Description

The present invention relates to colored resin compositions and compounds.

Color filters used in display devices such as liquid crystal display devices, electroluminescence display devices and plasma displays, and solid-state imaging devices such as CCD and CMOS sensors are produced from colored resin compositions. Various colorants are used as the colored resin composition for forming the color filter.

For example, it is known that a perylene compound represented by the following formula (x) can be used as a colorant (Non-Patent Document 1).

However, the perylene compound described above may not have sufficient heat resistance when used as a colored resin composition. Accordingly, an object of the present invention is to provide a colored resin composition and a compound capable of forming a color filter having excellent heat resistance.

[Synthesis Example 4]
A suitable amount of nitrogen was introduced into a flask equipped with a reflux condenser, a dropping funnel and a stirrer to create a nitrogen atmosphere. Then, 38 parts of acrylic acid, 3,4-epoxytricyclo[5.2.1.0 ^2,6 ]decan-8-yl acrylate and 3,4-epoxytricyclo[5.2.1.0 ^{2, 6} ] A mixed solution of 289 parts of a mixture of decane-9-yl acrylate (content ratio is 1:1 in molar ratio) and 125 parts of propylene glycol monomethyl ether acetate was added dropwise over 5 hours.

(A) Colorant: 2.6 parts of compound represented by formula (I-18) (B) Resin: 54 parts of resin B1 solution (E) Solvent: 420 parts of propylene glycol monomethyl ether acetate

(2) Preparation of colored resin composition Subsequently, each component was mixed in the following ratios to obtain a colored resin composition 1.
Colored resin composition 1' 478 parts (C) Polymerizable compound: Dipentaerythritol hexaacrylate (Kayarad (registered trademark) DPHA; manufactured by Nippon Kayaku Co., Ltd.) 40 parts (D) Polymerization initiator: N- benzoyloxy - 1-(4-phenylsulfanylphenyl) octan-1-one-2-imine (Irgacure (registered trademark) OXE 01; manufactured by BASF) 2 parts (F) Leveling agent: polyether-modified silicone oil (Toray silicone SH8400: Toray・ Dow Corning Co., Ltd.) 0.15 parts

(3) Preparation of colored coating film On a 5 cm square glass substrate (Eagle XG; manufactured by Corning Incorporated), colored fat composition 1 was spin-coated so that the film thickness after post-baking was 1.7 to 2 µm. and then prebaked at 100° C. for 3 minutes to form a colored resin composition layer. After allowing to cool, the colored resin composition layer formed on the substrate was exposed using an exposure machine (TME-150RSK; manufactured by Topcon Corporation) in an air atmosphere at an exposure amount of 80 mJ/cm ² (365 nm standard). irradiated with light. After light irradiation, post-baking was performed in an oven at 230° C. for 30 minutes to obtain a colored coating film.

(4) Measurement of λ _max The absorbance of the obtained colored coating film was measured using a colorimeter (OSP-SP-200; manufactured by OLYMPUS). The maximum absorbance wavelength (λ _max ) was calculated as the maximum absorbance wavelength between 380 and 780 nm.

(5) Heat resistance test The resulting colored coating film was heated in an oven at 230°C for 120 minutes in an air atmosphere. The color difference ΔE ^* ab was calculated from the xy chromaticity coordinates (x, y) before and after the test and the Y measurement value by the method described in JIS Z 8730:2009 (7. Color difference calculation method). It means that the smaller the color difference ΔE ^* ab, the smaller the color change ^. Moreover, if the heat resistance of the colored coating film is good, the colored pattern produced from the same colored resin composition can also be said to have good heat resistance.
