Description

The present invention relates to a colored curable resin composition containing a specific compound having a polymethine structure.

Polymethine compounds such as merocyanine are used in, for example, optical filters (Patent Document 1). In the column of Examples of this Patent Document 1, the following compound No. 2 and No. An optical filter is manufactured using the iodine salt of 3.

However, in Patent Document 1, the brightness of the color filter is not evaluated.
By the way, it is desirable that the colorant having a maximum absorption wavelength of 500 nm or more and 700 nm or less further increase its brightness. As an example of using such a colorant, Patent Document 2 discloses an example in which a specific xanthene dye and Pigment Red 254 are combined, and Patent Document 3 describes Pigment Red 242 and Pigment Red 177. A combination example is disclosed. It is desirable to further increase the brightness of such a combination colorant.

<Manufacturing method of color filter>
Examples of the method for producing a colored pattern from the colored curable resin composition of the present invention include a photolithography method, an inkjet method, a printing method and the like. Above all, the photolithography method is preferable. The photolithography method is a method in which the colored curable resin composition is applied to a substrate and dried to form a colored composition layer, and the colored composition layer is exposed and developed through a photomask. In the photolithography method, a colored coating film which is a cured product of the coloring composition layer can be formed by not using a photomask at the time of exposure and / or not developing. The colored pattern or colored coating film thus formed is the color filter of the present invention.
The film thickness of the color filter to be produced is not particularly limited and can be appropriately adjusted according to the purpose, application, etc., and is usually 0.1 to 30 μm, preferably 0.1 to 20 μm, more preferably 0.5 to It is 6 μm.

As the substrate, a glass plate, a resin plate, silicon, or a substrate on which an aluminum, silver, silver / copper / palladium alloy thin film, or the like is formed is used. Another color filter layer, resin layer, transistor, circuit and the like may be formed on these substrates.

The formation of each color pixel by the photolithography method can be performed by a known or conventional device or condition. For example, it can be produced as follows.
First, a colored curable resin composition is applied onto a substrate and dried by heating and drying (prebaking) and / or under reduced pressure to remove volatile components such as a solvent to obtain a smooth colored composition layer.
Examples of the coating method include a spin coating method, a slit coating method, a slit and spin coating method, and the like.

The coloring composition layer is then exposed via a photomask to form the desired coloring pattern.

An exposure device such as a mask aligner and a stepper should be used because it is possible to uniformly irradiate the entire exposed surface with parallel rays and accurately align the photomask with the substrate on which the coloring composition layer is formed. Is preferable.

A coloring pattern is formed on the substrate by developing the coloring composition layer after exposure by bringing it into contact with a developing solution. By development, the unexposed portion of the coloring composition layer is dissolved in a developing solution and removed. As the developing solution, for example, an aqueous solution of an alkaline compound such as potassium hydroxide, sodium hydrogen carbonate, sodium carbonate, or tetramethylammonium hydroxide is preferable.
The developing method may be any of a paddle method, a dipping method, a spray method and the like. Further, the substrate may be tilted at an arbitrary angle during development.
After development, it is preferable to wash with water.
Further, it is preferable to post-bake the obtained coloring pattern.

By using the color curable resin composition of the present invention, a color filter having particularly high brightness can be produced. The color filter is useful as a color filter used in display devices (for example, liquid crystal display devices, organic EL devices, electronic paper, etc.) and solid-state image sensors.
