Abstract: Provided are: a thermal stabilizer composition which does not generate an odor of a phosphorus-based antioxidant; and a synthetic resin composition comprising the same. The thermal stabilizer composition comprises: 100 parts by mass of a phosphorus-based antioxidant having a phosphite structure; and 0.001 to 10 parts by mass of a phenolic antioxidant having a substructure represented by the following Formula (1): (wherein, R1, R2, R3 and R4 each independently represent a hydrogen atom or a hydrocarbon group having 1 to 10 carbon atoms; a represents an integer of 0 to 2; and, when a is 2, plural R3s are optionally the same or different).

Abstract: Disclosed is a stretched optical compensation film which is a phase difference film containing a cellulose-based resin and having excellent optical properties. The stretched optical compensation film of the present invention contains 0.5 to 30 parts by mass of a β-diketone compound represented by Formula (I) with respect to 100 parts by mass of the cellulose-based resin. Positions R1 and R2 each independently represent an alkyl group having 1 to 20 carbon atoms which is optionally substituted, an arylalkyl group having 7 to 20 carbon atoms which is optionally substituted or an aryl group having 6 to 20 carbon atoms which is optionally substituted. Position R3 represents a hydrogen atom or an alkyl group having 1 to 10 carbon atoms.

Abstract: Provided are: a retardation-increasing agent that has excellent compatibility and, when incorporated into a resin film, is capable of not only adjusting the thickness-direction phase difference toward a positive direction but also imparting the film with high retardation; a cellulose-based resin composition comprising the retardation-increasing agent; and a film that is obtained from the cellulose-based resin composition and has excellent optical properties. The retardation-increasing agent comprises a compound represented by the following Formula (1) or (2): (wherein, R1 to R10 each independently represent a hydrogen atom or the like); or (wherein, R21 to R28 each independently represent a hydrogen atom or the like).
