| 摘要 |
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, R 1 and R 2 each independently denote a hydrogen atom, an alkyl group having 1-6 carbon atoms or a phenyl group. However, neither R 1 nor R 2 represents a methyl group.)
(In the formula, R 3 and R 4 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 R 3 and R 4 are both hydrogen atoms.) |
