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.
Claims11
A heat-sensitive recording apparatus for performing heat-sensitive recording of information on a heat-sensitive recording sheet having on its surface a heat-sensitive layer containing a diazo compound and a coupling agent, which apparatus comprises:
- a thermal head comprising a plurality of heating elements for selectively heating the heat-sensitive layer corresponding to given information to be recorded;
- a photofixing system for photofixing the information recorded by the heating through the thermal head, which comprises a light emitting part for uniformly irradiating light over all the surface of the heat-sensitive recording sheet;
- a transporting means for passing the heat-sensitive recording sheet through a heating means including the thermal head and through a light-irradiating means including the photofixing system;
- and
- a preactivating system for optically activating said heat-sensitive layer before performing a heat recording.
