Abstract
A heat-sensitive recording sheet is proposed which has a heat-sensitive recording layer laminated on the surface of a support body and containing a diazosulfonate; a coupling agent; and a thermoplastic resin having a glass transition point of 70.degree.-150.degree. C. or a photocuring resin. A method for fixing a heat-sensitive recording is disclosed in which light of 400-550 nm in wavelength is irradiated on said heat-sensitive recording layer for optically activating it, a thermal head is used for heat-sensitive recording, and light of 300-450 nm in wavelength is irradiated on the recording layer for photofixing the recorded information. A device for effecting such heat-sensitive recording is also proposed.
