Problems solved by technology

[0005] However, color filters that use conventional colored cured products containing dyes and are baked at low temperatures have disadvantages in that they are poor in heat resistance and solvent resistance.
In addition, since the curing reactivity is not sufficient, the resulting color filter is not satisfactory in terms of development resistance, voltage retention, etc.
Therefore, it is also considered to add an amine compound that can be used as a curing agent for epoxy-based materials, so that the crosslinking reaction can be carried out even at low temperatures. Time-dependent reaction of existing epoxy groups, decreased storage stability

Embodiment

[0395] Hereinafter, although this invention is demonstrated in full detail based on an Example, this Example is not limited to interpreting this invention.

[0396]

Synthetic example 1

[0398] Into a flask with a condenser tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 220 parts by mass of diethylene glycol methyl ethyl ether were added. Continue to add 12 mass parts methacrylic acid as (A1) compound, 40 mass parts glycidyl methacrylate as (A2) compound, 20 mass parts styrene as (A4) compound and 28 mass parts trimethacrylate ring [5.2.1.0 2，6 ] dec-8-ester, carry out nitrogen replacement, and while slowly stirring, raise the solution temperature to 70° C., keep the temperature for 5 hours, and carry out polymerization, thereby obtaining a solution containing the copolymer (A-1). The solid content concentration of the obtained polymer solution was 31.3% by mass, and the Mw of the copolymer (A-1) was 12,000.

Synthetic example 2

[0400] Into a flask with a condenser tube and a stirrer, 5 parts by mass of 2,2'-azobis(2,4-dimethylvaleronitrile) and 220 parts by mass of diethylene glycol methyl ethyl ether were added. Continue to add 18 mass parts methacrylic acid as (A1) compound, 14 mass parts 2-methylglycidyl methacrylate and 20 mass parts glycidyl methacrylate as (A2) compound, and as (A4) 10 mass parts of styrene, 23 mass parts of methacrylic acid tricyclic [5.2.1.0 2，6 ] Dec-8-ester and 15 parts by mass of methyl methacrylate, carry out nitrogen replacement, then slowly stir while raising the solution temperature to 70°C, keep the temperature for 5 hours, and carry out polymerization, thus obtaining a copolymer containing Solution of (A-2). The solid content concentration of the obtained polymer solution was 31.5% by mass, and the Mw of the copolymer (A-2) was 10,100.

Abstract

The present invention aims to provide a colored composition which causes coexistance of storage stability and low-temperature sintering; a colored pattern with high developing resistance, high heat resistance, high solvent resistance, high voltage retaining rate, etc.; a color filter; a color display device with the color filter; and a process for producing the color filter. The colored composition comprises the following components: a copolymer which comprises (A1) a carboxyl structure unit and (A2) an epoxy group structure unit; [B] polymeric compound with ethylene unsaturated key; [C] radiation-sensitive polymerization initiator; [D] colorant; and [E] at least one curing agent which is selected from compound represent by a formula (1), compound represented by a formula (2), tertiary amine compound, ammonium salt, phosphate salt, amidine salt, amide compound, mercaptan compound, blocked isocyanate compound, and a compound with imidazole ring.

Description

technical field [0001] The present invention relates to a coloring composition, a coloring pattern, a color filter, a color display element, and a method for manufacturing the color filter. Background technique [0002] As a method for producing a color filter using a coloring composition, it is known to apply a pigment-dispersed coloring composition on a substrate, dry it, and then irradiate (expose) the coating film with radiation through a mask pattern to develop it. Thereby, a method of obtaining pixels of each color (refer to Patent Documents 1 and 2). [0003] In addition, in order to achieve high contrast of liquid crystal display elements and high definition of solid-state imaging elements, it is effective to use dyes as colorants (see Patent Documents 3 to 5). In the dye-containing coloring composition, a curing system in which a polyfunctional acrylate, an alkoxymethylmelamine resin, etc. are mixed with a polymerization initiator is mainly used. [0004] On the o...
