Abstract: A recording material comprising a support coated with a photosensitive layer comprising a photosensitive diazo compound enclosed in microcapsules and a coupling component. The microcapsules are produced by forming an organic solution containing the diazo compound and a wall monomer, and emulsifying the organic solution in an aqueous solution containing an anionic surface-active agent and polyvinylpyrrolidone to produce oil droplets containing the wall monomer. The wall monomer is polymerized to form a wall around the oil droplets. When heat is applied to the photosensitive layer under alkaline conditions, the coupling component reacts with the diazo compound to form a color.
