PIGMENT DISPERSED COMPOSITION, COLORED PHOTOSENSITIVE COMPOSITION USING SAME AND NOVEL COMPOUND

摘要

PROBLEM TO BE SOLVED: To obtain the pigment dispersed composition superior in dispersion stability and fluidity and high in light transmittance and coloring power by dispersion an organic pigment and a copolymer of a polymerizable oligomer having a terminally ethylenically unsaturated double bond and a specified monomer. SOLUTION: The organic pigment and the monomer of a polymerizable oligomer having a terminally ethylenically unsaturated double bond and a monomer having an N-atom and an ethylenically unsaturated bond are dispersed into an organic solvent, and this monomer is represented by the formula R<11> is an H atom or a methyl group; R<12> is a 1-8 C alkylene group; X<1> is a -N(R<13> )(R<14> ) or pyrrolidino, pyrrolidyl, pyridyl, piperidino, or morpholino group; each of R<13> and R<14> is, independently, an H atom or a 1-6 C alkyl or phenyl group; and each of (m) and (n) is, independently, 1 or 0.
