Abstract:
A polyarylate resin includes at least one type of repeating unit represented by a general formula (1), at least one type of repeating unit represented by a general formula (2), and a terminal group represented by a general formula (3). R1, R2, R3, and R4 each represent, independently of one another, a hydrogen atom or a methyl group. R5 and R6 each represent, independently of each other, a hydrogen atom or a C1-4 alkyl group. R5 and R6 may bond together to represent a C5-7 cycloalkylidene group. X1 represents a divalent group represented by a chemical formula (2A), (2B), (2C), or (2D) with the proviso that when only one type of repeating unit represented by the general formula (2) is included, X1 does not represent a divalent group represented by the chemical formula (2D). Rf represents a chain aliphatic group having at least one fluoro group.
