摘要： Relief plates and printing plates are produced by a positive-working process, using a photopolymerizable layer which contains one or more photopolymerizable, olefinically unsaturated compounds, one or more photoinitiators which can be activated by UV light, and a combination of a phenothiazinium, phenoxazinium, phenazinium or acridinium dye with a mild reducing agent which, on exposure to visible light, is capable of reducing the dye in the excited electronic state. The photopolymerizable layer is exposed imagewise to light having a wavelength longer than 450 nm, and simultaneously or subsequently exposed uniformly to light having a wavelength of from 300 to 420 nm, after which the unpolymerized areas of the layer are removed.

摘要： For the production of printing plates, in particular lithographic printing plates by exposing a photopolymerizable recording material imagewise to actinic light and then effecting development with an aqueous alkaline developer, it is proposed to use photopolymerizable recording materials possessing a photopolymerizable copying layer (L) applied on a dimensionally stable base, where, in addition to containing ethylenically unsaturated photopolymerizable low molecular weight compounds, one or more photoinitiators, dyes and/or pigments, and, if required, further additives and/or assistants, the said copying layer (L) also contains, as a binder, one or more oligomeric and/or relatively high molecular weight copolymers which are soluble or dispersible in aqueous alkaline media and are based on cyclic dienes, in particular unsubstituted or substituted cyclopentadiene or unsubstituted or substituted di- or tricyclopentadiene. Preferred copolymers based on these cyclic dienes contain, as further copolymerized building blocks, carboxylic anhydride-containing comonomers, in particular maleic anhydride, and/or comonomers containing free carboxyl groups, in particular maleic acid half esters.
