A tack sheet for ink jet recording, which comprises an ink jet recording sheet having at least one ink-receiving layer formed on one side of a support and an adhesive layer formed on the other side of the support, and a release sheet integrated thereto to cover the adhesive layer, wherein a cationic polymer is contained or impregnated in at least one of the support and the ink-receiving layer, and the ink jet recording sheet has an internal bond strength of from 120 to 320 g.multidot.cm/cm.sup.2 as measured in a wet state after being immersed in water at 20.degree. C. for 10 seconds, in accordance with TAPPI USEFUL METHODS NO. 403.

Tack sheet for ink jet recording

The invention provides an ink-jet recording medium for forming record images using an aqueous ink containing at least one water-soluble dye selected from direct dye, acidic dye, basic dye, reactive dye and dye for food, said medium containing at least one of acetylene glycol, ethylene oxide addition product of acetylene glycol and acetylene alcohol which have one triple bond in the molecule. This ink-jet recording medium provides images or letters of high density and besides is excellent in ink absorbency.

Ink-jet recording medium

There is disclosed a heat-sensitive recording material comprising a support and a heat-sensitive recording layer formed on said support; said heat-sensitive recording layer containing an aromatic isocyanate compound and an imino compound as color developing agent and a silane-modified acrylic resin constituting at least a part of binder.

Heat-sensitive recording material

An ink jet recording medium containing a poly(dialkanol allylamine) derivative or a poly(dialkanol modified alkylene glycol) derivative in a support or in an ink receiving layer formed on the substrate or coated on the ink receiving layer provides images or letters of high density and of superior water resistance and light resistance.

Ink jet recording medium

An ink jet recording sheet which comprises a transparent support and, provided thereon, at least one ink-receiving layer which is a light transmission layer containing an emulsion polymerized composition can form a color image of high resolution and high color density and the recorded sheet is suitable for overhead projector.
