Abstract
An information recording sheet of the present invention includes a substrate sheet, a variable information recording layer formed on the substrate sheet and a fixed information recording layer formed on a part of the variable information recording layer and made of a subliming dye receptor layer.
Claims3
An information recording sheet comprising:
- a substrate sheet;
- a variable information recording layer formed on said substrate sheet,
- a fixed information recording layer, wherein said variable information recording layer comprises a reversible heat sensitive layer, wherein said fixed information recording layer is made of a subliming dye receptor layer and includes a mold release agent, and said fixed information recording layer is formed on a part of said variable information recording layer;
- and further wherein thermal processing is performed on a surface of said fixed information layer, and information is stored on said fixed information recording layer and said variable information recording layer, respectively, wherein said fixed information recording layer is buried into said variable information recording layer.
