ABSTRACT:
A photopolymerisable composition particularly useful as a solder resist composition able to withstand molten solder without loss of adhesion, pitmarks or shrinkage and for forming durable coatings on substrates generally is obtained by a combination of a photoinitiator, a polythiol acting as a chain modifier, and a polymer having hydroxy terminated chains capped by acrylate groups connected to the chains via the residue of a polyisocyanate.
