    摘要： A pigment-based ink composition for ink jet recording is provided which can offer prints having excellent scratch resistance and free from uneven printing. Ink jet recording is carried out using an ink composition comprising a pigment and an inorganic oxide colloid in combination. Further, the use of a recording head equipped with a nozzle plate (101), which has been treated to form a fluoropolymer-containing plating layer (104) thereon for rendering the nozzle plate (101) water-repellent, can realize printing free from the ejection of ink droplets with trajectories non-perpendicular to the print head.

    摘要： An ink jet recording method comprising the step of printing two solutions of a first solution and an ink composition is provided which, even in the case of printing on a recycled paper, can realize a good printed image, especially an image having no significant feathering and free from unevenness of printing and an image free from color bleeding. A first solution containing a polyvalent metal salt and/or a polyallylamine is used in combination with an ink composition containing an inorganic oxide colloid, and optionally an epoxy-containing compound. Specifically, the first solution is deposited onto a recording medium, and the ink composition is then deposited by ink jet printing to perform printing.

    摘要： There is provided an ink composition which can yield records possessing excellent rubbing/abrasion resistance and scratch resistance. Specifically, records possessing excellent rubbing/abrasion resistance and scratch resistance can be produced by using an ink composition comprising: an alkali-soluble copolymer; water; a colorant; and at least one member selected from the group consisting of wax, a viscosity modifier, and a wetting agent. The alkali-soluble copolymer is a copolymer, with an acid value of not more than 40, which is produced by polymerizing an ethylenically unsaturated carboxylic acid monomer and other monomer copolymerizable with the ethylenically unsaturated carboxylic acid monomer in the presence of an alcoholic hydroxyl-containing water-soluble polymer compound or a copolymerizable surfactant and has been adjusted to a pH value, at which the copolymer is soluble in water, by the addition of an inorganic base.

    摘要： It is an object of the present invention to provide an ink jet recording method and ink set with which recorded material with excellent gloss and greatly reduced gloss unevenness can be easily obtained without higher costs being entailed, the ink jet recording apparatus having to be modified or made larger, etc., and to provide an ink jet recording method with which a high-quality image can be obtained with a low gloss ratio (maximum value/minimum value) dependent on duty, as well as recorded material produced by this method. The present invention provides an ink jet recording method, in which a pigment ink composition and a clear ink composition containing a resin component are discharged to record information on a recording medium, wherein the discharge amount of the pigment ink composition and/or the discharge amount of the clear ink composition is adjusted so that the gloss will be substantially uniform over the entire recording surface of the recording medium after recording.
