Multifunction urethane monomer, method of manufacturing the monomer and photosensitive resin composition including the monomer

摘要

Disclosed is a multifunctional urethane monomer prepared by reacting (a) an epoxy compound having two or more epoxy groups, (b) a diol compound having an acidic group and (c) a compound having an ethylenically unsaturated group and an isocyanate group with one another. The photosensitive resin composition comprising the multifunctional urethane monomer has low viscosity, superior sensitivity, excellent chemical resistance and heat-resistance and high development margin.
