ABSTRACT:
3-Substituted coumarins are efficient sensitizers for light-sensitive unsaturated materials such as unsaturated vesiculators which release a gas upon exposure to radiation, unsaturated monomers and photocrosslinkable unsaturated polymers, and azides such as photocrosslinkable polymeric azides used in photomechanical resists and lithographic plates. Water soluble derivatives can be used for aqueous coatable or aqueous processable systems.
