PHOTOSENSITIVE COLORING COMPOSITION AND COLOR FILTER USING THE COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide photosensitive coloring composition with high sensitivity, an overhung shape hardly formed it excessive development take places, a wide development management range and good operability not necessarily to require the formation of an oxygen cutoff film and a color filter using the composition. SOLUTION: Acrylic resin for which monomer with unsaturated double joints to epoxy groups is added to monomer with unsaturated double to carboxylic acid groups and other monomer copolymer possible to copolymerize the monomer, pigment, dispersing agent, photopolymerizing monomer and photopolymerization initiator are contained. High sensitivity allows a less exposure time to be required and a manufacturing period to be shortened.
