Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a color filter used for a liquid crystal display device and a solid-state image pickup device.

[0002]

2. Description of the Related Art Conventionally, a color filter is manufactured by the following procedure. The colored layer is patterned on the transparent substrate.
A transparent protective film is formed on the coloring layer. A pattern of a transparent conductive film is formed. Here, the transparent protective film is important for flattening the patterned colored layer and protecting the colored layer.

The transparent protective film is required to have properties such as transparency, surface flatness, hardness, heat resistance, weather resistance and adhesion. Examples of the transparent protective film include acrylic resin disclosed in JP-A-3-251819, epoxy resin disclosed in JP-A-2-228630, polyimide resin disclosed in JP-A-61-254905, and JP-A-63-254905. A silicone resin disclosed in Japanese Patent Application No. 241076 is known. Silicone resins are excellent in transparency, surface flatness, heat resistance, weather resistance, and hardness, but have problems in adhesion and crack resistance. Polyimide resins are excellent in heat resistance, weather resistance, and adhesion, but are not necessarily sufficient in surface flatness and hardness.

JP-A-63-291924 discloses a resin obtained by modifying a silicone resin with an imide group. The imide-modified silicone resin has improved adhesion and crack resistance while maintaining the properties of the silicone resin.

However, since the imide-modified silicone resin is composed of a hydrolyzate of an alkoxysilane, a lower alcohol having a boiling point of 100 ° C. or less, which is generated in a large amount by hydrolysis, is present in the coating composition. Since the low-boiling alcohol evaporates rapidly during coating, convection occurs inside the applied coating composition, and the appearance of the applied coating becomes extremely poor. This uneven coating causes uneven cell gaps of the element and causes deterioration of display quality.

[0006]

In order to remove alcohol R ⁴ OH produced by the hydrolysis reaction, particularly lower alcohols, from the mixture of the hydrolyzate and the partial condensate obtained by the hydrolysis reaction, it is preferred to carry out distillation under normal pressure or reduced pressure.

The normal pressure distillation is preferably performed at a temperature of 60 ° C. or more and 130 ° C. or less, and the reduced pressure distillation is performed at a pressure of 10 Torr or more and 2
It is preferable to perform the treatment at a pressure of 100 Torr or less at a pressure of 00 Torr or less. The time for distillation is not particularly limited, and can be appropriately selected depending on the amount of alcohol distilled off.

The distillation is preferably carried out after the production of the hydrolyzate (B) and before the mixing with the compound (A), but after mixing the compound (A) and the hydrolyzate (B), It can also be carried out after mixing (A), the hydrolyzate (B) and the surfactant described below. If coating unevenness occurs due to rapid evaporation of low-boiling alcohol at the time of coating, it will cause the display quality of the color filter to deteriorate,
The amount of alcohol distilled off is preferably 50% or more, more preferably 70% or more, of the amount of alcohol produced by hydrolysis.

To improve the appearance of the coating, it is effective to distill off alcohols, especially lower alcohols. However, it is more effective to add a silicone-based surfactant. The performance is improved. The addition amount is 0.01% by weight or more and 5% by weight of the whole composition.
The following is preferred. The surfactant may be added at the time of adjusting the components (a) and (b) or after the adjustment. However, it is preferable that the surfactant is previously dispersed in a solvent to be added at the time of adjustment in order to uniformly mix the components. . Examples of the silicone-based surfactant include "Floren" WS (manufactured by Kyoeisha Yushi), "DISPARON"# 1610, # 1721, and # 1761 (manufactured by Kusumoto Kasei), "Aditol" XL121, 122 (manufactured by Hoechst), and Byk-300.

In the case of mixing before distillation, the weight ratio of the compound (A) and the hydrolyzate (B) can be selected in the range of 1: 0.4 to 1:13. If the amount of the component (a) is too large, coloring, a decrease in hardness, and a decrease in viscosity stability become problems. If the amount of the component (b) is too large, the adhesion and the cracks become problems.

The compound (A) and the distillation product (B ') are mixed, or the compound (A) and the hydrolyzate (B) are mixed and then subjected to normal pressure or reduced pressure distillation, or further to a surfactant. A curable composition is prepared by adding an agent,
At that time, the concentration can be adjusted by adding a solvent. As the solvent, a polar solvent having a boiling point of 100 ° C. or higher is preferable. For example, dimethylformamide, N-methyl-2-
Pyrrolidone, dimethylacetamide, dimethylsulfoxide, ethylene glycol monomethyl ether, ethylene glycol monoethyl ether, ethylene glycol monobutyl ether, ethylene glycol dimethyl ether, ethylene glycol diethyl ether, diethylene glycol monomethyl ether, diethylene glycol monoethyl ether, ethylene glycol monomethyl ether acetate, ethylene acetate Glycol monoethyl ether, ethylene glycol monobutyl ether acetate, cyclohexanone and the like can be mentioned. These solvents can be used in combination of two or more kinds.

The curable composition of the present invention has a solid content of 2%.
It is preferably from 50% to 50%, more preferably from 10% to 30%. If the concentration is less than 2%, it is difficult to coat to a predetermined film thickness. If it is 50% or more, the viscosity stability of the composition tends to decrease. By setting the concentration to 30% or less, coatability is further improved.

The curable composition of the present invention is coated on the surface of a colored layer patterned on a transparent substrate. The method of coating is not particularly limited, and examples thereof include a method such as roll coating, spin coating, dip coating, spray coating, and slit die, and it is also possible to form a pattern by a printing method such as offset printing or screen printing.
