摘要：
The information recording medium of the present invention comprises an information recording layer made of acrylic resin or metacrylic resin 11 being laminated on an electrode layer 13, a liquid crystal phase 12 being dispersed and fixed on said information recording layer, whereby said acrylic resin or metacrylic resin has weight average molecular weight of 10,000 to 100,000, electrostatic information can be permanently recorded and stored as visible information, and the visible information can be reproduced at any desired time. Further, the visible information can be easily erased by heating, and medium can be re-used.
