ABSTRACT:
An optical recording medium of the present invention has a recording layer containing an organic coloring matter expressed by the following formula (I) or (II): ##STR1## wherein R.sub.0 through R.sub.5 each indicate a hydrogen atom or an monovalent organic residue, at least one of R.sub.0 through R.sub.3 being a fluorine-containing monovalent organic residue; m indicates 0, 1 or 2; and X.sup..crclbar. indicates an anion residue. ##STR2## wherein X.sup..crclbar. indicates an anion residue; m indicates 0, 1 or 2; and R.sub.0' and R.sub.3' are atoms forming combinations of R.sub.0' and R.sub.1', and R.sub.2', and R.sub.3' at least one of which forms, with a nitrogen atom, a fluorine-containing substituted or unsubstituted pyrrolidine ring, a fluorine-containing substituted or unsubstituted piperidine ring, a fluorine-containing substituted or unsubstituted morpholine ring, a fluorine-containing substituted or unsubstituted tetrahydropyridine ring, a fluorine-containing substituted or unsubstituted cyclohexylamine ring expressed by the formula ##STR3## and the other substituents each being a hydrogen atom or a monovalent organic residue; and R.sub.4, and R.sub.5, each indicate a hydrogen atom or a monovalent organic residue.
