Abstract:
Provided are an information recording medium which is excellent for long-term storage and with which high-density recording is possible, a method for producing the information recording medium, and an information recording material. A recording mark is formed by condensing pulse laser light onto a recording layer obtained by polymerization of a curing agent and a thermosetting epoxy resin having a highly two-dimensional skeleton. It is possible to reduce the distance between recording marks (voids) by bringing the molecular weight between crosslinking points in the cured product of the recording layer to 2,000 or less, preferably 500 or less.
