  • Sensitizers for photocrosslinkable polymers
    Patent number: 4119466
    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.
    Type: Grant
    Filed: August 31, 1977
    Date of Patent: October 10, 1978
    Assignee: Eastman Kodak Company
    Inventors: James Albert Van Allan, Michael Paul Cunningham, Donald Paul Specht, Samir Yacoub Farid
