<p>Disclosed is an optical recording medium which is characterized by having an optical recording layer, which is made of an optical recording material containing at least one heterocyclic compound represented by the general formula (I) below, on a base. (I) (In the formula, Z<SUP>1</SUP> represents an oxygen atom, a sulfur atom, -CR<SUP>5</SUP>R<SUP>6</SUP>- (wherein R<SUP>5</SUP> and R<SUP>6</SUP> respectively represent an alkyl group, an arylalkyl group or the like, and R<SUP>5</SUP> and R<SUP>6</SUP> may combine together to form a ring) or the like; R<SUP>1</SUP> and R<SUP>2</SUP> respectively represent a hydrogen atom or the like; R<SUP>3</SUP> and R<SUP>4</SUP> respectively represent an alkyl group having 1-8 carbon atoms, or they may combine together to form a group constituting a heterocyclic ring which does not contain a multiple bond; Y<SUP>1</SUP> represents a hydrogen atom, an alkyl group having 1-8 carbon atoms, a metallocene substituent or the like; An<SUP>q-</SUP> represents a q-valent anion, and q represents a number of 1 or 2; p represents a coefficient required for neutralizing the electrical charge; and n represents a number of 1-4.)</p> |
