Document Type and Number:
Japanese Patent JP2023061273
Kind Code:
A
Abstract:
To provide a diketopyrrolopyrrole dye derivative for a color filter having high heat resistance and being effective in exhibiting high lightness, high contrast, viscosity stability and suppressing deposition of crystals of a diketopyrrolopyrrole-based pigment in a heating step, a production method of the dye derivative, a pigment composition for a color filter containing the dye derivative, a coloring composition, the color filter and a liquid crystal display device and a solid image pickup device including the same.SOLUTION: The problem is solved by a diketopyrrolopyrrole dye derivative (A1) for a color filter represented by formula (1), a pigment composition for the color filter containing the dye derivative (A1), and a coloring composition for the color filter. (In the formula, E represents a basic group. n is 1 or 2, m is 0 or 1, and n+m=2.)SELECTED DRAWING: None
