Abstract
The present invention provides an optical film, which is excellent in ultraviolet absorption capability at 380 nm with little bleed-out, comprising a resin containing a triazine compound represented by the following general formula (I).(In the formula, R1-R6 may be a hydrogen atom; hydroxyl group; or an organic group selected from among an alkyl group, alkoxy group, dialkyl amino group, alkyl carbonyloxy group, aryl group, arylated alkyl group, aryloxy group, arylated alkyloxy group and an aryl carbonyloxy group having 18 or less carbon atoms, independently. However, the alkyl part of these organic groups may be substituted by a hydroxyl group, halogen atom, cyano group or nitro group, interrupted by an oxygen atom, sulfur atom, carbonyl group, ester group, amide group or imino group, or have a double bond, and these substitutions, interruptions and double bonds may be combined).
