Abstract: A selectively permeable membrane for an enzyme electrode is prepared by forming a mixture of an emulsion of resin containing at least one prepolymer or monomer having ethylenic unsaturation, and a water-soluble polymer material, and subjecting the mixture to irradiation with ionizing or ultraviolet irradiation. The membrane is permeable to substances produced by an enzyme reaction while preventing the permeation of higher molecular weight materials. An immobilized enzyme membrane is formed on an outer surface of the permeable membrane, and the resultant membrane is mounted on an electrically conductive base to form an enzyme electrode. In another embodiment, the selectively permeable membrane is formed on the electrically conductive base, and then the immobilized enzyme membrane is formed. The selectively permeable membrane is situated between the immobilized enzyme membrane, which is in contact with a sample solution, and the electrically conductive base.

Abstract: An image-receiving sheet for thermal dye-transfer recording using a sublimable dye is disclosed, comprising a support having thereon an image-receiving layer for receiving a transferred image from a coloring material-transferring sheet, wherein said image-receiving layer is a layer formed by coating a substantially solvent-free coating composition comprising (A) a macromonomer dyeable with a sublimable dye and containing a radical polymerizable functional group at one terminal of the molecular chain thereof, said macromonomer being solid at room temperature, dissolved in (B) a liquid radiation-curable monomer and/or oligomer on a support and irradiating the coat with radiation. The image-receiving sheet has high surface gloss, undegoes no blocking with the coloring material-transferring sheet, and provides a recorded image having high density and excellent storage stability.

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 process for the production of heat-sensitive recording materials is described, comprising the steps of (1) applying to a support a coating composition comprising a color former, a color developer, and at least one of a water-soluble binder and a water-dispersible binder, to form a layer, and (2) irradiating the layer with electron beams. Images recorded on the heat-sensitive recording material exhibit superior stability. The color density of the recorded images remains stable even when the recording material is moistened with water or placed in a high humidity atmosphere. Further, even moistened recorded images do not disappear when rubbed with a finger.
