The present invention concerns photopolymerisable systems comprising reactive oligomers and/or monomers having ethylenically unsaturated groups and at least one phenylglyoxalic ester that, by photochemical decomposition, generates fragments having low migratability and low odor.

Phenylglyoxalic esters generated by photolysis of low migratable fragments

This invention concerns photopolymerizable systems containing ethylenically unsaturated reactive oligomers and/or monomers comprising at least one photoinitiator and at least one coinitiator having low-extractability and low-volatility; the photopolymerizable systems of the invention are particularly suited for the preparation of food-packaging coatings.

Photopolymerisable systems containing low-extractable and low-volatile coinitiators

The present invention relates to clear photopolymerisable systems for the preparation of high thickness coatings, to a procedure for their application and to the solid surfaces coated with them.

The present invention relates to sulfonium salts, to methods for their preparation and to radiation curable compositions containing them as photoinitiators.

Sulfoniun salts, methods for their preparation and use thereof as photoinitiators for radiation curable systems

A composition for positive heat sensitive computer-to-plate (CTP) lithographic printing plates comprising a phenolic resin and an IR absorber characterized by the fact that the composition contains from 1 to 30% w/w of an organic oxygenated phosphorous compound chosen from the group of general formula (I): wherein R, R, and Rare independently a C&#x2013;Calkyl group or an aryl group.

Compositions for positive heat sensitive lithographic printing plates

The present invention refers to solid mixtures of alpha hydroxycarbonyl derivatives of alpha-methylstyrene oligomers containing at least 90% of the dimer isomers, the dimer isomer ratio being between 2.5 and 7, to their preparation and to their use as photoinitiators in photopolymerisation.

Solid mixtures of alpha-hydroxycarbonyl derivatives of alpha-methylstyrene oligomers and their use

Disclosed are chlorine containing polymer compositions containing stabilizers which impart good thermal stability. PVC compositions and, in particular, flexible PVC compositions containing stabilizers which are oligomeric and/or polymeric aminouracyls exhibit high thermal stability as evidenced by improved resistance to yellowing and blistering upon extended exposure to high temperatures.
