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.

摘要： An arrangement is provided for fixing components of an optical system such as lenses, mounting rings, and the like. The components which are guided radially in the tube are held in the axial direction under pretensioning in an elastic manner. The arrangement is designed for fixing components in the axial direction in which the pretensioning force can be varied in definable steps. This is done by providing that a detachable fastening ring and also the tube have catch elements at concentric circumferential surfaces, which catch elements are constructed as complementing locking elements. Under axially directed force, the catch elements of the fastening ring can be engaged in the catch elements at the tube and the catch elements can be disengaged in the opposite force direction. The pretensioning force which is exerted by the fastening ring on the components to be held depends upon the extent to which the catch elements of the fastening ring and of the tube overlap.
