Title:
METHOD FOR MANUFACTURING RED RESIN COMPOSITION FOR COLOR FILTER AND METHOD FOR MANUFACTURING COLOR FILTER
Document Type and Number:
Japanese Patent JP2013064870
Kind Code:
A
Abstract:

To provide a red resin composition for a color filter having superior pigment dispersibility and dispersion stability, capable of manufacturing a colored layer having high contrast and small phase difference by suppressing deposition of pigment aggregation of the surface of the colored layer during a high-temperature heating step in a manufacturing step of the color filter.

Disclosed is a method for manufacturing a red resin composition for a color filter, which contains a crystal deposition inhibitor precursor, a diketopyrrolopyrrole pigment, a pigment dispersant, a curable binder component, and a solvent. This method includes the steps of: preparing a pigment dispersion liquid which disperse the diketopyrrolopyrrole pigment in a solvent in the presence of the pigment dispersant; and mixing at least the pigment dispersant, the crystal deposition inhibitor precursor, and a curable binder component with each other.
