| abstract |
The present invention relates to a resin composition obtained by adding a compound having a 9,9-bisarylfluorene skeleton represented by the following formula (2) having a polar substituent to a cyclic olefin resin having a functional group. Obtained, and the resin composition has a moderate degree of Abbe number;nIn the formula, ring Z represents an aromatic hydrocarbon ring, R3 and R4 represent a substituent, and group X represents a group -[(OR5)n1-Y1] (wherein substituent Y1 represents a hydroxyl group, a mercapto group, a propylene group oxygen group) a (meth) propylene fluorenyloxy group, R5 represents an alkylene group, n1 represents an integer of 0 or more or a group of -[(CH2)n2-Y2] (wherein the substituent Y2 represents a carboxyl group, an alkoxy group) a carbonyl group, an amine group or a substituted amine group, n2 represents an integer of 0 or more, k represents an integer of 0 to 4, m represents an integer of 0 or more, p represents an integer of 1 or more; and the resin composition has an intermediate The Abbe number of the area (Abbe number of about 28 to 55) is used as an optical lens or the like. |
