Pigment multimer, coloring composition, cured film, color filter, method for manufacturing color filter, solid-state imaging element, and image display device

摘要

Provided is a pigment multimer whereby a pattern can be appropriately formed during formation of a pattern. Further, provided are a coloring composition using the pigment multimer; and a cured film, a color filter, a method for manufacturing a color filter, a solid-state imaging element, and an image display device, each of which uses the coloring composition. The pigment multimer (A) has a non-nucleophilic counter anion.

主权项

1. A colorant multimer (A) having a non-nucleophilic counter anion,
wherein the non-nucleophilic counter anion is an imide anion represented by the following formula (AN-1):
X1—Y1—N−—Y2—X2  (AN-1) wherein X1 and X2 each independently represents a halogen atom, an alkyl group, or an aryl group; X1 and X2 may be bonded to each other to form a ring; at least one of X1 and X2 is a fluorine atom-containing alkyl group having 1 to 10 carbon atoms; and Y1 and Y2 each independently represents —SO2— or —CO—, and further wherein the colorant multimer (A) having a non-nucleophilic counter anion has a partial structure derived from a colorant selected from the group consisting of a dipyrromethene colorant and a xanthene colorant, and wherein the colorant multimer achieves a combination of high heat resistance and reduced color migration.
