    Abstract: Photocurable filling compounds for closing the gaps which result between the end or edge regions of gravure printing plates when the latter are clamped on forme cylinders consist of a homogeneous, solvent-free, photopolymerizable mixture which is free-flowing at room temperature and contains from 10 to 90% by weight of one or more hydrophilic, polar, photopolymerizable, ethylenically unsaturated low molecular weight compounds, from 5 to 65% by weight of one or more polymeric binders which are resistant to toluene-containing, gasoline-containing, ketone-containing and/or ester-containing solvents and are compatible with the photopolymerizable low molecular weight compounds, from 0.01 to 10% by weight of one or more photoinitiators and from 0 to 70% by weight of further additives and/or assistants.

    Abstract: Photopolymerizable recording substance which consists of a photoinitiator-containing mixture of at least one low molecular weight compound having at least one photopolymerizable olefinic unsaturated double bond and at least one organic polymeric binding agent, with use being made, as photoinitiator, of acylphosphine oxide compounds of the formula where R1 is an alkyl or cycloalkyl group, an aryl group which is optionally substituted by halogen, alkyl or alkoxy, or an S- or N-containing heterocyclic group, R2 is as R1, with it being possible for R1 and R2 to be identical or different, or is an alkoxy, aryloxy or arylalkoxy group, or R1 and R2 form a ring, R3 is a tertiary alkyl or cycloalkyl group, or a cycloalkyl, aryl or heterocylic group which has the substituents A and B at least in both the o positions in relation to the carbonyl group, which substituents A and B can be identical or different and denote alkyl, alkoxy, alkoxyalkyl, alkylthio, cycloalkyl, aryl or halogen. The recording substance imparts an improved relief structure to the finished print.
