A concentrated dampening water composition for lithographic printing comprises a) 0.1 to 10% by weight of a hydrophilic polymeric compound having a film-forming ability; b) 0.01 to 15%, by weight of a pH buffering agent; c) 5 to 80% by weight of a water-miscible organic solvent having a boiling point of not less than 140.degree. C. and whose 1% by weight aqueous solution has a surface tension of not more than 60 dynes/cm; d), 0.05 to 10% by weight of a compound, for instance, represented by the ...

A solvent system has been found which improves the blotting time smearfastness and smudge for ink-jet inks. Two solvents work in conjunction with each other: 2-methyl-1,3-propanediol and methyl pentanediol. These two solvents work in combination to improve printability of inks, especially pigment-bases inks that contain latex polymers. Such ink-jet inks also include typical vehicle adjuncts.

An ink, which contains at least one dye of formula (1): wherein A and A' each independently represent an aryl group or a monovalent heterocyclic group; B and B' each independently represent an arylene group or a divalent heterocyclic group; X.sub.1 represents a divalent linking group; n1 is 0 or 1; and at least one of A, B, A', and B' is a heterocyclic group.

An ink jet ink composition comprising water, a humectant, and a polyvalent transition metal complex of 8-heterocyclylazo-5-hydroxyquinoline.

A process for coloration of a substrate comprising applying thereto means of an ink jet printer a composition comprising a medium and a compound of Formula (1): ##STR1## wherein: A is optionally substituted aryl; B is optionally substituted arylene; and R.sup.1 and R.sup.2 are each independently H or optionally substituted alkyl. Also claimed are novel compounds, compositions and ink-jet cartridges for use an ink-jet printer and substrate printed with an ink-jet printer.

An object of the present invention is to provide an electroless displacement gold plating solution, an additive for use in preparing the plating solution, and a metal composite material obtained by treatment with the plating solution. The electroless displacement gold plating solution contains a water-soluble gold compound, a complexing agent, and a water-soluble silver compound, and optionally a water-soluble thallium compound, a water-soluble lead compound, a water-soluble copper compound or a...

A process for printing textile fiber materials in accordance with the ink-jet printing process, wherein the fiber materials are printed with an aqueous ink comprising a) at least one reactive dye of formulae (1a) to (1i) as indicated herein and b) 1,2-propylene glycol or N-methyl-2-pyrrolidone. The process is especially suitable for printing cellulosic fiber materials. The prints obtained have good fastness properties while having a high color yield.

This invention provides an water-base ink achieving high print quality on plain, recycled, and coated paper, glossiness on glossy paper, as well as well-balanced gas fastness, and an water-base ink set which exhibits low light source dependence with regard to the colors of resultant printed matter. This invention is an water-base ink comprising a pigment, a surfactant and/or a penetrating organic solvent, and water, wherein the pigment is a copper phthalocyanine pigment substituted with eight or...

An ink set having a yellow ink containing at least one yellow dye, a magenta ink containing at least one magenta dye, and a cyan ink containing at least one cyan dye, wherein an oxidation potential of the magenta dye and an oxidation potential of the cyan dye are each higher than 0.8 V (vs SCE), and an inkjet recording method using the ink set.

The ink set for ink jet recording of the present invention, which exhibits a high recorded image quality, an excellent image preservability (heat stability, light fastness, oxidation resistance) and little change of color balance with time, and an ink jet recording method using same, and which comprises a plurality of inks containing a dye, a water-miscible organic solvent and water, wherein the ink set comprises at least yellow, magenta, cyan, black and dark yellow inks, and the dark yellow ink...
