A polyolefin resin composition having excellent transparency which comprises a polyolefin resin having a melt flow rate (MFR) at 230&#xb0; C. of 20 dg/min or more, (A) a dibenzylidene sorbitol compound represented by the following general formula (1), (wherein n represents an integer of 0 to 2; and R, R, R, R, and Reach independently represent a hydrogen atom or the like) and (B) an alkali metal salt compound of organic phosphoric acid ester represented by the following general formula (2), (wherein Rto Reach independently represent a hydrogen atom or the like), and wherein the sum of the amount of the component (A) and the component (B) is 0.01 to 1.0 part by mass per 100 parts by mass of the polyolefin resin, and (A)/(B), the ratio (mass ratio) between the component (A) and the component (B), is within a range from 99/1 to 80/20.

Polyolefin resin composition

Disclosed is an optical film characterized by containing 0.001-10 parts by mass of an ultraviolet absorbent represented by general formula (1) per 100 parts by mass of a cellulose ester. (In the formula, n represents an integer of 1-4; when n is 1, R represents an alkyl group having 3-30 carbon atoms, and when n is 2-4, R represents a residue obtained by removing a carboxylic acid group from an aliphatic or aromatic polybasic acid having 1-34 carbon atoms; and R1, R2, R3 and R4 independently represent a hydrogen atom or an alkyl group having 1-4 carbon atoms.)
