The present invention provides a recording medium for ink jet printers in which superior image recording quality and color stability are exhibited. In a recording medium for ink jet printers in which an ink receiving layer contained at least pigment and binder resin is provided on a supporting material, partially saponified PVA having a degree of saponification of 85.0 to 73.0 mol % and a degree of polymerization of 300 to 1500, is contained in the ink receiving layer as a color stability improving component.

Recording medium for ink jet printers

A recording sheet for an ink jet printer can improve both recording properties such as vividness of images, printing density, etc., and shelf life such as light resistance of images, ozone resistance, etc. The recording sheet for an ink jet printer comprises a base material and an ink receiving layer provided on at least one surface of the base material, in which the recording sheet contains oligosaccharide and divalent metallic salt.

Recording sheet for ink jet printer

A recording medium for ink jet printers having superior effects in preventing recorded image deterioration such as lowering of image clarity, decrease in density, change in color tone, etc., under high temperature and high humidity, is provided. An ink receiving layer is formed on a base material by coating acrylic copolymer containing at least (meth)acrylate having a solubility parameter (&dgr;) of 15.0 to 23.0 MPa as a copolymerizing component, and thereby a recording medium for ink jet printers is produced.

Ink-jet recording medium

A superior recording sheet for an ink jet printer which sufficiently satisfies various property requirements such as light resistance of images, ozone resistance, etc., is provided. The recording sheet for an ink jet printer comprises at least an ink receiving layer and a glossiness adjusting layer on a base material, the ink receiving layer includes an organic acid metallic salt and a cationic dye fixing agent, and the glossiness adjusting layer comprises a fine particle pigment and binder resin.

The invention provides an ink-jet recording sheet having an excellent preventive effect on overall. degradation by light such as degradation of image clarity, and decrease in density or change of tone of images, and a resin composition for ink-jet recording media used in the formation thereof. The recording sheet of the invention comprises a substrate and as an ink-receiving layer provided on the substrate, a layer containing an acrylic resin comprising, as copolymerizable monomers, (a) a dialkylaminoalkyl methacrylate, (b) acrylamide and (c) at least one monomer selected from among an. alkoxypolyethylene glycol methacrylate, a 2-hydroxyalkyl methacrylate and a 2-hydroxyalkyl acrylate.

Ink-jet recording sheet

A recording medium for ink jet printers having superior recording properties for ink jet printers and having superior surface strength in which recorded images are not easily peeled. Acrylic type copolymer in which at least three components of an A component: (metha)acrylate; a B component: hydroxyalkyl (metha)acrylate; and a C component: antioxidation monomer and/or ultraviolet ray absorptivity monomer are copolymerizing components is contained in a coating solution, an ink receiving layer is provided by coating this solution on a base material, whereby a recording medium for ink jet printers is formed.

Medium for ink-jet recording

The present invention provides a superior recording sheet for ink jet printers which can completely satisfy property requirements such as light resistance of the printing images. The recording sheet for an ink jet printer includes a water-soluble divalent or greater metallic salt, so that properties such as light resistance are improved very effectively.
