    Abstract: In the present invention, there is disclosed a process for catalytically hydrogenating aromatic compounds in which at least one amino group is bonded to an aromatic nucleus, which process comprises bringing at least one of said aromatic compounds as the reactant in a liquid phase into contact with free hydrogen in the presence of a carrier supported metal catalyst consisting essentially of ruthenium and optionally at least one additional metal of subgroup I, VII or VIII of the Periodic Table or mixtures thereof, said metal catalyst being applied to a carrier having a mean pore diameter of at least 0.1 micron and a surface area of not more than 15 me2/gram in an amount of from 0.01 to 30 percent by weight, based on the total weight of both the carrier and the applied metal, wherein the carrier is selected from the group consisting of active carbon, silicon carbide, alumina, silica, titanium dioxide, zirconium dioxide, magnesium dioxide, zinc oxide and mixtures thereof. Claimed are also the above-described catalyst and its use for hydrogenation of the aromatic compounds.

    Abstract: Photopolymerizable mixtures comprising one or more photopolymerizable, olefinically unsaturated compounds and one or more photoinitiators or photosensitizers, with or without other conventional additives and/or assistants, contain, as an activator, a tertiary amine of the general formula (I) (I) wherein R1 and R2 are each an unsubstituted alkyl, cycloalkyl or phenyl radical, hydroxyl or alkoxy, or R1 and R2 are bonded together to form a cyclic alkylene radical, R3 has the same meanings as R1 or R2 and may furthermore be hydrogen, acyloxy or substituted benzoyloxy, and R4 and R5 are each an unsubstituted or substituted alkyl, cycloalkyl or phenyl radical, or R4 and R5 are bonded together to form a cyclic alkylene or alkyleneoxyalkylene radical.
