Images are formed by directing radiation, such as red or infra-red laser light, at a radiation sensitive plate and modulating the radiation. The radiation-sensitive plate includes a coating comprising coreshell particles having a water insoluble heat softenable core component and a shell component which is soluble or swellable in aqueous alkaline medium. The radiation causes selected particles to coalesce, at least partially, to form an image and the non-coalesced particles are then selectively removed by means of an aqueous alkaline developer. |
