Embodiment 1

[0262] First, a synthesis example of a polymerizable unsaturated group-containing alkali-soluble resin having a structure represented by the general formula (2) and the general formula (15) will be described.

[0263] [Solid content concentration]

[0264] 1 g of the resin solution obtained in the synthesis example and the comparative synthesis example, the photosensitive resin composition, etc. were impregnated in a glass filter [mass: W 0 (g)], and weigh [W 1 (g)], use the following formula (1) to obtain the mass [W 2 (g)].

[0265] Solid content concentration (mass%) = 100 * (W 2 -W 0 ) / (W 1 -W 0 )(1)

[0266] [acid value]

[0267] Dissolve the resin solution in tetrahydrofuran, and titrate with a 1 / 10N-KOH aqueous solution using a potentiometric titration device "COM-1600" (manufactured by Hiranuma Sangyo Co., Ltd.), and use the amount of KOH required per 1 g of the solid content as the acid value .

[0268] [molecular weight]

[0269]For colloid permeation chro...

Synthetic example 1

[0281] Add the 50% PGMEA solution (329.1g) of HBPA-EA1, BPDA (44.1g), THPA (22.8g), TEAB (0.43g), PGMEA (8.5g) in the 1000ml four-neck flask with reflux cooler, Stir at 120 to 125° C. for 6 hours to obtain alkali-soluble resin (i)-1 (solid content concentration: 61.2% by mass, weight average molecular weight (Mw): 3210, acid value (solid content conversion): 123.1 mgKOH / g) .

Synthetic example 2

[0283] Add the 50% PGMEA solution (340.0g), HPMDA (34.7g), THPA (23.6g), TEAB (0.43g), PGMEA (8.5g) of HBPA-EA1 in the 1000ml four-necked flask that attaches reflux cooler, in It stirred at 120 to 125 degreeC for 6 hours, and obtained alkali-soluble resin (i)-2 (solid content concentration: 61.1 mass %, weight average molecular weight (Mw): 3230, acid value (solid content conversion): 120.4 mgKOH / g).

Abstract

The invention relates to an alkali-soluble resin, a hydrogenated compound, a method for producing the hydrogenated compound, a resin composition, a cured film of the resin composition, a touch panel,and an optical filter. Specifically, the present invention relates to a method for producing an alkali-soluble resin containing a polymerizable unsaturated group, the method being capable of obtaininga photosensitive resin composition having a low refractive index and excellent light-resistant development characteristics. The method for producing an alkali-soluble resin containing a polymerizableunsaturated group comprises: reacting a reactant of an epoxy compound (a) having a structure represented by general formula (1) and a monocarboxylic acid containing an unsaturated group with a dicarboxylic acid, a tricarboxylic acid, or a monoanhydride (b) thereof, and a tetracarboxylic acid or a dicarboxylic anhydride (c) thereof.

Description

technical field [0001] The present invention relates to a method for producing an alkali-soluble resin containing a polymerizable unsaturated group, an alkali-soluble resin containing a polymerizable unsaturated group, a hydrogenated compound, a method for producing the same, a photosensitive resin composition, and a process for curing the photosensitive resin composition. A cured film, and a touch panel and a color filter containing the cured film as constituents. Background technique [0002] In recent years, due to the development of portable terminals, display devices such as touch panels and liquid crystal panels used outdoors or in vehicles have increased. In the above-mentioned display device, a light-shielding film is provided on the outer frame of the touch panel to shield light leakage from the peripheral portion of the rear liquid crystal panel, and to suppress light leakage from the screen when the liquid crystal panel displays black, and to suppress the adjacent...
