Abstract: Provided herein is a recording sheet composed of a support base and a recording layer formed thereon. The recording layer is formed by curing, with radiation, a material composed mainly of a hydrophilic resin prepolymer curable with radiation, said prepolymer having a polyether skeleton and ethylenic unsaturated groups curable with radiation at both terminals thereof.The recording sheet permits printing and drawing on an ink jet printer or pen plotter which uses water-based ink. The recording layer permits the writing and coloring in a water-based ink with a pen, marker, or fountain pen and yet has good water resistance. The recording sheet is particularly useful as a transparency for overhead projectors.

Abstract: A heat-sensitive recording material comprising a support, a heat-sensitive recording layer containing a color former and a color developer forming color by the contact with the color former formed on the support, an interlayer containing a water-soluble resin or a water-dispersible resin as the main component formed on the heat-sensitive recording layer, and an overcoat layer formed by forming a layer containing (1) a macromonomer having a polymerizable functional group at one terminal of the molecular chain, the main component of the segment being organopolysiloxane and (2) a resin capable of being cured by electron beams on the interlayer and curing the layer by the irradiation of electron beams.

Abstract: A heat-sensitive recording material is disclosed, comprising a support; a heat-sensitive recording layer formed on the support, which contains a color former and a color developer which forms a color upon contact with said color former; an interlayer with a Bekk smoothness of from 50 to 1,500 seconds formed on said heat-sensitive recording layer, which contains a water-soluble resin; and an overcoat layer formed on the interlayer, which contains a resin that is curable upon exposure to electron beams. The heat-sensitive recording material exhibits not only superior recording characteristics but also good preservability of recorded images, with widely varying surface characteristics ranging from a high gloss to a matted appearance.
