FLUORINE-CONTAINING POLYMER, NEGATIVE PHOTOSENSITIVE COMPOSITION AND PARTITION WALL

摘要

Disclosed is a fluorine-containing polymer which enables to reduce the amount of residual ink on a partition wall and to form an ink layer having high uniformity in film thickness, even when light exposure amount is low. Also disclosed is a negative photosensitive composition. Specifically disclosed is a fluorine-containing polymer which is a copolymer of two or more kinds of monomers having an ethylene double bond. This fluorine-containing polymer has a side chain which contains an alkyl group having 20 or less carbon atoms wherein at least one hydrogen atom is substituted by a fluorine atom (provided that the alkyl group may have an ether oxygen atom between carbon atoms), and another side chain having two or more ethylene double bonds. Also disclosed is a negative photosensitive composition containing such a fluorine-containing polymer.
