An ultraviolet-curable composition of the present invention includes epoxy (meth)acrylate, urethane (meth)acrylate, and a silicone compound represented by formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ(CH 3 ) 3 Si-O-X-O-Si(CH 3 ) 3 €ƒ€ƒ€ƒ€ƒ€ƒ(1)
wherein X represents a group having a structure in which n structural units represented by formula (2):
wherein R 1 represents an alkylene group of 1 to 18 carbon atoms, and a divalent group connected with one, or two or more groups selected from divalent groups having a structure in which plural alkylene groups of 2 to 18 carbon atoms are connected through an ether bond, R 1 may be bonded directly to Si or bonded through an oxygen atom to Si, and R 2 represents a hydrogen atom or a methyl group, and
m structural unit represented by formula (3):
are connected in a random or blocked shape, provided that n is an integer within a range from 1 to 15 and n/m is within a range from 1/5 to 1/20. |
