Abstract: The present invention provides a polyarylate resin which is excellent in heat-resisting properties, abrasion-resisting properties, solubility properties in non-halogenated organic solvents, a water vapor-barrier property, mechanical properties, liquid sag-resisting properties and deformation-resisting properties (such as adhesive properties). The present invention relates to a polyarylate resin comprising a dihydric phenol residue shown in general formula (1) and an aromatic dicarboxylic acid residue shown in general formula (2), a film comprising the same and a laminated product thereof: (wherein X represents a liner or branched bivalent hydrocarbon group having 4 to 8 carbon atoms.) (wherein R1 and R2 respectively and independently represent a monovalent hydrocarbon group having 1 to 6 carbon atoms, which may be substituted by one or more halogen atoms, or a halogen atom, and p and q respectively and independently represent an integer of 0 to 4.).
