| abstract | 632,402. Photographic stripping film and paper. GENERAL ANILINE & FILM CORPORATION. July 14, 1947, No. 18693. Convention date, July 20, 1939. [Class 98 (ii)] In a photographic stripping film or paper having a temporary support secured by an adhesive layer to a permanent support carrying a light-sensitive emulsion, the adhesive comprises a substance, the viscosity of which is decreased and the solubility in water of which is increased by acid or neutral thiosulphate fixing solutions, such substance being a vegetable mucilage or pecto-cellulose, e.g. alginic, tangic and laminaric acids and their salts (particularly sodium and ammonium salts), and pectin. The adhesive layer may also contain spreading agents (e.g. sulphonated carboxylic acid amides) and hygroscopic agents (e.g. aqua resin or glycerol). As shown, a temporary support 1 is successively coated with a subbing layer 2, an adhesive layer 3 from a composition containing sodium alginate, oleyl-N-methyltauride, glycerol, alcohol, and water, a cellulose nitrate or acetate permanent support 4, a subbing layer 5, and an emulsion layer 6. Ammonium alginate may be used as the adhesive and aqua resin as the hydroscopic agent, or the adhesive layer may be formed from an aqueous-alcoholic solution of pectin, or an aqueous solution of sodium or ammonium alginate and pectin. The adhesive layer may contain as an antihalation dye Acid Magenta- or Tartrazine. |
