The present invention refers to an ink jet receiving sheet for ink-jet printers comprising a support and at least one ink receiving layer, wherein said ink receiving layer comprises a binder selected from the group consisting of gelatin and gelatin derivatives and at least one saccharide derivative selected from the group consisting of mono-, oligo-, or poly-saccharides as additive agents to improve glossiness.
摘要:
A multilayer photographic element comprising at least one light-sensitive emulsion layer comprising silver halide grains dispersed in a hydrophilic colloid and at least one auxiliary hydrophilic colloid layer, said plurality of layers of different composition being simultaneously coated onto a hydrophobic support from aqueous hydrophilic colloid compositions, presents improved coating quality if at least one auxiliary hydrophilic colloid layer comprises a) an anionic surface active agent, b) at least one of betaine, N-oxide or amide surface active agent the and c) at least one of dispersed droplets of a water-immiscible high-boiling organic solvent, a vinyl addition polymer latex or a highly deionized gelatin.All the layers can be simultaneously coated from said different hydrophilic colloid aqueous compositions while maintaining a distinct layer relationship and avoiding any coating defects.
摘要:
Light-sensitive silver halide photographic element comprising a support bearing at least a light-sensitive silver halide emulsion layer and at least a protective layer being further away from the support than every silver halide emulsion layer, said protective layer containing a gelatin having a viscosity lower than 20 milliPascal per seconds in 10 weight % aqueous solution at 40.degree. C., said gelatin being hardened with a carbamoyl pyridinium salt compound having the following formula: ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group, an aryl group or an aralkyl group, or R.sub.1 and R.sub.2, together, constitute the atoms required to form a heterocyclic ring with the nitrogen atom to which they are bonded,R.sub.3 represents hydrogen atom, a halogen atom, an alkyl group, an alkoxy group, a carbamoyl group, or a ureido group, andR.sub.4 represents an alkylene group or a single chemical bond between the pyridinium nucleus and the --SO.sub.3 -- group.
摘要:
The present invention relates to a silver halide photographic material comprising a support, at least one silver halide emulsion layer coated thereon, and a hydrophilic colloid layer coated on said at least one silver halide emulsion layer, wherein said hydrophilic colloid layer comprises a combination of (a) at least one surfactant selected from the group consisting of non-ionic polyoxyethylene surfactants and anionic polyoxyethylene surfactants and (b) at least one surfactant selected from the group consisting of non-ionic perfluoroalkylpolyoxyethylene surfactants and polyoxyethylene-modified polysiloxane surfactants.
摘要:
The present invention relates to a support base for light-sensitive photographic elements. In particular, the present invention relates to a support base comprising a support having coated thereon at least two antihalation layers overcoated by a protective layer. The support base for light-sensitive photographic elements of the present invention presents an improved coating quality with a reduced formation of mottle, defined as an irregularly patterned defect due to the tendency of the coated layers to reproduce any deformation present on the support.
摘要:
A process of simultaneously applying multiple layers of hydrophilic colloidal aqueous coating compositions to a moving support with a multilayer bead coating apparatus, which comprises applying as the first layer next to the support an hydrophilic colloidal aqueous composition comprising a high molecular weight, highly deionized gelatin in which there are dispersed fine droplets of a high temperature boiling water immiscible organic solvent, and a multilayer silver halide photographic material comprising a support on which there are spread at least one silver halide photosensitive layer and at least one auxiliary layer, and said material further comprising, spread over said support under said layers, a hydrophilic colloidal layer comprising high molecular weight, highly deionized gelatin in which there are dispersed fine droplets of a high temperature boiling water immiscible organic solvent.
