ABSTRACT:
A photosensitive and pressure-sensitive recording sheet and a process for recording an image using such recording sheet, said recording sheet comprising microcapsules, which enclose a first component, held on one side surface of a sheet and a second component, which causes color change of the surface of sheet when it reacts with the first component that is held on said one side surface of the sheet, held on the opposing side surface of the sheet and, moreover, one other component, which causes a change in the mechanical breaking strength of the microcapsule in response to exposure to light, enclosed in the microcapsules; and said process comprising exposing said one side surface of the sheet holding the microcapsules to a light, putting the so exposed surface of the sheet together with the surface, which holds the second component, of another recording sheet of the same construction and pressing the so laminated two sheets with each other.
