DISPERSING AID, AQUEOUS DISPERSION OF ORGANIC PIGMENT NANOPARTICLE USING THE SAME, AGGLOMERATES, NONAQUEOUS DISPERSION, COLORED PHOTOSENSITIVE RESIN COMPOSITION OBTAINED BY THE SAME, COLOR FILTER USING THE SAME AND LIQUID CRYSTAL DISPLAY DEVICE

摘要

A dispersion aid is provided to increase fabrication efficiency while raising the contrast of a color filter, to realize excellent indication characteristic of a liquid crystal display, and to make efficient production of nonaqueous dispersion having stable dispersibility. A dispersion aid has a structure represented by the following chemical formula (1-1) or (1-2). In the chemical formula (1-1), A shows a heterocyclic group bonded with a linker by nitrogen atoms; X shows at least C2~20 divalent linker; R1 and R2 independently show hydrogen atom, alkyl group, aralkyl group or aryl group, or R1 and R2 are connected or can form a heterocyclic containing oxygen atom, nitrogen atom and/or sulfur atom; m shows a natural number of 1 or 2. In the chemical formula (1-2), A^11 shows a heterocyclic group connected to a carbonyl group by a nitrogen atom; and X^11 shows C2~10 divalent alkylene group which may have a substitution group, ether group or polyether group.
