Patent number: 5536817Abstract: A modified gelatin is disclosed wherein part of the free carboxyl groups is replaced by modifiers having more acid end-standing groups chosen from --SO.sub.3 M, --OSO.sub.3 M, --SSO.sub.3 M, ---OPO(OH).sub.2, --OPO(OH)(OR.sup.2), --PO(OH).sub.2, --PO(OH)(OR.sup.2).In a preferred embodiment such a modified gelatin is incorporated in a DTR photographic material which after processing can serve as a lithographic printing plate. Thanks to the more hydrophilic character of the modified gelatin the differentiation between printing and non-printing areas is improved and toning at printing start-up is reduced.Type: GrantFiled: August 30, 1995Date of Patent: July 16, 1996Assignee: AGFA-GEVAERT, N.V.Inventors: Eddy Michiels, Piet Kok, Johan Loccufier, Frank Michiels, Ludo Van Rompuy

Patent number: 5512413Abstract: The present invention provides an imaging element comprising on the same side of a support in the order given a base layer, a light sensitive layer containing a silver halide emulsion and a surface layer comprising physical development nuclei characterized in that said base layer and/or said light-sensitive layer comprises gelatin being hardened with a divinylsulfonyl hardener such that the time needed to completely brake down said base layer, light sensitive layer and surface layer using an aqueous solution of 0.14% by weight of NaOCl at 25.degree. C. is between 1000s and 1600s. A lithographic printing plate can be obtained with such imaging element according to the silver salt diffusion transfer process and exhibits an improved printing endurance.Type: GrantFiled: June 6, 1995Date of Patent: April 30, 1996Assignee: AGFA-Gevaert N.V.Inventors: Lode Deprez, Eddy Michiels

Patent number: 5162180Abstract: The present invention relates to a xeroprinting process, in particular a xeroprinting process comprising the following steps:(a) image-wise exposing to actinic radiation an electrostatic master having a photopolymerizable conductive layer to selectively polymerize and thereby increase resistivity in exposed areas of the layer;(b) forming a latent image of electrostatic charge by charging the master by corona discharge;(c) reversal developing the latent electrostatic image by depositing toner particles in the non-exposed areas of the layer;(d) transferring the toner image to another substrate and subsequent fusing;(e) resetting the process by cleaning and discharging the electrostatic master.According to a preferred embodiment the reversal development is effected by means of a development electrode inducing charges in the photopolymer plate opposite to the initial electrostatic image, and by means of dry electrophotographic toner.Type: GrantFiled: October 18, 1990Date of Patent: November 10, 1992Assignee: Agfa-Gevaert, N.V.Inventors: Luc H.

Patent number: 4820608Abstract: The present invention provides a dye diffusion transfer imaging process comprising transferring image-wise by diffusion an acid dye to an image-receiving layer incorporating a non-polymeric phosphonium mordanting agent and a copolymer latex comprising free weak acid groups as a stabilizer for the mordanting agent, wherein the image-wise transfer of said acid dye is performed in the presence of a heterocyclic compound corresponding to one of the following general formulae I, II, and III: ##STR1## wherein: Y represents the non-metallic atoms needed to complete a saturated or unsaturated 5- or 6-membered heterocyclic nucleus, which may carry a fused-on aromatic ring system, and M represents hydrogen, an alkali metal atom, a quaternary ammonium group, or a negative charge forming an inner salt with a quaternized nitrogen atom of the heterocyclic compound. The invention also provides an image receptor element for dye diffusion transfer imaging processes comprising a support and such image-receiving layer.Type: GrantFiled: October 21, 1987Date of Patent: April 11, 1989Assignee: AGFA-Gevaert, N.V.Inventors: Daniel A.
