Synthetic example 1

[0099] In an autoclave equipped with a thermometer, a nitrogen gas introduction device, an alkylene oxide introduction device and a stirring device, a polyphenol resin (manufactured by Japan Epoxy Resin Co., Ltd., trade name: "EPICYUA-YL6065", 98 parts of OH equivalent: 98), 0.98 parts of potassium hydroxide and 98 parts of toluene, the reaction system was replaced with nitrogen under stirring, and the temperature was raised by heating. Subsequently, 63.8 parts of propylene oxide was slowly dropped into it, and at 125 to 132 ° C, 0 to 4.8 kg / cm 2 The reaction was carried out for 16 hours. Thereafter, after cooling to room temperature, 1.28 parts of 89% phosphoric acid was added to the reaction solution, mixed, and neutralized with potassium hydroxide to obtain a polyphenol with a non-volatile content of 63.8% and a hydroxyl equivalent of 160.7 g / eq. Propylene oxide reaction solution of the resin. This is obtained by adding an average of 1.08 moles of epoxy per 1 equivalent o...

[0104] In the autoclave with a thermometer, a nitrogen introduction device, an alkylene oxide introduction device and a stirring device, add 98 parts of polyphenol resin (manufactured by Japan Epoxy Resin Co., Ltd., trade name "EPIQUA-YL6065", OH equivalent: 98), hydrogen 0.98 parts of potassium oxide and 98 parts of toluene were used, and the reaction system was replaced with nitrogen while stirring, and the temperature was raised by heating. Subsequently, 174.0 parts of propylene oxide was slowly dropped into it, and at 125 to 132 ° C, 0 to 4.8 kg / cm 2 The reaction was carried out for 16 hours. Thereafter, after cooling to room temperature, 1.28 parts of 89% phosphoric acid was added to the reaction solution, mixed, and neutralized with potassium hydroxide to obtain a polyphenol with a non-volatile content of 75.1% and a hydroxyl equivalent of 264.5 g / eq. Propylene oxide reaction solution of the resin. This is obtained by adding an average of 2.87 moles of epoxy per 1 equi...

[0108] In an autoclave equipped with a thermometer, a nitrogen gas introduction device, an alkylene oxide introduction device and a stirring device, polyparahydroxystyrene resin (manufactured by Maruzen Petrochemical Co., Ltd., trade name "Maerca-M", OH equivalent: 120) was added. 120 parts, 1.2 parts of potassium hydroxide and 120 parts of toluene, the reaction system was replaced with nitrogen under stirring, and the temperature was raised by heating. Subsequently, 63.8 parts of propylene oxide was slowly dropped into it, at 125 to 132 ° C, 0 to 4.8 kg / cm 2 The reaction was carried out for 16 hours. Thereafter, after cooling to room temperature, 1.57 parts of 89% phosphoric acid was added to the reaction liquid, mixed, and neutralized with potassium hydroxide to obtain poly-p-hydroxyl with 62.0% non-volatile content and 182 g / eq. Propylene oxide reaction solution of styrene resin. This is obtained by adding an average of 1.07 moles of epoxy per 1 equivalent of phenolic hyd...

Abstract

There is provided a curable resin having an unsaturated group and a carboxyl group at the terminals of its side chains, such as a curable resin obtained by reacting an unsaturated group-containing monocarboxylic acid (d) with a reaction product (c) of a compound having three or more phenolic hydroxyl groups in its molecule (a) and an alkylene oxide (b) and further reacting a polybasic acid anhydride (f) with the resultant reaction product (e). By compounding such a curable resin with a photopolymerization initiator, a photosensitive (meth)acrylate compound, an epoxy compound, a diluent solvent, another curable resin which has a carboxyl group and an unsaturated group in its molecule and which is in the state of solid at room temperature, a flame-retardant, etc., there is obtained a photocurable and thermosetting resin composition which is useful for the formation of a solder resist of a printed circuit board, an interlaminar insulating layer of a multi-layer circuit board, or the like.

Description
