Problems solved by technology

However, this composition has improved alkali solubility due to the use of a compound containing one carboxyl group per molecule, but especially when the content of the alkali-soluble resin is small, the developability is insufficient, and the sensitivity is also insufficient.

Embodiment

[0224] Examples and comparative examples are given below to describe the present invention more specifically.

[0225] In addition, hereinafter, "part" means a mass part, and "%" means a mass %.

manufacture example 1

[0226] ○ Production Example 1 [Preparation of (a-1)]

[0227] In a 500-milliliter glass flask equipped with a stirring device, a thermometer, and a water-cooled condenser, add 110 g of ethanol, 100 g of an acrylate mixture containing dipentaerythritol five and six acrylates in a ratio of 30:70 (mass ratio) [hydroxyl value 36 mgKOH / g, hereinafter referred to as "g1"], drop into 10g proline at room temperature, and react for 4 hours. The reaction was carried out under air atmosphere.

[0228] As a result, a solution containing 50% (a-1) (hereinafter referred to as a1) having an acid value of 45 mgKOH / g (in terms of solid content) as a solid was obtained.

manufacture example 2

[0229] ○ Production Example 2 [Preparation of (a2-1)]

[0230] In the same flask as in Production Example 1, 16 g of succinic anhydride, 250 g of g1, and 0.13 g of a methalone-hydroquinone complex were charged, and the temperature was raised to 85°C. 1.3 g of triethylamine was thrown in as a catalyst, and it was made to react for 4 hours. The reaction was performed in a mixed atmosphere of air / nitrogen to obtain a compound having an acid value of 34 mgKOH / g (hereinafter referred to as "h1").

[0231] Next, in another flask, add 103 g of DMDG [manufactured by Nippon Emulsifier Co., Ltd., trade name DMDG, hereinafter referred to as "DMDG"], 100 g of g1, put 2.6 g of ethanolamine at room temperature, and react under air atmosphere 4 hours.

[0232] As a result, 50% (a2-1) (hereinafter referred to as "a2") having an acid value of 33 mgKOH / g (in terms of solid matter) and a hydroxyl value of 23 mgKOH / g (in terms of solid matter) was obtained as a solid matter. solution.

Abstract

To provide an actinic-energy-ray-curable composition which, when used as a composition for pattern formation, has high sensitivity to exposure light and satisfactory developability and can form a fine precise pattern and which after curing is excellent in various properties including film strength, heat resistance, and chemical resistance; a composition for pattern formation which, when used in color filter formation in liquid-crystal panel production, not only has those performances but, after curing, has high elasticity and an elastic behavior which makes the cured composition suitable for use as columnar spacers and a protective film; and a coloring composition which, when used, e.g., for forming pixels of a color filter, gives a colored layer reduced in color unevenness and contrast unevenness. [MEANS FOR SOLVING PROBLEMS] The actinic-energy-ray-curable compositions contain as an essential ingredient a compound (a) having two or more ethylenically unsaturated groups, a tertiary amine group, and an acid group.

Description

technical field [0001] The present invention relates to an active energy ray-curable composition. The composition of the present invention can be used in various applications such as a pattern-forming composition such as ink, paint, and resist, and is particularly preferable as an active energy ray-curable composition because it is excellent in alkali developability. The use of the composition for pattern formation belongs to these technical fields. The composition of the present invention is more preferably used in the manufacture of liquid crystal display panels, specifically, it is preferably used in the manufacture of columnar spacers, the manufacture of color filter protective films, and the formation of colored layers for color filters. Uses such as forming also belong to these technical fields. Background technique [0002] Conventionally, (meth)acrylates have been often used as resists used in etching resists, soldering resists, color resists for forming colored lay...
