Abstract
Merocyanine dyes comprising 2-(heterocyclylcarbonylmethylene)thiazolines and selenazolines and 2-[di(heterocyclylcarbonyl)methylene]thiazolines and selenazolines are efficient sensitizers for light-sensitive unsaturated materials such as unsaturated vesiculators which release a gas upon exposure to radiation, photocrosslinkable unsaturated polymers, and azides such as photocrosslinkable polymeric azides used in photomechanical resists and lithographic plates.
