ABSTRACT:
A variable electroconductivity material characterized by being obtained by formulating (a) an electroconductivity variation imparting agent comprising a substance which is caused by light or heat energy to undergo structural change, reversibly or irreversibly, between nonionic and ionic structures and (b) a charge transport substance the electroconductivity of which is varied by said structural change of said electroconductivity variation imparting agent, and an information recording medium obtained by the use of this material has excellent memory stability, and also a light (heat) converting device having conversion characteristics can be obtained by the use of this material.
