Ophthalmic lens material |
| abstract |
(57) [Abstract] [Purpose] To provide an ophthalmic lens material which is excellent not only in ultraviolet absorption but also in stain resistance and mechanical strength. [Structure] General formula (I): [Wherein R 1 and R 2 may be the same or different and each represents a hydrogen atom or a methyl group, and A is a perfluoroalkyl group having 1 to 8 carbon atoms or a general formula: {In the formula, R 3 and R 4 may be the same or different, and are represented by the general formula: — (CH 2 ) n —C p F 2 2 p + 1 (wherein n is an integer of 0 to 8 and p is an integer of 1 to 8) or a hydrogen atom (provided that R 3 and R 4 are not both hydrogen atoms) )} And a fluorine-containing maleimide compound represented by the formula: m is an integer of 0 to 3]. |
