ABSTRACT:
A heat developable light-sensitive material containing a compound represented by the following general formula (I): ##STR1## wherein R.sub.1 and R.sub.2, which may be the same or different, each represents a hydrogen atom, an alkyl group, a substituted alkyl group, a cycloalkyl group, an aralkyl group, a substituted aralkyl group, an aryl group, a substituted aryl group or a heterocyclic group, or R.sub.1 and R.sub.2 are bonded to each other to form a 5-membered or 6-membered carbocyclic ring or a heterocyclic ring which may be a saturated ring, an unsaturated ring or an aromatic ring, may be condensed and may further have one or more substituents; M represents an alkali metal ion, an alkaline earth metal ion, a transition metal ion, a protonated organic base or a quaternary ammonium ion; and n represents a reciprocal of the positive charge number of M. The heat developable light-sensitive material containing a base precursor represented by the general formula (I) has excellent stability during preservation and provides a color image having a high color density and low fog in a short time.
