Abstract:
A novel benzophenone type polymerizable dye containing a urethane bond and an ophthalmic lens containing the said polymerizable dye are disclosed. The benzophenone type polymerizable dye is shown by the following general formula (1) (wherein R1 and R2 are respectively and independently a hydrogen atom, a hydroxyl group, a carboxylic group, a C1 to C8 alkyl group, a C1 to C8 alkoxy group, a sulfonic acid group or a benzyloxy group, and m and n are respectively and independently an integer of 0 to 18. R3 is any of a polymerizable functional group of a vinyl group, an acryloyl group or a methacryloyl group).
