摘要:
An apparatus for producing amorphous particle dispersions of high-melting microcrystalline solids in a continuous process. The apparatus comprises a pump, two heat exchangers, a back-pressure valve and conduits connecting them, whereby it is possible to make aqueous dispersions of particles whose melting points are above 100.degree. C.
摘要:
Photographic assemblages, elements, receiving elements and cover sheets are described employing a novel neutralizing layer comprising a cross-linked polymer having recurring units of an N-(alkoxy-methyl)acrylamide, an acrylic acid and an alkyl acrylic ester. The need for a separate cross-linking agent is eliminated.
摘要:
A method of transferring a pigmented image, comprising the steps of: providing a donor element bearing an inkjet printed image containing one or more heat transferable pigments selected from the group consisting of A. 2-(N-methylcarbamyl)-4-(4-N,N-di-ethylamino-phenylimino)-1,4-naphthoquinone; B. 2-(N-methylcarbamyl)-4-(4-N,N-di-ethylamino-2-methylphenylimino)-1,4-naphthoquinone; C. 1-phenyl-3-N,N-dimethylamino-4-(4-N,N-diethylaminobenzylidene)-pyrazoline-5-one; D. N-ethyl-N-benzyl-3-acetamido-4-(3-methyl-4-cyanoisothiazol-5-ylazo)-aniline; E. N-(2-((2,6-dicyano-4-methylphenyl)azo)-5-(diethylamino)phenyl}methanesulfonamide; F. N-(2-((2,6-dicyano-4-methylphenyl)azo)-5-(dipropylamino)phenyl}methanesulfonamide; and contacting the donor element with an image receiving element; and transferring the heat transferable image to the image receiving element by applying heat to the donor element.
摘要:
A process for making ink jet inks, comprising the steps of: (A) providing an organic pigment dispersion containing a pigment, a carrier for the pigment and a dispersant; (B) mixing the pigment dispersion with rigid milling media having an average particle size less than 100 .mu.m; (C) introducing the mixture of step (B) into a high speed mill; (D) milling the mixture from step (C) until a pigment particle size distribution is obtained wherein 90% by weight of the pigment particles have a size less than 100 nanometers (nm); (E) separating the milling media from the mixture milled in step (D); and (F) diluting the mixture from step (E) to obtain an ink jet ink having a pigment concentration suitable for ink jet printers.
摘要:
Photographic assemblages and processes are described wherein a stripping layer is employed to enable an image-receiving layer to be separated from the rest of the assemblage after processing. Each side of the stripping layer has a hydrophilic layer immediately adjacent thereto, only one of which contains particulate material substantially insensitive to light and in a volume percentage of about 5 to about 75 percent of the hydrophilic material-particulate material mixture, so that upon separation, substantially all of the stripping layer will remain with the portion of the assemblage having the hydrophilic layer containing the particulate material.Transparencies or prints which are less bulky can thereby be obtained from integral assemblages.
摘要:
Photographic assemblages and processes are described wherein a certain stripping agent is employed to enable an image-receiving layer to be separated from the rest of the assemblage after processing. The stripping agent comprises a straight chain alkyl or polyethylene oxide perfluoroalkylated ester or perfluoroalkylated ether, and preferably has the following formula: ##STR1## wherein R.sup.1 is an alkyl or substituted alkyl group having from 1 to about 6 carbon atoms or an aryl or substituted aryl group having from about 6 to about 10 carbon atoms; ##STR2## R.sup.3 is H or R.sup.1 ; n is an integer of from about 4 to about 20; andx and y each independently represents an integer of from about 2 to about 50, andz represents an integer of from 1 to about 50.Less bulky black-and-white or color prints or transparencies can thereby be obtained from integral assemblages. Materials from the discarded layers may also be recycled.
摘要:
Two-sheet diffusion transfer assemblages, photographic elements and dye image-receiving elements are described wherein an overcoat layer is present on the photographic element or the dye image-receiving element superposed thereon. The overcoat layer comprises either silica or an ionic polyester in a hydrophilic colloid which prevents spontaneous delamination during the lamination period, yet permits satisfactory peel-apart afterwards.
摘要:
Photographic elements, two-sheet diffusion transfer assemblages containing such elements, and dye image-receiving elements are described. The photographic element comprises a support, a neutralizing layer, a timing layer, a vinylidene chloride polymeric layer, a polymeric primer layer, and at least one silver halide emulsion layer having a dye image-providing material associated therewith. The vinylidene chloride polymeric layer and the polymeric primer layer prevent unwanted transfer of portions of the emulsion layer to a receiver when the receiver and photographic element are peeled apart. The polymeric primer layer can be either a particular ionic vinyl polymer or a particular ionic polyester.
