Abstract
A photo and pressure sensitive recording medium comprising a sheet shaped supporting member, microcapsules enveloping therein at least image developing materials and photo-sensitive resins, and plastic grains having large diameter than that of the microcapsule and being softenable when exposed to external energy. The microcapsules and the plastic grains are mixedly distributed and coated on one surface of said supporting member. Since the plastic grains are not softened until they are subjected to the external energy such as heat, light and so on, the microcapsules smaller than the plastic grains can be prevented from unintentional rupturing by fingers of operators or so during the transportation or so of the recording medium even though the microcapsules are prepared to be ruptuable by small pressure such as the pressure applied by the fingers or so.
