Provided are a photosensitive composition and a printing plate precursor capable of suppressing adhesion of an uncured portion to a photosensitive layer or the like in a water development step. A photosensitive composition used for a printing plate precursor that is developed by water development, comprising a water-dispersed latex, a millable rubber, a photopolymerization initiator, a photopolymerizable compound, and a surfactant. Inside, the water-dispersed latex is present as a spherical body 18, and the spherical body 18 is covered with a layer 20 containing a surfactant. The printing plate precursor 10 includes a photosensitive layer 14 made of a photosensitive composition. [Selection] Figure 1 |
