Inventors: Inukai, Hiroshi; Kitahara, Takahiro;
Assignee: Daikin Industries, Ltd. (Osaka, JP)
Primary Examiner: McCamish; Marion E.
Assistant Examiner: Berman; Susan
Attorney, Agent or Firm: Larson and Taylor
This invention provides: (1) a hard coating agent of low refractive index comprising an unsaturated double bond-containing ester compound having fluorine-containing organic group, an unsaturated double bond-containing compound having alkoxysilyl group and a photopolymerization initiator; and (2) a hard coating agent of low refractive index comprising a copolymer prepared by copolymerizing the unsaturated double bond-containing ester compound having fluorine-containing organic group and the unsaturated double bond-containing compound having alkoxysilyl group. |

DETAILED DESCRIPTION We claim: 1.
A curable composition for producing a hard coating of low refractive index consisting essentially of (a) about 30 to about 95% by weight of an unsaturated double bond-containing ester compound represented by the formula ##STR13## wherein R.
sup.
1 is a fluorine atom, X is (CH.
sub.
2).
sub.
p (wherein p is an integer of 1 to 3), ##STR14## (wherein Y is hydrogen atom or ##STR15## (q is an integer of 1 to 4 and r is an ##STR16## wherein R.
sup.
1 is fluorine atom, X is (CH.
sub.
2).
sub.
p (wherein p is an integer of 1 to 3), ##STR17## (wherein Y is hydrogen atom or ##STR18## (q is an integer of 1 to 4 and r is an integer of 0 to 3), and R.
sup.
2 is fluorine-containing alkyl group, alkenyl group or ether group, and (b) about 70 to about 5% by weight of a compound represented by the formula ##STR19## wherein R.
sup.
3 is hydrogen atom, fluorine atom, chlorine atom or methyl group, R.
sup.
4 is alkyl group, fluorine-containing alkyl group or cycloalkyl group, R.
sup.
5 is alkyl group having 1 to 4 carbon atoms, t is 0 or 1, m is an integer of 0 t 4, and n is an integer of 1 to 3.
2.
The hard coating agent according to claim 1 which contains about 50 to about 90% by weight of the (a) compound and about 50 to about 10% by weight of the (b) compound, based on the combined amount of the (a) compound and the (b) compound.
3.
The hard coating agent according to claim 1 which contains about 0.
5 to about 10% by weight of the (c) photopolymerization initiator, based on the combined amount of the (a) compound and the (b) compound.
4.
The hard coating agent according to claim 1 which contains about 1 to about 5% by weight of the (c) photopolymerization initiator, based on the combined amount of the (a) compound and the (b) compound.
5.
The hard coating agent according to claim 1 wherein R.
sup.
2 in the compound of the formula (I) is fluorine-containing alkyl group having 1 to 20 carbon atoms.
6.
The hard coating agent according to claim 1 wherein R.
sup.
3 in the compound of the formula (II) is fluorine atom or methyl group, R
