摘要:
A printable film that contains a polymeric film substrate with a front side and a backside. The printable film contains also a light diffusion layer and an image receiving layer. The light diffusion layer is applied on the backside of the polymeric film substrate and contains inorganic particles, dispersing agents and polymeric binders. The image receiving layer is applied over the light diffusion layer on the backside of the polymeric film substrate. Also disclosed herein is the method for obtaining the printable film.

There are described novel photographic processing compositions, film units and processes for use in diffusion transfer photographic systems. More particularly, there is described a method for forming a diffusion transfer image photographic processing of diffusion transfer photographic film units in the presence of hypoxanthine and inosine. Diffusion transfer photographic systems utilizing the novel photographic element or method of the present invention exhibit substantially fewer, if any, crystals on the final image of the finished photograph post-processing.
摘要:
An image-receiving element for use in photographic and photothermographic diffusion transfer film units of the type wherein the image-receiving element is designed to be removed or "peeled-apart" from a photosensitive element following exposure and processing. The present image-receiving element comprises in sequence, a support, an image-receiving layer, and a strip-coat layer. The strip-coat layer serves to facilitate separation of the image-receiving layer from a photosensitive element after processing. The strip-coat layer comprises a copolymer including: 1) at least about 50% by weight of monomer units, the same or different, derived from an ethylenically unsaturated carboxylic acid or salt thereof, 2) at least about 15% by weight of monomer units of vinyl pyrrolidone, and 3) at least about 5% by weight of monomer units, the same or different, represented by the formula: wherein R1 of each monomer unit is independently selected from: hydrogen, a substituted or unsubstituted alkyl having 1 to 4 carbon atoms, cyano, and halogen; X of each monomer unit is independently selected from -NH- or -O-; and R2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.

Blends of poly(caprolactone) and poly(vinyl chloride) have been found to have good dye permeability. They have been incorporated into photothermographic constructions as barrier interlayers and dye-receiving layers.
摘要:
Imageable articles having dye selective interlayers comprising copolymers of styrene and vinylidene chloride are disclosed. The interlayers have sufficient permeability to be useful for constructions in which cationic dyes must be prevented from diffusing away from an image receiving layer. Additionally, the selective interlayers allow unoxidized leuco dye to be diffused away from an image receiving layer, thereby increasing print stability. Use of these interlayers in multicolor dye-diffusive imaging constructions increases image stability and color density in the final image.
摘要:
A security document containing a photograph obtained by the silver complex or dye diffusion transfer process in an image receiving layer containing light interference pigments uniformly distributed in said image receiving layer, and/or in a layer overlaying or underlying said image receiving layer, said layer(s) being present on an opaque support, characterised in that said interference pigments are composed of silicate platelets coated with either: A) a first layer of highly refractive metal oxide, and B) a second black layer essentially consisting of metallic iron, molybdenum and/or wolfram, or coated with: A) a first layer of highly refractive metal oxide, and B) a second black layer essentially consisting of carbon or metal, and C) a third layer of highly refractive metal oxide.
