摘要： This invention relates to a process for preparing printing plates which are used in offset printing. The process produces a plate which comprises a substrate film in which a thin durable hydrophilic layer has been applied thereto. In the process, the substrate film is first microroughened by pressure blasting so that the surface roughness, R.sub.A, is in the range 0.3 to 1.5 .mu.m. Subsequently, a durable, firmly adhering hydrophilic layer is applied to substrate by plasma-spraying an oxide powder with a particle size of 1 to 40 .mu.m onto the substrate. This process produces a plate whose surface is not greasy or grainy.

摘要： The invention describes a photopolymerizable recording material which comprises a photopolymerizable layer and a cover layer. The cover layer comprises a polymer which possesses low permeability to atmospheric oxygen and is soluble in water, and a water-soluble dye which absorbs light in the region from 300 to 700 nm and within this range has a non-absorbent region corresponding to the emission range of the copying light source.The material can be sensitized for various spectral regions, for example, for UV light, visible light or laser light and has a higher resolving power than a corresponding material which does not contain a dye in the cover layer, while its photosensitivity remains unchanged or is only slightly reduced.
