POLYARYLATE RESIN

摘要

An object of the present invention is to provide a polyarylate resin having an adequate ultraviolet-absorbing property and an adequate dissolving property in an organic solvent, which is excellent in a solution stability even when it is dissolved in a polar Organic solvent having a high hygroscopic property and in a reactivity with the other material and adhesive properties to various materials. The present invention provides a polyarylate resin comprising a bisphenol component including a compound shown by a general formula (1) and an aromatic dicarboxylic acid component as monomeric components, wherein the polyarylate resin is satisfied with the formula mentioned below:;ηB/ηA≦0.95 ;(wherein ηA represents an inherent viscosity measured in a concentration of 1 g/dL and a temperature of 25° C. using tetrachloroethane as a solvent and ηB represents an inherent viscosity measured in a concentration of 1 g/dL and a temperature of 25° C. using a mixture liquid of phenol/tetrachloroethane/sodium acetate having a mass ratio of 6/4/0.006 as a solvent):;;(wherein R1 and R2 respectively and independently represent an alkyl group.).
