Embodiment

[0180] Hereinafter, an embodiment of the present invention will be described more specifically with reference to examples. However, the present invention is not limited to the following examples.

[0181]

Synthetic example 1

[0183] In a flask equipped with a condenser and a stirrer, 100 parts by mass of propylene glycol monomethyl ether acetate was added and replaced with nitrogen. Heating to 80°C, at this temperature, 50 parts by mass of propylene glycol monomethyl ether acetate, 20 parts by mass of methacrylic acid, 10 parts by mass of styrene, 5 parts by mass of benzyl methacrylate, methacrylic acid -15 parts by mass of 2-hydroxyethyl ester, 23 parts by mass of 2-ethylhexyl methacrylate, 12 parts by mass of N-phenylmaleimide, succinic acid mono(2-acryloyloxyethyl) A mixed solution of 15 parts by mass of the ester and 6 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) was polymerized for 1 hour while maintaining the temperature. Thereafter, the temperature of the reaction solution was raised to 100° C., and polymerization was carried out for 1 hour to obtain a binder resin solution (solid content concentration=40% by mass). Mw of the obtained binder resin was 11200, and Mn was 6000. Thi...

Synthetic example 2

[0185] In a flask equipped with a condenser tube and a stirrer, 25 parts by mass of 3-methacryloxymethyl-3-ethyloxetane, 18 parts by mass of methacrylic acid, succinic acid mono-2-acryloyl 9 parts by mass of oxyethyl ester, 10 parts by mass of N-phenylmaleimide, 24 parts by mass of benzyl methacrylate, and 14 parts by mass of hydroxyethyl methacrylate are dissolved in 300 parts by mass of propylene glycol monomethyl ether acetate 6 parts by mass of 2,2'-azobisisobutyronitrile and 6 parts by mass of 2,4-diphenyl-4-methyl-1-pentene were further added to the parts, followed by nitrogen purge for 15 minutes. ). After nitrogen purging, the reaction liquid was heated to 80°C while stirring and nitrogen bubbling, and polymerized for 5 hours.

[0186] To 200 parts by mass of the obtained copolymer solution, 13.4 parts by mass of 2-methacryloyloxyethyl isocyanate and 0.2 parts by mass of 4-methoxyphenol as a polymerization inhibitor were added and reacted at 90°C. 2 hours. The react...

Abstract

The present invention provides a radiation-sentive colored composition, a color filter and a display device. The radiation-sensitive colored composition can be used for manufacturing the color filter with excellent manufacturing characteristic even lake pigment is used as a colorant. The radiation-sensitive colored composition comprises the following components: (A) a colorant with the lake pigment, (B) an adhesive resin, (C) a photopolymerization initiator, (D) a compound with more than two polymerizable unsaturated keys, and (E) a multifunctional thioalcohol. The radiation-sensitive colored composition is used for forming a pixel pattern (3) on a substrate (2). Furthermore a black matrix (4) and a protective film (5) are configured for manufacturing the color filter (1). The color filter (1) is used for manufacturing a display element.

Description

technical field [0001] The invention relates to a radiation-sensitive coloring composition, a color filter and a display element. Background technique [0002] When producing a color filter using a radiation-sensitive coloring composition, a method is known in which a pigment-dispersed coloring radiation-sensitive composition is coated on a substrate and dried, and then the dried coating film is formed in a desired pattern shape. By irradiating radiation (hereinafter referred to as "exposure") and developing, pixels of each color are obtained (Patent Document 1 to Patent Document 2). Moreover, the method of forming a black matrix (black matrix) using the photopolymerizable composition which disperse|distributed carbon black is also known (patent document 3). [0003] In addition, it is known that it is effective to use a dye as a colorant in order to achieve high brightness and high color purity of a display device, or high definition of a solid-state imaging device. Howev...
