DETAILED DESCRIPTION What we claim is: 1.
An information recording medium, comprising an information recording layer of acrylic resin or methacrylic resin being laminated on an electrode layer, a liquid crystal phase that is a nematic phase or a cholesteric phase at operating environmental temperature being dispersed and fixed on said information recording layer, whereby weight average molecular weight of said acrylic resin or methacrylic resin is 25,000 to 100,000.
2.
An information recording medium, comprising an information recording layer of acrylic resin or methacrylic resin being laminated on an electrode layer, a liquid crystal phase that is a nematic phase or a cholesteric phase at operating environmental temperature being dispersed and fixed on said information recording layer, whereby weight average molecular weight of said acrylic resin or methacrylic resin is 25,000 to 100,000 and has an acid number of 2 or more.
3.
An information recording medium, comprising an information recording layer of acrylic resin or methacrylic resin and an electric charge retaining layer that are sequentially laminated on an electrode layer, a liquid crystal phase that is a nematic phase or a cholesteric phase at operating environmental temperature being dispersed and fixed on said information recording layer, whereby weigh average molecular weight of said acrylic resin or methacrylic resin is 25,000 to 100,000.
4.
An information recording medium according to one of claims 1 to 3, wherein said information recording layer is heated, before recording of information, at a temperature higher than room temperature and lower than the temperature at which liquid crystal transits to isotropic phase.
5.
An information recording medium according to one of claims 1 to 3, wherein said resin has glass transition temperature higher than operating environmental temperature.
6.
An information recording medium according to one of claims 1 to 3, wherein said information recording layer is laminated on the electrode layer via a charge blocking layer
