| abstract |
The present invention relates to a resin composition obtained by adding a compound which has polar substituents, is represented by the following formula (2), and includes a 9,9-bisarylfluorene skeleton, to a cycloolefin-based resin having a functional group, the resin composition having a moderate Abbe number.n[In the formula, ring Z represents an arene ring; R 3 and R 4 each represent a substituent; group X represents -[(OR 5 ) n1 -Y 1 ] (wherein substituent Y 1 represents a hydroxyl, mercapto, glycidyloxy, or (meth)acryloyloxy group, R 5 represents an alkylene group, and n1 is 0 or an integer of 1 or larger) or -[(CH 2 ) n2 -Y 2 ] (wherein substituent Y 2 represents a carboxyl, alkoxycarbonyl, amino, or substituted amino group and n2 is 0 or an integer of 1 or larger); k is an integer of 0-4; m is 0 or an integer of 1 or larger; and p is an integer of 1 or larger.]nThis resin composition has an Abbe number in an intermediate range (Abbe number of about 28-55) and is useful as an optical lens, etc. |
