ABSTRACT:
A thermodevelopable photo-recording method suitable for making bar-code labels, ID cards and the like, comprising using a thermodevelopable photo-recording material provided with thermodevelopable photo-recording layer containing at least a diazo compound and a coupler, and an electricity modulation type light shutter constructed by minute matrixes which come to be able or inable to transmit light when electric current is passed therethrough, and optionally an optical system for minizing or enlarging the final image, exposing said photo-recording material to light through a temporary image formed in said light shutter by turning on or off the electricity to pass through each of the minute matrixes, then heating said photo-recording material to get a record of the image therein.
