Abstract:
A method for forming an image is described which includes bringing a transparent heat-sensitive recording material including a transparent support made of a synthetic polymer having thereon a transparent heat-sensitive recording layer into contact with a light-absorbing material, at least at the time of effecting recording, and irradiating the light-absorbing material with a laser beam to heat the transparent heat-sensitive recording layer and to cause color formation therein. High speed, high density, and high quality recording can be performed with an increased light absorption efficiency.
