ABSTRACT:
A photosetting microcapsule containing a photosetting resin and a photopolymerization initiator can be controlled in rupture thereof. By utilizing such characteristics of said microcapsule and by using in combination said photosetting microcapsules containing a reactant such as an electron donative compound and the microcapsules containing a co-reactant such as an electron receptive compound capable of forming a colored material by reacting with said reactant or finely powdered co-reactant per se, there is provided a photo- and pressure-sensitive recording sheet which is capable of copying even a positive type original to provide a copy or copies with excellent keeping quality without causing any coloration or discoloration in the portion other than the characters, etc., of the original.
