Abstract:
The present invention can provide a polyarylate obtained from a dihydric phenol component and an aromatic dicarboxylic acid component. The polyarylate is characterized in that the dihydric phenol component contains a compound represented by general formula (A) or (B) as a primary raw material, and the pencil hardness of the polyarylate is H or higher. (In the formula, R1 and R2 each independently denote a hydrogen atom, an alkyl group having 1-6 carbon atoms or a phenyl group. However, neither R1 nor R1 represents a methyl group.) (In the formula, R3 and R4 each independently denote a hydrogen atom or a methyl group. In addition, a is an integer between 4 and 11. However, a is not 5 if R3 and R4 are both hydrogen atoms.)
