[0312]

[0313] The photosensitive coloring composition of this invention can mix and prepare the said component. When preparing the photosensitive coloring composition, all the components can be dissolved and / or dispersed in the solvent at the same time to prepare the photosensitive coloring composition, and each component can also be properly used as two or more kinds of solutions or dispersions according to needs, And these are mixed at the time of use (at the time of coating), and the photosensitive coloring composition is prepared.

[0314]Moreover, when preparing the photosensitive coloring composition containing a pigment, it is also preferable that it is the process of dispersing a pigment, when preparing a photosensitive coloring composition. In the step of dispersing the pigment, compression, extrusion, impact, shearing, cavitation, etc. are mentioned as the mechanical force used in the dispersion of the pigment. Specific examples of these steps include bead mills...

Abstract

Provided are: a photosensitive coloring composition; a cured film; a method for forming a pattern; a color filter; a solid-sate imaging element; and an image display device. The photosensitive coloring composition includes: a color material; a photopolymerization initiator A1 having, in methanol, an absorption coefficient of 1.0*104 mL / g*cm or greater with respect to light of a 365 nm wavelength;a photopolymerization initiator A2 having, in methanol, an absorption coefficient of 1.0*102 mL / g*cm or less with respect to light of a 365 nm wavelength, and an absorption coefficient of 1.0*103 mL / g*cm or greater with respect to light of a 254 nm wavelength; and a polymerizable monomer. The content of the polymerizable monomer in the total solid content of the photosensitive coloring compositionis 15 mass% or greater.

Description

technical field [0001] The present invention relates to a photosensitive coloring composition. More specifically, it is related with the photosensitive coloring composition used for forming the colored pixel of a color filter, etc. In addition, it relates to a cured film using a photosensitive coloring composition, a method for forming a pattern, a color filter, a solid-state imaging device, and an image display device. Background technique [0002] In recent years, the demand for solid-state imaging devices such as charge-coupled device (CCD) image sensors has increased significantly due to the spread of digital cameras, camera-equipped mobile phones, and the like. Use color filters as key devices in displays and optical components. [0003] A color filter is manufactured using the photosensitive coloring composition containing a color material, a polymerizable monomer, and a photoinitiator. For example, Patent Document 1 describes that a color filter is produced using a...
