ABSTRACT:
A light-sensitive element which comprises a substrate having provided thereon a light-sensitive layer which comprises microcapsules containing at least an ethylenically unsaturated compound and a photopolymerization initiator as active substances, wherein the active substances diffused from the microcapsules are present on and around the surface of the microcapsules.
The light-sensitive element, when imagewise exposed to light, forms a continuous strong film in exposed areas, and unexposed areas can be easily washed off with water to give a printing plate which produces prints having no background contamination.
