Abstract
A radiation-crosslinkable mixture which contains a carboxyl-containing precursor of a heterocyclic polymer, a copolymerizable ethylenically unsaturated ternary sulfonium salt, a photoinitiator and a polar aprotic organic solvent.
Claims6
A radiation-crosslinkable mixture which consists essentially of the following components:
- (I) at least one carboxyl-containing polymeric precursor of a heterocyclic polymer, which polymer is stable at high temperatures, and which precursor is soluble in polar organic solvent,
- (II) at least one copolymerizable ethylenically unsaturated ternary sulfonium salt, which salt is a reaction product of thiodiglycol with glycidyl(meth)acrylate and an organic mono-, di- or polycarboxylic acid,
- (III) at least one photoinitiator or photoinitiator system which is different form component (II), and
- (IV) at least one polar aprotic organic solvent.
