Problems solved by technology

[0003] At this time, there are problems as follows: polyfunctional (meth)acrylate is insoluble in alkali, and film residue occurs in the uncured part of the coating film during development, and sufficient resolution cannot be obtained. Carboxyl group-containing polyfunctional (meth)acrylates obtained by addition of acyl group compounds to dicarboxylic acid anhydrides
However, according to this composition, although the alkali solubility is improved by using a compound having one carboxyl group in one molecule, the sensitivity is not sufficient in addition to being practically insufficient.

manufacture example 2

[0179] (1) Esterification reaction

[0180] Except that the raw material acrylic acid was set to 683 g (9.48 mol), esterification reaction was carried out in accordance with Production Example 1 in all cases.

[0181] (2) Neutralization treatment

[0182] All were neutralized according to Production Example 1.

[0183] (3) Washing treatment

[0184] All were washed with water according to Production Example 1. An acrylate (hydroxyl value: 72 mgKOH / g) was obtained.

Abstract

Disclosed is an active energy ray-curable composition which exhibits high exposure sensitivity and good developability, thereby enabling to form a precise and accurate pattern when used as an active energy ray-curable pattern-forming composition. This active energy ray-curable composition is excellent in various physical properties such as coating film strength, heat resistance and chemical resistance after it is cured. The active energy ray-curable composition contains, as essential components, a compound (a) wherein an acid anhydride is added to a compound having three or more (meth)acryloyl groups and a hydroxyl group, and a compound (b) wherein a hydroxyl group in a compound having three or more (meth)acryloyl groups and a hydroxyl group is added to at least one (meth)acryloyl group of the component (a) by Michael addition.

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 of pattern-forming compositions such as inks, paints, and photoresists. In particular, it can be preferably used because of its excellent alkali developability. Use as a composition for pattern formation belongs to these technical fields. Background technique [0002] Conventionally, (meth)acrylates are often used as pattern-forming compositions used for etching resists, solder resists, and color resists for forming colored layers of color filters. In this case, a compound having two or more (meth)acryloyl groups (hereinafter referred to as a multifunctional (meth)acrylate) is generally used for the purpose of improving the sensitivity of the composition and increasing the hardness of a cured product. [0003] At this time, there is the following problem: polyfunctional (meth)acrylate is insoluble in a...
