A method for ink-jet textile printing including the steps of: (a) ejecting a pigment ink from a recording head onto a fabric, wherein the pigment ink contains at least water, a pigment and a polymer, wherein the polymer has a plurality of said chains in a hydrophilic main chain and is capable of cross-linking between the side chains by irradiation of active energy rays, and (b) forming an image by irradiation of active energy rays onto the ink ejected areas.

Method of ink-jet textile printing

An ink-jet recording method which enables recording of precise images by using a photo-curable ink and an ink-jet recording apparatus is disclosed, comprising ejecting an ink from a recording head to form ink dots on a recording medium, and exposing the recording medium to an actinic ray, wherein at least one of the timing of ejecting the ink and the rate of conveying recording medium is controlled so that the number of ink dots per unit length is greater in the sub-scanning direction than in the main scanning direction.

Ink-jet recording method

An ink-jet ink is provided which exhibits excellent ejection stability during printing and results in improved abrasion resistance of text and images formed on various recording media, as well as improved image smoothness by employing an ink-jet ink wherein in the ink jet ink incorporating at least a pigment, water, and fine polymer particles, the ink viscosity ratio &#x3b7;/&#x3b7;satisfies the conditions specified by Formula (1) below, and a recording method using the same:0.8&#x3c;&#x3b7;/&#x3b7;&#x3c;5.0&#x2003;&#x2003;Formula (1)wherein &#x3b7;represents the viscosity of an ink-jet ink at 25&#xb0; C. which incorporates a viscosity retarding material or incorporates at least a pigment, water, and fine polymer particles, while &#x3b7;represents the viscosity of the above ink at 25&#xb0; C. in which water equivalent to 10 percent by weight of the entire ink weight has been evaporated.

Ink-jet ink and recording method using the same

An ink-jet ink comprising Component (A), Component (B), and Component (C), wherein a content of Component (A) is 20-60% by weight, a content of Component (B) is 10-50% by weight, and when the content of Component (A) is 100% by weight, the total content ratio of a class of glycol, a class of polyol, and glycerin is 0-20% by weight, and a surface tension of the ink-jet ink is 18-27 mN/m; wherein Component (A) is 1,3-dimethyl-2-imidazolidinone or &#x3b3;-butyrolactone, Component (B) is water, and Component (C) is a pigment.

Ink-jet ink and ink-jet recording method

An ink-jet recording sheet comprising a substrate having thereon a porous layer formed by a process comprising the steps of:

Method for preparing an ink-jet recording sheet with a constant and a falling drying rate

An ink jet recording sheet comprising a non-water absorptive support having thereon an ink absorptive layer comprising polyvinyl alcohol, a cationic polymer, and a compound containing a zirconium or aluminum atom other than zirconium oxide and aluminum oxide, wherein a surface pH of the ink absorptive layer is 4 to 6 measured 30 minutes after receiving a water based ink of pH range 6 to 9 jetted from an ink jet printer in an amount of 20 ml/m .

Ink jet recording sheet

An ink jet recording sheet comprising a support having thereon a porous ink absorptive layer comprising inorganic particles, polyvinyl alcohol, at least two cationic polymers having a quarternary ammonium salt group in the molecule, and a compound containing a zirconium atom or an aluminum atom other than zirconium oxide and aluminum oxide.

An ink jet recording medium is disclosed. The recording medium comprises a support and a porous ink absorbing layer comprising inorganic particles and hydrophilic binder which is hardened employing inorganic hardener and organic hardener. The ink jet recording medium exhibits high ink absorbability and desired water resistance without degrading layer brittleness through sufficiently hardening the layer employing an appropriate amount of hardeners.

Ink jet recording medium

An ink jet recording sheet comprising a support having thereon a porous ink absorptive layer comprising, inorganic particles, polyvinyl alcohol and a zirconium compound or an aluminum compound, wherein the ink absorptive layer exhibits a concentration gradient of said zirconium compound or the aluminum compound, wherein the concentration increases from the surface of the support towards the surface of the ink absorptive layer.
