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).

Abstract: An object of the present invention is to provide a plasticizer having excellent press coloration resistance and cold resistance, and a vinyl chloride resin composition containing the plasticizer. The plasticizer is a trimellitic acid triester plasticizer containing a triester compound of a saturated aliphatic alcohol and trimellitic acid, wherein the saturated aliphatic alcohol contains a linear alcohol having 8 to 10 carbon atoms and a branched alcohol having 8 to 10 carbon atoms, and the ratio (mass ratio) of the linear alcohol and the branched alcohol is 78/22 to 50/50.

Abstract: Provided are: a resin modifier with which flexibility, transparency and bleed resistance can be balanced at a high level; a resin composition; and a film using the same. The resin modifier includes a random copolymer composed of a structural unit derived from an aliphatic dibasic acid, a structural unit derived from an alkylenediol, and a structural unit derived from a polyalkylene ether glycol, which random copolymer has a hydroxyl group or a carboxyl group at a terminal. The polyalkylene ether glycol is preferably a polyethylene ether glycol, and the alkylenediol is preferably at least one selected from the group consisting of ethylene glycol, 1,2-propylene glycol, 1,3-propanediol, 2-methyl-1,3-propanediol, 1,3-butanediol, 1,4-butanediol, neopentyl glycol, 3-methyl-1,5-pentanediol, and hexanediol.
