Abstract
An image recording medium comprising a light and heat change material capable of recording an image with laser beam is described, characterized in that therein are incorporated a heat generator having no absorption at a wavelength of 500 nm or more which undergoes exothermic decomposition to amplify heat generation when acted upon by heat and a compound which undergoes thermochemical reaction to show an absorption change at a wavelength of from 360 nm to 900 nm.
Claims5
An image recording medium capable of recording an image with laser beam comprising (i) a light and heat change material, (ii) a heat generator having no absorption at a wavelength of 500 nm or longer which undergoes exothernic decomposition to amplify heat generation when acted upon by heat, (iii) a compound which reacts with an acid to show an absorption change at a wavelength of from 360 nm to 900 nm, and (iv) a compound which generates an acid by the action of heat.
