摘要： A heat developable light sensitive material which comprises a support having therein or in one or more layers thereon (a) an organic silver salt, (b) a light sensitive silver halide or a component capable of producing a light sensitive silver halide and (c) a reducing agent and additionally contains (d) at least one phthalazinone and (e) at least one compound selected from benzoxazinediones and quinazolinediones in a molar ratio of the amount of the component (e) to that of the component (d) smaller than about 1:1 (i.e. molar ratio (e)/(d) 1) in at least one of the layers containing components (a) to (c), in a specific layer additionally provided on the support other than the layers containing components (a) to (c), or in the support to result in the production of images of a pure black tone and in improvements in shelf-life under high humidity and the developing speed.
