Abstract
A dye and a recording material employing the dye are disclosed. The dye is represented by formulaB═N—AIn the formula, A represents a metal-free atomic group necessary to form a condensed ring having —NR1R2 as a substituent on the ring, except for one ring in which a carbon atom on the ring combines with the nitrogen atom in the formula. B represents a coupler component and combines with a nitrogen atom in the formula at coupling position of the coupler component. R1 and R2 each independently represents a hydrogen atom, an alkyl group which may have a substituent, an aryl group which may have a substituent, and a heterocycle which may have a substituent, and R1 and R2 may combine with each other to form a ring.
