A heterogeneous photo-initiator in microparticle form, consisting of a finely divided substrate to which the same or different photo-initiators are covalently bonded. The photo-initiators are suitable for the radiation-induced polymerisation of photopolymerisable or photo-cross-linkage monomers to produce mouldings, protective coatings and relief images.
L'invention concerne un photoamorceur hétérogène se présentant sou la forme de microparticules, lequel est constitué d'une base en fines particules, à laquelle sont fixés par liaison covalente des photoamorceurs identiques ou différents. Les photoamorceurs peuvent être utilisés dans la polymérisation, induite par rayonnement, de monomères photopolymérisables ou photoréticulables pour la fabrication de corps moulés, de couches de protection et d'images en relief.
