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

[0223] Examples and comparative examples are listed below to explain the present invention more specifically.

[0224] In addition, hereinafter, "parts" means parts by mass, and "%" means parts by mass.

manufacture example 1

[0225] ○Production Example 1 [Preparation of (a-1)]

[0226] In a 500 ml glass flask equipped with a stirring device, a thermometer, and a water-cooled condenser, 110 g of ethanol and 100 g of an acrylate mixture containing dipentaerythritol penta and hexaacrylate in a ratio of 30:70 (mass ratio) were added [hydroxyl value 36mgKOH / g, hereinafter referred to as "g1"], put 10 g of proline at room temperature and react for 4 hours. The reaction is carried out in an air atmosphere.

[0227] As a result, a solution containing 50% (a-1) (hereinafter referred to as a1) with an acid value of 45 mgKOH / g (converted as solid matter) as a solid matter was obtained.

manufacture example 2

[0228] ○Production Example 2 [Preparation of (a2-1)]

[0229] In the same flask as in Production Example 1, 16 g of succinic anhydride, 250 g of g1, and 0.13 g of mytol-hydroquinone complex were added, and the temperature was raised to 85°C. 1.3 g of triethylamine as a catalyst was put therein, and then reacted for 4 hours. The reaction was carried out in an air / nitrogen mixed atmosphere to obtain a compound having an acid value of 34 mgKOH / g (hereinafter referred to as "h1").

[0230] Next, add 103 g of DMDG [manufactured by Nippon Emulsifier Co., Ltd., trade name DMDG, hereafter referred to as "DMDG"], 100 g of g1, put 2.6 g of ethanolamine at room temperature, and react in an air atmosphere. 4 hours.

[0231] As a result, a solid substance containing 50% (a2-1) (hereinafter referred to as "a2") with an acid value of 33 mgKOH / g (converted to solids) and a hydroxyl value of 23 mgKOH / g (converted to solids) as solids Solution.

[0232] In addition, h1 was also used in Comparative ...

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 inks, paints, and resists and other pattern forming compositions. In particular, since it is excellent in alkali developability, it is preferred as The use of the pattern forming composition belongs to these technical fields. The composition of the present invention is more preferably used especially for the production of liquid crystal display panels. Specifically, it is preferably used for the production of columnar spacers, the production of color filter protective films, and the production of colored layers for color filters. Formation and other uses also belong to these technical fields. Background technique [0002] Conventionally, (meth)acrylates are often used for resists used for etching resists, solder resists, and color resists that form colored layers of color filters. In this case, in or...
