Zusammenfassung:	PURPOSE:To prevent the transfer of the leuco compound as dyestuff fore cursor to an adbesive layer by forming a photosensitive resin composition mainly from a microcapsule containing the leuco compound having the ethylenic unsaturated bond, photopolymerization starting agent, and tne leuco compound as dyestuff forecursor. CONSTITUTION:A photosensitive reisn composition mainly consists of a microcapsule containing the compound having the ethylenic unsaturated bond, photopolymerization starting agent, and the leuco compound as dyestuf precursor. The microcapsule containing the leuco compound develops color when light is irradiated. The substance for forming a capsule wall preferably polyvinyl alcohol. The polyvinyl alcohol preferably possesses the sapcnification degree of 60% or more, and more preferably 75% or more. The dimension of the capsule is preferably 0.01-25mum in diameter, and more preferably 0.1-20mum. Since the leuco compound does not tansfer to an adhesive layer for joining the photosensitive layer and a substrate, the color development of the adhesive layer is prevented.
