    Abstract: A planographic printing plate prepared by electrostatic exposure and development and carrying a hydrophobic deposit from such development in the image areas thereof is hydrophilized by treatment with an aqueous solution containing a polymeric compound having in the recurring units thereof an amino salt and/or quaternary salt group the polymer compound being free of long chain hydrocarbon groups. Preferred hydrophilizing compounds are polyamines having aliphatic linkages between the amino groups and polyvinyl compounds having hydrogen-containing heterocyclic side groups.

    Abstract: A LIGHT-SECSITVE MATERIAL COMPRISING A SILVER HALIDE EMULSION LAYER AND CONTAINING A MERCURY(II) CHELATE OF A (POLY) AMINO-(POLY)CARBOXYLIC ACID IN THE FORM OF THE ACID OR A WATER-SOLUBLE SALT IS DESCRIBED. THE CHELATC EXERSTS A STABILIZING AND FOG-INHIBITING ACTION UPON THE LIGHTSENSITIVE MATERIAL WITHOUT CAUSING APPRECIABLE DESENSITIZATION.

    Abstract: The method of rendering silver halides developable in photographic elements by treating the elements with a processing liquid comprising a tin(II)chelate of a (poly)amino(poly)carboxylic acid in acid form or in the form of a water-soluble salt is described. The aforesaid tin(II)chelates have good chemical fogging action forming developable specks in a light-sensitive silver halide material and remain stable in alkaline solutions permitting their incorporation in a developer solution eliminating need of an independent processing bath.

    Abstract: Photographic materials comprising a support, a light-sensitive silver halide emulsion layer on said support and thereover a hydrophilic colloidal protective coating is described. The photographic material will include resorcin in the emulsion layer and a poly-N-vinyl lactam or polyvinyl lactone in the emulsion layer or in the protective surface coating. The surface coating will include silica particles and a polycarbocyclic aromatic sulphonic acid or water-soluble salt thereof. The photographic material is free or substantially free from milkiness or cloudiness normally associated with photographic materials comprising resorcin, polyvinyllactam or polyvinyllactone, and silica.

    Abstract: A printing plate of the type which is prepared by coating a metal supporting surface with a photo-insolubilizable polymer, exposing the coating to a light image, developing the exposed coating by treatment with a liquid dissolving the unexposed areas only of the coating so that the exposed areas remain as a resist layer on the metal surface, and etching the metal surface with the resist layer thereon by means of an aqueous etching liquid therefore, is given increased resistance in the exposed regions to the attack of the etching liquid by incorporating into the developing liquid a hydrophobizing agent which is either an organic compound containing at least one fluorine substituted alkyl group of an organic silane or siloxane compound containing at least one alkyl or aryl group linked to at least one of its silicon atoms, the hydrophobizing agent also containing a reactive group capable of chemically reacting with the photoinsolubilizable polymer. The polymer preferably includes active hydrogen atoms after insolubilization and preferred chemically active groups in the hydrophobizing agent are acid anhydride, isocyanate, epoxy, and acid chloride groups.
