<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium that forms an extremely fine recording mark with light of small energy, and easily records or reproduces stable information. <P>SOLUTION: This composition for optical information recording material is expressed by general formula (I-1), includes 0.1-100 mol% of structure unit M1 and 0-99.9 mol% of structure unit A1, and includes (a) base polymer where number average molecular weight is larger than 10,000 and equal to or smaller than 1,000,000, (b) donor acceptor type norbornadienyl derivative, and (c) crosslinking agent by request. In the formula, the structure unit M1 is a structure unit originating in fluorine-containing ethylene-property monomer expressed by general formula (I-2), and the structure unit A1 is a structure unit originating in monomer copolymerizable with fluorine-containing ethylene-property monomer expressed by general formula (I-2). <P>COPYRIGHT: (C)2011,JPO&INPIT |
