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.
