Polymerizable alicyclic esters represented by formula (1) or (2), wherein rings A, B, C, D, and E each represents a nonaromatic carbon ring; R represents a polymerizable unsaturated group; and R?a1, Rb1, and Rc1¿ are the same or different and each represents hydrogen, a hydroxyl group optionally protected by a protective group, or a group represented by RCO¿2? (R has the same meaning as the above). Examples of the rings A, B, C, D, and E include a cyclopentane ring, a cyclohexane ring, and crosslinked rings. Examples of R include vinyl, isopropenyl, and allyl. |
