A thermal imaging system is provided which includes a heat-sensitive element comprising at least one imaging layer having a selected depth dimension and having therein one or more spectrally absorbing organic materials responsive to the radiation employed for imagewise exposure. The percentage concentration of the organic material increases with depth in a predetermined manner so as to provide uniform heating depthwise within the imaging layer.
