Claim 2:
3. The photocurable composition according to claim 2,
wherein (b) additive having a photoreactive functional group includes at least one selected from the group consisting of an additive represented by General Formula (1) and an additive containing a structure represented by General Formula (2):, in General Formula (1),
R1's are the same or different from one another and represent any atom or group selected from the group consisting of a hydrogen atom, a fluorine atom, a halogen atom, a hydrocarbon group having 1 to 20 carbon atoms, an aryl group having 6 to 20 carbon atoms, an aralkyl group having 6 to 20 carbon atoms, a polyether group having 1 to 20 carbon atoms, and a fluorocarbon group having 1 to 20 carbon atoms,
at least one of L1's contains a photoreactive functional group selected from the group consisting of an epoxy group, a hydroxyl group, an amino group, a vinyl ether group, a lactone group, a propenyl ether group, an olefin group, an oxetanyl group, a vinyl group, an acrylate group, a carbinol group, and a carboxy group, and in a case where L1 is not a photoreactive functional group, L1's are the same or different from one another and represent an atom or group selected from the above-mentioned R1, and
n and 1-n represent a ratio of each unit,, in General Formula (2), L2 is a photoreactive functional group selected from the group consisting of an epoxy group, an amino group, a vinyl ether group, a lactone group, a propenyl ether group, an alcohol group, an olefin group, an oxetanyl group, a vinyl group, an acrylate group, a carbinol group, and a carboxy group,
at least one of R2 to R5 is a fluorine-containing group selected from the group consisting of fluorine, a fluorine-containing alkyl group having 1 to 10 carbon atoms, a fluorine-containing alkoxy group having 1 to 10 carbon atoms, and a fluorine-containing alkoxyalkyl group having 2 to 10 carbon atoms,
in a case where R2 to R5 are not fluorine-containing groups, R2 to R5 are organic groups selected from the group consisting of hydrogen, an alkyl group having 1 to 10 carbon atoms, an alkoxy group having 1 to 10 carbon atoms, and an alkoxyalkyl group having 2 to 10 carbon atoms,
R2 to R5 may be the same or different from one another, and R2 to R5 may be bonded to each other to form a ring structure, and
a dotted line indicates that a bond of the portion thereof may be a carbon-carbon single bond or a carbon-carbon double bond.
