    摘要： The invention relates to the use of a new class of sulphurated derivatives of aromatic-aliphatic or aliphatic ketones as a) polymerization or crosslinking photoinitiators for transparent or pigmented mixtures containing ethylenically unsaturated photopolymerizable compounds, in particular for obtaining polyacrylates, b) photochemically releasable latent acid catalysts, useful for crosslinking systems polycondensable by acid catalysis, of the type comprising etherified aminoplasts together with compounds containing hydroxyl, carboxyl, amido, amino and other functionalities.Said sulphurated derivatives enable manufactured articles to be obtained with exceptionally clear color while maintaining photochemical reactivity at high levels.

    摘要： As initiators for the photopolymerisation of ethylenically unsaturated compounds, the use of systems consisting of compounds of benzophenone type of formula I ##STR1## in which R, R' and R.sup.2 are preferably alkyls of 1-4 carbon atoms, R.sup.3 and R.sup.4 are preferably hydrogen and Ar is preferably phenyl, in combination with donors of hydrogen or substances which determine the formation of labile photochemical complexes, such as alcohols, ethers and tertiary amines with hydrogen in the alpha position, and the use for the same purpose of mixtures of 2,4,6-trialkylbenzophenones and benzophenone and particularly of a mixture of 2,4,6-trimethylbenzophenone and benzophenone in a molar ratio of 1.155, which has the advantage of being liquid at temperatures exceeding 10.degree. C. and of possessing photochemical activity superior to that of benzophenone.
