AQUEOUS FIBROIN SOLUTION AND PRODUCTION METHOD THEREOF, AND ARTICLE COMPRISING FIBROIN

WIPO Patent Application WO/2023/190130

A1

Provided is an aqueous fibroin solution having high storage stability and excellent foam formation ability, and a production method thereof. This aqueous fibroin solution contains fibroin and a compound represented by general formula (1) or (2). In general formula (1): R1 to R4 independently represent a hydrogen atom, an optionally substituted aliphatic hydrocarbon group having 1 to 8 carbon atoms, or an optionally substituted aryl or aralkyl group having 6 to 10 carbon atoms, provided that at least one of R1 to R4 is not a hydrogen atom; and X- represents an anion. In general formula (2): C-N=C and A together form a cyclic structure; R5 represents a hydrogen atom, an optionally substituted aliphatic hydrocarbon group having 1 to 8 carbon atoms, or an optionally substituted aryl or aralkyl group having 6 to 10 carbon atoms; and X- represents an anion.
