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.

Clear photopolymerizable systems for the preparation of high thickness coatings

The present invention is refereed to a white solid photoinitiator in the form of powder and consisting of 2-hydroxy-1-{4-[4-(2-hydroxy-2-methyl-propionyl)-phenoxy]-phenyl}-2-methyl-propan-1-one (COMPOUND1), and to the procedure for its preparation.

White solid photoinitiator in the form of powder and preparation thereof

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.
