Abstract
1,109,554. Heat- and light-sensitive materials. NATIONAL CASH REGISTER CO. Nov. 4, 1966 [Jan. 13, 1966], No.49555/66. Heading G2C. A heat- and light-sensitive material comprises a support coated with a layer containing a wax melting above 40C. and in which is dispersed fine particles of 6'-nitro-1, 3, 3-trimethylbenzoindolino-spiropyran. The wax/spiropyran may be dispersed in a polymer before coating. The material is first heated to above the melting point of the wax and to sensitize the layer exposed to ultraviolet to give a magenta colour and then heated again to give a fixed blue colour, one of the three steps being imagewise. The magenta colour may be erased by exposure to green light or light of a longer wavelength and the blue colour may be erased by prolonged heating. An image can thus be produced by using various combinations of heat, ultraviolet and green light. A second image may be added to the first image by repeating the heating, ultraviolet exposure and heat-fixing steps. The waxes specified are ethylene glycol monostearate; paraffin, microcrystalline carnauba or bees-wax; spermaceti or fatty acid esters.
