preparation example Construction

[0365]

[0366] 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 prepared 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.

[0367] Moreover, when preparing the photosensitive coloring composition containing a pigment, the process of dispersing a pigment is also preferable at the time of preparing a photosensitive coloring composition. In the step of dispersing the pigment, compression, extrusion, impact, shearing, cavitation and the like are mentioned as the mechanical force used in the dispersion of the pigment. Specific examples of these steps include bea...

Abstract

Provided is a photosensitive coloring composition which is capable of forming a cured film that exhibits excellent decoloration resistance with respect to a developer liquid. Also provided are: a cured film; a method for forming a pattern; a color filter; a solid-state imaging element; and an image display device. This photosensitive coloring composition contains: a photopolymerization initiator athat has an absorption coefficient of light having a wavelength of 365 nm of more than 1.0 plus 102 mL / gcm in methanol; a photopolymerization initiator b that has an absorption coefficient of light having a wavelength of 365 nm of 1.0 plus 102 mL / gcm or less and an absorption coefficient of light having a wavelength of 254 nm of 1.0 plus 103 mL / gcm or more in methanol; an alkali-soluble resin; and a colorant that has a polymerizable group. The content of the photopolymerization initiator a is 1.5% by mass or more and the content of the photopolymerization initiator b is 1.5% by mass or more in the total solid content of the photosensitive coloring composition.

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] The color filter is produced by applying a colored photosensitive composition for forming pixels of various colors on a support, performing prebaking at about 100°C, and then exposing and developing to form a pattern, followed by pos...
