Title:
ALKALI-SOLUBLE RESIN, ALKALI-SOLUBLE RESIN COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2023/182273
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide: an alkali-soluble resin and an alkali-soluble resin composition, each of which is capable of forming a cured product that has excellent thermal coloring resistance and a high refractive index; and a production method by which these can be obtained efficiently. The present invention provides an alkali-soluble resin which has a structure represented by formula (1); and this alkali-soluble resin is characterized in that the content of an ammonium salt compound is 0.06% by mass or less relative to 100% by mass of the alkali-soluble resin. (In formula (1), R1, R2 and R3 may be the same or different and each represents a hydrogen atom or a hydrocarbon group having 1 to 6 carbon atoms; R4 represents a direct bond or a divalent organic group; R5, R6, R7 and R8 may be the same or different and each represents a hydrogen atom or Y, and at least one of the R5 to R8 moieties represents Y; Y represents a group represented by formula (2); R9 and R10 may be the same or different and each represents a substituent; W represents a divalent organic group; X represents a direct bond or a divalent organic group; l represents the number of the R9 moieties, the number being an integer of 0 to 4; m represents the number of the R10 moieties, the number being an integer of 0 to 4; in cases where there are a plurality of R9 moieties and a plurality of R10 moieties, the moieties may be the same as or different from each other, respectively; and n represents an integer of 1 or more.) (In formula (2), R11 represents an optionally substituted divalent organic group.)
