Definitions

  • ABSTRACT A support for an image-receiving material for the silver salt diffusion transfer process having on a paper base, in order, a polyolefin resin layer and a polyvinyl butyral layer containing a fluorescent brightening agent, is disclosed.
  • the present invention relates to a support for an image-receiving material for the silver salt diffusion transfer process.
  • animage is formed on the imagemetal sulfides which are slightly soluble in water, metal selenides, heavy metals or colloidal noble metals are 7 usually used.
  • a support such as a paperyfilm, metal plate, etc., to prepare an imagereceiving material
  • An image-receiving material containing silverdepositing nuclei with especially high activity is useful as a photographic material for high speed silver salt diffusion transfer photography.
  • silver-depositing nuclei having an especially high activity can be obtained by mixing a water-soluble metal salt with a water-soluble sulfide in an aqueous dispersion of an especially fine silicon dioxide to prepare a precipitate 'of a waterinsoluble metal sulfide (which functions as silv'erdepositing nuclei).
  • the aqueous dispersion of the silicon dioxide containing silver-depositing nuclei obtained in this way is coated on a support sheet and dried to obtain an image-receiving material, from which positive prints with a good image quality can be obtained.
  • the support for the imagereceiving material it is required that l the support be water-proof, (2) the surface thereof should be smooth superior to cellulose acetate in that they are highly water-impermeable and stretch only to a small extent on heating.
  • the surface thereof should be smooth superior to cellulose acetate in that they are highly water-impermeable and stretch only to a small extent on heating.
  • a fluorescent brightening agent it is difficult to increase the whiteness thereof even by the addition of a fluorescent brightening agent to the resin.
  • polyethylene or polypropylene is laminated on a sheet ofpaper by melt extrusion coating, but, those fluorescent brightening agents which can resist this melting temperature have such an insufficient brightening effectthat is difficult to obtain the whiteness necessary for a support for an image-receiving material for the silver salt diffusion transfer process.
  • the surface treated with a" corona discharge will again become hydrophobieon aging, and hence it will become diffi cultto coat an image-receiving layer thereon.
  • An object of this invention is to provide a novel photographic support.
  • Another object is to provide a support especially suitable for an image-receiving material for the silver salt diffusion transfer process.
  • Another object is to provide a water-proof and'lustered support for an image-receiving material for the silver salt diffusiontransfer process.
  • a further object is to provide a support having a high whiteness for an image-receiving material for the silver salt diffusion transfer process.
  • an image-receiving material for the silver salt diffusion transfer process having, in order, a polyolefin resin layer and a polyvinyl butyral resin layer containing a fluoresent brightening agent thereon on a paper base.
  • the polyolefln resin layer in this invention is as a major component composed of polyolefin such as polyethylene.
  • polypropylene, copolymers of ethylene and propylene etc. which are film-forming, adhesive to a sheet of paper and are water-proof. All types of polyethylene, polypropylene and copolymers are suitable. Generally, those having an average molecular weight ranging from about 10,000 to 100,000 are preferred. Where copolymers of ethylene and propylene are'used, those having a propylene content ranging from about 0.1 to 30 molar percent are preferred.
  • the polyolefin resin layer is usually coated using a melt extrusion method.
  • the polyolefin layer should be coated in a thickness necessary to maintain the water-proof property and the luster of the surface thereof, and, usually is in a thickness of more than 5 microns after drying.
  • the polyvinyl butyral layer is coated on the polyolefin layer usually as a solution for example as a solution of the polyvinyl butyral in a solvent such as benzene, toluene, chloroform, ethylene glycol mono butyl ether, n-butanol, ethyl acetate, methyl acetate, xylene, methanol, ethylene glycol mono methyl ether, cyclohexanone, o-dichlorobenzene, diacetone alcohol, dioxane, glacial acetic acid, mono chlorobenzene, solvent naphtha, cresylic acid, methylbutanol, methylpentanol, and the like.
  • a solvent such as benzene, toluene, chloroform, ethylene glycol mono butyl ether, n-butanol, ethyl acetate, methyl acetate, xylene, methanol,
  • the polyvinyl butyral layer should be coated in a thickness necessary to obtain sufficient whiteness and, usually in a thickness of more than 0.5 micron. If the polyvinyl butyral layer is coated in a thickness thinner than 0.5 micron, sufficient whiteness in the composite support cannot be obtained.
  • a thick resin layer i.e., the thickness of the resin layer formed of the polyolefin resin layer and the polyvinyl butyral resin layer does not cause any deleterious effects on the its photographic properties.
  • too thick of a coating is not preferred because it increases the total thickness of the support, makes the support heavy and consumes extra polyolefin, polyvinyl butyral and solvent, and hence the production costs are increased.
  • the polyolefin layer and the polyvinyl butyral layer are suitably coated in a thickness of less than about 0.1 mm and about 0.05 mm respectively.
  • Suitable fluorescent brightening agents which can be contained in the polyvinyl butyral layer are those which are soluble in organic solvents for example, alcohols such as methanol, ethanol, propanol, butanol, etc.; ketones such as acetone, ethyl methyl ketone, etc.; esters such as methyl acetate, ethyl acetate, etc.; ethers such as ethylene glycol mono methyl ether, ethylene glycol mono ethyl ether, etc.; aromatic hydrocarbons such as benzene, toluene, xylene, etc.; and aliphatic hydrocarbons such as chloroform, cyclohexanone, tetrachloromethane, methylene chloride, etc..
