Abstract
A heat-developable color light-sensitive material is described, which comprises a light-sensitive silver halide, a binder, a dye-donating compound and at least one compound represented by the following formula (I) on a support: ##STR1## wherein R.sub.1 represents an alkyl group having from 1 to 30 carbon atoms, an alkenyl group having from 2 to 30 carbon atoms, a cycloalkyl group having from 3 to 30 carbon atoms, or an aryl group having from 6 to 36 carbon atoms; R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each independently represents a hydrogen atom, an alkyl group having from 1 to 30 carbon atoms, or an alkenyl group having from 2 to 30 carbon atoms; m represents an integer of from 0 to 10; and n represents 0 or 1; with the proviso that, when m is an integer of from 1 to 10, n is 0; when n is 1, m is 0; when m is an integer of from 2 to 10, the plurality of R.sub.2 groups may be the same or different, and the plurality of R.sub.3 groups may be the same or different; R.sub.1 and R.sub.2, R.sub.2 and R.sub.3, or R.sub.4 and R.sub.5 each may be bonded to each other to form a ring; and the compound represented by formula (I) has from 10 to 50 total carbon atoms.
