing in common a negative-working light-sensitive lithographic printing plate and a positive-working light-sensitive printing plate as well as a developing agent-containing type silver halide photographic material, is disclosed. The developer comprises an alkali agent, an anionic surface active agent, an antifoggant for a silver halide photographic material, and an alkylene oxide addition product (molecular weight of from 130 to 1200) of an aromatic amine or an aralkyl amine, and has pH of the range of from 11.5 to 13.5.
摘要:
A silver halide photographic activation material is disclosed comprising a film support, on one or both sides thereof at least one gelatino silver halide emulsion layer and between said emulsion layer and said support a hydrophilic undercoat layer comprising as a binder at least 50 % of a loaded latex polymer, said latex polymer being loaded with at least one developing agent, further characterised in that water absorption during activation processing is not higher than 2.5 g per gram binder present in said material.
摘要:
A process for developing a photographic material containing on a support an image-wise exposed silver halide emulsion layer of which the silver halide is substantially silver chloride and in which the photographic material before its exposure contains already at least one silver halide developing agent in a hydrophilic colloid binder in waterpermeable relationship with the silver halide, said process containing the step of contacting the exposed photographic material with an aqueous alkaline liquid, called activator liquid, being initially substantially free from developing agent(s), said contacting being not followed by a silver complex diffusion transfer processing, characterized in that said aqueous alkaline liquid contains a primary and/or secondary amine.
