摘要:
A light-sensitive silver halide photographic material suitable for super rapid processing is disclosed. The photographic material comprisses a support and, provided on at least one side thereof, a light-sensitive silver halide emulsion layer containing a silver halide emulsion obtained by a method comprising steps of adding an aqueous solution of water-soluble silver salt and an aqueous solution of a water soluble halide into an aqueous solution containing a protective colloid to precipitate silver halide grains, coagulating said silver halide grains together with said protective colloid by the use of a polymer coagulant, and removing a supernatant liquid containing dissolved metrials.
摘要:
A silver halide photographic material that contains a polymer including a repeating unit represented by the following general formula (I) and having a weight average molecular weight of no more than 30,000: where R 1 is a hydrogen atom or an alkyl group; Z represents the atomic group necessary to form a lactam ring, an oxazolidone ring or a pyrrolidone ring; A is a simple linkage, -CO-, -COO(CH 2 or -CONR 2 (CH 2 where R 2 is a hydrogen atom or an alkyl group, and n is an integer of 1 - 6. This photographic material experiences a minimum level of increase in fogging during rapid processing and produces image having improved sharpness and granularity.
摘要:
A polymeric surfactant being a block copolymer comprising chemically linked polymeric blocks (a) and (b), the block (a) part of said copolymer consisting of homo-or copolymerized apolar monomeric Alpha, Beta-ethylenically unsaturated compound(s), characterized in that the block (b) part of said copolymer consists of polymerized Alpha,Beta-ethylenically unsaturated monomer containing an epoxy group that has been transformed into an ionic group. The use of said surfactant as dispersing agent in aqueous dispersions and plasticizing agent in hydrophilic colloid layers.
摘要:
In farbfotografischen Aufzeichnungsmaterialien können Farbbilder mit verbesserter Dmin/Dmax-Relation erhalten werden, wenn den Silberhalogenidemulsionsschichten, denen farbgebende Verbindungen zugeordnet sind, und/ oder benachbarten nicht lichtempfindlichen Schichten ein Polymer mit wiederkehrenden Strucktureinheiten eines polymerisierten Monomers, das wenigstens eine Urethan- und/ oder eine Harnstoffgruppierung enthält, als zusätzliches Bindemittel zugesetzt wird.
摘要:
A polymer composition of excellent compatibility comprises a block copolymer containing a polyvinyl alcohol polymer unit as one constituent and a polymer unit having an ionic group as another constituent, and a protein. It is suitable, especially when the protein is gelatin, for making a photographic emulsion, microcapsules, a photosensitive material, etc.
摘要:
Elements, including radiation-sensitive elements (e.g. color photographic paper products), comprise a support having thereon a substantially crystal- and agglomeration-free hydrophilic layer. This layer comprises a hydrophilic composition comprising a hydrophilic binder and water-insoluble polymer particles dispersed therein. These particles have recurring units derived from one or more ethylenically unsaturated polymerizable monomers, and comprise from 0.5 to 10 percent, based on total monomer weight, of a hydrophobe uniformly distributed throughout the particles. Particularly useful polymer particles are those having recurring units derived from at least one monomer having a crosslinkable moiety. Particularly useful hydrophobes are optical brighteners.
