Abstract: A lithographic printing plate precursor comprises an imageable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye that is defined by Structure (I) shown in the disclosure, which dyes comprise one or more ethylenically unsaturated polymerizable groups in an organic group that is attached to the methine chain. These infrared radiation absorbing dyes exhibit a reduced tendency to crystallize in the imageable layers in the presence of tetraaryl borate counter anions and therefore provide improved shelf life.

Abstract: Imaged lithographic printing plates are processed using a developer that is replenished with only water, but replenishment is at a rate to allow developer volume to slowly decrease from a developer reservoir. This allows for a longer processing cycle especially when the developer is supplied from a container having a defined amount and applied using spray devices where water evaporation from the developer can be significant. Water lost by evaporation is replenished while water carried out by lithographic printing plates is not replenished.

Abstract: In a method for manufacturing an integrated, optical waveguide component having fiber couplings, a substrate component and a cover component are used, the cover component being obtained by forming a positive-negative replica of the substrate component. To separate the optical waveguide pattern region from the regions of the fiber couplings, grooves, as well as corresponding webs, are provided transversely to the fiber couplings. The method eliminates the need for carrying out the fiber adjustment and the waveguide formation in one process.
