Abstract
A heat-sensitive recording material includes a heat-sensitive recording layer containing a basic dye and a developer and provided on a supporting body, in which the developer is at least one type of an N-substituted amino acid derivative represented by the following General Formula: (R—X)m—Y—(Z)m . . . (1) (In Formula (1), R represents an alkyl group or an aryl group which may have a substituent. X is a group bonded to the N-terminus of Y, and represents —OCO—, —SO2NHCO—, —NHCO—, —NHCS—, or —SO2—. Y represents an amino acid residue or a peptide residue. Z represents a group bonded to the C-terminus of Y and represents an OH group or an OR″ group. When Y is an amino acid residue other than a cystine residue or when Y is a peptide residue not having a cystine residue, m=1, and when Y is a peptide residue having n cystine residues, m=n+1 and n is 1 or 2.)
