Heat-sensitive recording material

A heat-sensitive recording material comprising a support having succesively disposed thereon at least a heat-sensitive recording layer, a light transmittance adjusting layer and a protective layer, wherein the light transmittance adjusting layer contains two or more kinds of UV absorbent precursors represented by the following general formula (1), and a UV absorbent converted from at least one of the UV absorbent precursors has a maximum absorption wavelength of 348 nm or more
