Document Type and Number:
WIPO Patent Application WO/2023/074527
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: a crystalline composition comprising a benzoxazine compound represented by general formula (1); and a method for producing same. As a solution, provided is a crystalline composition comprising a benzoxazine compound represented by general formula (1). (In the formula, each R is independently a hydrogen atom or a methyl group.)
