Title:
METHOD FOR PRODUCING CARBOXY-GROUP-CONTAINING RESIN-CONTAINING SOLUTION AND METHOD FOR STABILIZING CARBOXY-GROUP-CONTAINING RESIN
Document Type and Number:
WIPO Patent Application WO/2022/091905
Kind Code:
A1
Abstract:
Provided are a method for producing a carboxy-group-containing resin-containing solution having excellent stability over time and a method for stabilizing a carboxy-group-containing resin. The method for producing a carboxy-group-containing resin-containing solution of the present invention is characterized by including a step A for reacting a reaction intermediate obtained by reacting an epoxy compound (a) with an unsaturated monobasic acid (b), a polybasic acid dianhydride (c), and a polybasic acid anhydride (d) and synthesizing a first carboxy-group-containing resin-containing solution and a step B for adding water to the first carboxy-group-containing resin-containing solution to obtain a second carboxy-group-containing resin-containing solution.
