Definitions

  • This invention relates to photographic film elements. More particularly it relates to transparent photographic film elements which have a polyvinyl acetal color formersilver halide dispersion anchored to the support by means of a substratum composed of a copolymer of vinylidene chloride, an acrylic ester and itaconic acid. Still more particularly it relates to such elements wherein the film base is composed of an oriented highly polymeric linear ester of a dicarboxylic acid and a dihydric alcohol. The invention also relates to a method of preparing such elements.
  • An object of this invention is to provide photographic film elements wherein a polyvinyl acetal color formersilver halide dispersion is firmly anchored to a film base.
  • Another object is to provide such elements which have improved dimensional stability.
  • 'A further object is to provide such elements wherein the film base is composed of an oriented highly polymeric ester of a dicarboxylic acid and a dihydric alcohol. Still other objects will be apparent from the following description of the invention.
  • polyvinyl acetal color formers which are hydrophilic to water-soluble in character, as the binding agent for silver halide grains has been disclosed in a number of patents in the past six years. It has been difficult, however, to obtain adequate anchorage between thin layers composed of such dispersions and the usual types of hydrophobic film base. This is particularly true of film base composed of highly polymeric esters of dicarboxylic acids and dihydric alcohols and especially films composed of polyethylene terephthalates. These polyvinyl acetal dispersions do not have good adherence to the conventional gelatin sublayers which have been used for many years in anchoring colloid silver halide emulsion layers to hydrophobic films.
  • the polyvinyl acetal silver halide dispersion layer has been applied, or (2) by first applying to the layer of copolymer a'thin layer of a hydroxyl polymer which contains a plurality of recurring intralinear groups as polymer-forming units, said polymers being water-soluble to hydrophilic in character.
  • the adherence of the latter intermediate substratum can also be improved by heatingthe coated film base to a temperature of at least 70 C. before applying the silver halide dispersion. This heating step, however, can be applied after thepolyvinyl acetal color-.former-silver halide dispersion has been coated onto the layer of hydroxyl polymer.
  • Synthetic hydroxyl polymers of the water-soluble and hydrophilictype include polyvinyl alcohol and its partially substituted water-soluble lower fatty acidesters, lower alkyl esters, and lower acetals.
  • Polyvinyl alcohol is a tough, white, amorphous material. water. The more highly polymerized varieties are soluble in hot water and the medium or lower polymers aresol uble in cold water. They are usuallyprepared by hydrolysis of polyvinyl esters, such as polyvinyl acetate,
  • the solutions used to coat the substratum of the synthetic hydroxyl polymer, free from color former nuclei may contain a coagulating agent, e. g., boric acid or a boric acid ester of a polyhydric alcohol, e. g., an ester prepared by reacting an alcohol. such as ethylene glycol, diethylene glycol, triethylene glycol, erythritol, sorbitol, mannitol, etc., with boric acid or a mixture of boric acid and borax, by heating the admixture to C. to C'. A copious evolution of Water occurs.
  • the resulting products are viscous syrups or resins of a colloidal nature and have a high molecular weight and complex structure.
  • boriborates They are readily soluble in Water but are substantially insoluble in hydrocarbons but probably hydrolyze to the boric acid and glycol in water. Their preparation is described in United States Patents 1,953,741, 2,223,349, 2,223,948, 2,223,949, and 2,224,011. These compounds have been referred to as boriborates:

  • a superpolymer e. g
  • the solvent should have only a mild solvent actiononthe base so that it will not appreciably dissolve the film base but have a superficial effect and merely soften or bite into the surface of the base.
  • the substrata composed of a vinyl alcohol polymer and/or the polyvinyl acetal color former-silver halide dispersion coatings are formed by coating them onto the layer of vinylidene chloride copolymer.
  • the useful ethylenically unsaturated esters which may be used in the copolymers are the alkyl esters of acrylic and methacrylic acids having from 1 to 18 carbon atoms in the alkyl group- (e. g., methyl methacrylate, ethyl methacrylate, butyl methacrylate, octyl methacrylate, n-dodecyl methacrylate, n-octadecyl methacrylate, methyl acrylate,

S. Patent 2,513,190.
  • the silver halide dispersion was found to have good adherence to the film base.
  • the film was exposed and processed as follows:

The resulting film was exposed and processed-as, described in Example I with similar results.
  • Examplelll A sample of a polyethylene terephthalate film base of the type used in Example .I was treatedwith a copolymer of vinylidene chloride-methyl acrylate-itaconic acid of the type used in Example I, then stretched biaxlally and coated with a solution of.the.following composition:

  • heating temperature of at least 70 C. has been referred to above the examples include higher temperatures and indeed temperatures up to 150 C. or more can be used if they do not deleteriously affect the coated layers. This can be determined visually with respect to the particular color former.
  • temperatures up to 150 C. or more can be used if they do not deleteriously affect the coated layers. This can be determined visually with respect to the particular color former.
  • the heating step may precede the application of the polyvinyl acetal color former layer.
  • the invention is not limited to the use of the specific polyvinyl acetal color formers given in the examples as many other hydrophilic to water-soluble acetals of this general type can be substituted with similar results.
  • suitable polyvinyl acetal color formers are those described in the following U. S.

  • color films for multicolor photography they will contain several superposed polyvinyl acetal color-former-silver halide emulsion layers which are so arranged and sensitized that they record different colors of the visible spectrum.
  • These color formers can be selected to yield yellow, blue-green (cyan), and magenta, etc., quinoneimine, aszomethine,
