PROBLEM TO BE SOLVED: To provide a photocurable composition allowing formation of a cured film being excellent in transparency and heat-resistance and having a high refractive index and high smoothness.SOLUTION: A photocurable composition contains (A) inorganic oxide-coated titanium oxide particles or organic silicon compound-coated titanium oxide particles having a primary particle diameter of 3 to 100 nm, (B) a compound having two or more (meth)acryloyl groups in a molecule, (C) a photopolymerization initiator, (D) a compound shown by the following formula (1) (where Rand R, which are the same or different, represent an alkyl group having a carbon number of 1 to 20, Rrepresents a hydrogen atom, a methyl group or an ethyl group, and m and n are positive integers and m+n=10 to 1,000), and (E) a solvent. The composition is a photocurable composition for a disc coat, where the content of the component (A) is 30 to 85 mass% when the total amount of the components except for the (E) solvent in the composition is 100 mass%. |
