A recording sheet for ink-jet printing includes a supporting substrate, at least one microporous ink-receptive coating overlying a front surface of said supporting substrate and at least one protective overcoating overlying said microporous coating. The protective overcoating includes at least one compound selected from the group consisting of polysaccharides and polyacrylamides, and fluoropolymer particles. The diameter of the fluoropolymer particles is between about 0.5 and 3 micrometers.

There is described a nanoporous receiver element for use in thermal mass transfer imaging applications. The receiver element comprises a substrate carrying an image-receiving layer comprising particulate material and a binder material. The substrate may comprise a material having a compressibility of at least 1% under a pressure of 1 Newton per mm (1 MPa). Optionally, there may be provided, between the substrate and the nanoporous receiving layer, a layer having a thickness of less than about 50 &mgr;m which is comprised entirely of a material having a compressibility of less than about 1% under a pressure of 1 MPa. Alternatively, the substrate may comprise only the material having a compressibility of less than about 1% under a pressure of 1 MPa, provided that the thickness of the substrate does not exceed about 50 &mgr;m. The image-receiving layer comprises particulate material and a binder material, has a void volume of from about 40% to about 70% and a pore diameter distribution wherein at least 50% of the pores having a diameter greater than about 30 nm have diameters less than about 300 nm and at least 95% of the pores having diameters greater than about 300 nm have diameters less than about 1000 nm.

Thermal mass transfer imaging system

A self-developing diffusion transfer photographic film unit which includes a latent image which becomes visible upon photographic processing of the film unit. The latent image is formed with a chemical compound such as an indicator dye and the visible image formed from the latent image as a result of photographic processing may be transient or permanent. Also described are diffusion transfer photographic methods.

There are described novel image-receiving elements for use in diffusion transfer photographic systems. The novel image-receiving elements include a layer capable of reducing the light-absorbing capacity of an optical filter agent. The layer comprises nonylphenoxypolyoxyethylene and polyoxyethylene stearate. Diffusion transfer photographic systems utilizing the novel image-receiving elements of the present invention exhibit substantial clearing of optical filter agents during about the first five minutes of photographic processing, enabling the viewing of the emerging image against a whiter, brighter background, and show substantially diminished haze in the film coatings.

Image-receiving elements

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: ##STR1## wherein R.sub.1 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 R.sub.2 of each monomer unit is independently selected from a hydroxy substituted alkyl group.

Image-receiving element for diffusion transfer photographic and

An image-receiving element for use in photographic diffusion transfer film units of the type wherein the image-receiving element, which includes an image-receiving layer, is designed to be removed, or 'peeled-apart', from a photosensitive element after exposure and development have been carried out. The image-receiving element includes a strip-coat layer comprising a hydrophilic colloid, such as gum arabic, and an aluminum salt which overlies the image-receiving layer and significantly reduces striations and/or haze and facilitates the separation of the image-receiving element from the remainder of the film unit subsequent to diffusion transfer photography.
