摘要:
A photographic paper material comprising:(1) a support comprising a paper substrate with a synthetic resin film provided on both sides thereof;(2) a hydrophilic colloid layer containing a white pigment on one side of the support (1); and(3) a light-sensitive silver halide emulsion layer on the hydrophilic colloid layer (2),wherein the white pigment content of the hydrophilic colloid layer (2) is at least about 68% by weight.
摘要:
There is described a water-resistant paper support for photographic purposes with at least one coating which is hardened by electron beams, wherein the resin layer forming the coating contains acrylated or methacrylated phosphoric acid with a ratio of acrylate or methacrylate groups to acid groups of 1:2 to 2:1, or itaconic acid, and wherein this acrylated or methacrylated phosphoric acid or the itaconic acid in the resin mixture forming the coating amounts to 1 to 15 weight %, and preferably 4 to 10 weight %, relative to the entire mixture, and the acrylated or methacrylated phosphoric acid possesses an average molecular weight of 400 to 600.
摘要:
In a base for a photographic sensitive material comprising a polyolefin coated paper, the improvement which comprises a layer of an ionomer of an .alpha.-olefin and an .alpha.,.beta.-ethylenically unsaturated carboxylic acid between the surface of the paper and the polyolefin coating.
摘要:
A polyolefin layer carried on at least one surface of a polyolefin resin coated paper for use as a photographic paper support, contains a titanium oxide composition comprising 20-60 parts by weight of a rutile-type titanium oxide and 40-80 parts by weight of an anatase-type titanium oxide per 100 parts by weight of the titanium oxide composition. Such polyolefin resin coated paper is excellent in hiding power, resolving power, light resistance, whiteness, fading resistance, etc.
摘要:
A photographic element which comprises a resin film or resin coated paper support having superimposed thereon a layer of a composition comprising a copolymer containing therein the moiety of the general formula (I) ##STR1## wherein R.sub.1 and R.sub.2 each is a hydrogen atom or an alkyl group having 1 to 12 carbon atoms.
摘要:
Leuco dye compositions containing a compound of the formula: ##STR1## wherein m = 0 or 1: Ar is an arylene or lower alkyl substituted arylene radical;R.sub.1 and R.sub.2, which may be the same or different, are lower alkyl or hydroxyalkyl groups, or ##STR2## R.sub.3 is H, lower alkyl, benzyl, R.sub.4, or ##STR3## R.sub.5 is H, a C.sub.3 -C.sub.6 alkyl group, an aryl group, ##STR4## wherein n=2-6; and R.sub.6 is a lower alkyl group or an aryl group. Where m = 1, the formula represents a colorless leuco compound; where m = 0, the formula represents the yellow dye derivative of the leuco. These compounds are particularly useful in photosensitive compositions.
摘要:
New polymers and copolymers containing silver and/or copper, useful e.g. in manufacturing dialysis and filtration membranes, ion exchangers, light sensitive layers, catalysts and hydrophilic coatings, are prepared from copolymers or polymer mixtures containing both nitrile groups and strong acidic groups, by bringing them in contact with monovalent silver or copper ions or with their mixtures. Silver and/or copper are attached to nitrile groups by secondary valences, thus forming complex compounds. The probable formulae of the complex groups are: --CN.Ag.sup.+ or perhaps --CN.Ag.sup.+.NC-- and --CN.Cu.sup.+ or perhaps --CN.Cu.sup.+.Cu.sup.+.NC-- , the complex cations forming polymeric salts with strong acidic groups of the same or of an adjoining macromolecule, to which all said nitrile and strongly acidic groups are attached as substituents.
摘要:
A photopolymerizable element containing a self-supporting, reinforced floor is useful for preparing relief images such as those used, for example, in the printing industry. Selfsupporting, reinforced floor is provided by incorporating a reinforcing material (e.g., a fabric) within one stratum of the photopolymer element and subsequently flashing the side containing the reinforcing material with actinic radiation resulting in polymerization of the stratum which contains the reinforcing material.
摘要:
A dimensionally stable photographic paper is prepared by applying a photosensitive coating to a bleached softwood kraft fiber paper substrate containing from about 30 to 90 percent glass fibers. The paper base is prepared by adding from about 30 to 90 percent glass fiber to a bleached softwood kraft fiber pulp suspension just prior to passing the pulp through a paper making machine. The photographic paper of the instant invention has particular utility under conditions of high humidity.
摘要:
THE INVENTION CONCERNS A POLYOLEFIN SURFACE TREATED WITH A COATING OF AN ACIDIC COMPOSITION WHICH COMPRISES AQUEOUS SILICA SOL, AN ACID STABLE WATER INSOLUBLE FILM FORMING MATERIAL, SURFACE AGENTS TO KEEP THE FILM FORMING MATERIAL AS A STABLE SUSPENSION IN THE COMPOSITION, AND AN ACID. THE COMPOSITION IS COATED ONTO THE POLYOLEFIN AS AN AQUEOUS COMPOSITION AND DRIED. THE TREATMENT RENDERS THE POLYOLEFIN SURFACE ADHERENT TO, FOR EXAMPLE, PHOTOGRAPH EMULSION, PRINTING INKS AND ADHESIVES.
