Abstract
A photocurable composition contains at least one ultraviolet absorber represented by Formula (1), and a hard coating agent including the photocurable composition.wherein R1, R2 and R3 may be the same as or different from each other and represent a branched or linear alkyl group with 1-20 carbon atoms and is substituted with a (meth)acryloyloxy group; the alkyl group may be substituted with a hydroxyl group, an alkoxy group having 1-8 carbon atoms, or an acyloxy group having 1-8 carbon atoms; the alkyl group may be interrupted by an oxygen atom, a sulfur atom, a carbonyl group, an ester group, an amide group, or an imide group; and R4, R5 and R6 may be the same as or different from each other and represent a hydrogen atom, a halogen atom, a hydroxyl group, an alkyl group having 1-12 carbon atoms, or an alkoxy group having 1-12 carbon atoms.
