manufacture example 1

[0532]

[0533] Carbon black was produced by the usual oil furnace method. Among them, ethylene tar with low Na, Ca, and S contents was used as a raw material oil, and gaseous fuel was used for combustion. In addition, production was performed using pure water treated with an ion exchange resin as reaction-terminated water. 540 g of the obtained carbon black was stirred together with 14500 g of pure water for 30 minutes at 5,000 to 6,000 rpm using a homogenizer to obtain a slurry. This slurry was transferred to a container with a screw type mixer, and while mixing at about 1,000 rpm, 600 g of toluene in which 60 g of epoxy resin "Epikote 828" (manufactured by Mitsubishi Chemical Corporation) was dissolved was added in small portions. After about 15 minutes, the entire amount of carbon black dispersed in water was transferred to the toluene side, forming particles of about 1 mm.

[0534] Next, after dehydrating with a 60-mesh metal mesh, it put into a vacuum drier, dried at...

[0536] With respect to 20 parts by mass of the coated carbon black prepared in Production Example 1, 4.4 parts by mass of Disperbyk-167 (manufactured by BYK-Chemie) as a dispersant and 1 part by mass of S12000 (manufactured by Lubrizol) as a pigment derivative were added , and propylene glycol monomethyl ether acetate (PGMEA) was added so that the solid content concentration became 35% by mass.

[0537] This was fully stirred with a stirrer and premixed. Next, dispersion treatment was carried out in the range of 25 to 45° C. for 6 hours using a paint shaker, 0.5 mmφ zirconia beads were used as beads, and 60 g of the dispersion liquid and 180 g of beads were added. After the dispersion was completed, the beads and the dispersion liquid were separated by a filter to produce an ink (a1).

[0541] Add 50g of the epoxy compound (epoxy equivalent weight 264) of the above structure, 13.65g of acrylic acid, 60.5g of methoxybutyl acetate, 0.936g of triphenylphosphine and 0.032g of p-methoxyphenol into a mixer equipped with a thermometer and agitator. and a condenser tube, the reaction was carried out at 90° C. while stirring until the acid value became 5 mgKOH / g or less. The reaction took 12 hours and an epoxy acrylate solution was obtained.

[0542] 25 parts by mass of the above epoxy acrylate solution, 0.76 parts by mass of trimethylolpropane (TMP), 3.3 parts by mass of biphenyltetracarboxylic dianhydride (BPDA), 3.5 parts by mass of tetrahydrophthalic anhydride (THPA) It was added to the flask equipped with the thermometer, the stirrer, and the condenser, and it heated up gradually to 105 degreeC, stirring, and it reacted.

Abstract

The present invention provides a substrate with a light-blocking material, which achieves excellently low reflectivity, while having good productivity. The substrate of the present invention is a substrate with a light-blocking material, which comprises a light-blocking material on a transparent substrate. The light-blocking material contains (A) a colorant and (B) an organic binder, and satisfies the following requirements (1) and (2). (1) The light-blocking material contains (C) fine particles having a refractive index of from 1.2 to 1.8 (inclusive). (2) The concentration of the fine particles in the light-blocking material differs in the thickness direction, and the concentration on the side opposite to the transparent substrate side is lower than the concentration on the transparent substrate side.

Description

technical field [0001] The invention relates to a substrate with a light-shielding material, a color filter and a liquid crystal display device. Specifically, it relates to a substrate with a light-shielding material having low reflectance and excellent light-shielding properties, a colored resin composition for forming the light-shielding material, and a color filter and a liquid crystal display device having the light-shielding material. Background technique [0002] Conventionally, as a method of manufacturing a color filter using a pigment, a dyeing method, an electrodeposition method, an inkjet method, a pigment dispersion method, and the like are known. [0003] In the case of producing a color filter by the pigment dispersion method, it is generally carried out as follows: a binder resin, a photopolymerization initiator, a photopolymerizable monomer are added to a colored resin composition obtained by dispersing a pigment with a dispersant or the like etc. to obtain ...
