Disclosed is a trimethine dimer compound represented by the following general formula (I) and optical recording medium containing such a compound in a recording layer.
(I)(In the formula, symbols are as in the description. When both X
a2
and X
b2
are imino groups, one of X
a1
, X
b1
, X
a3
and X
b3
is necessarily a 1-alkyl-1-benzylmethylene group which may have a substituent, a 1,1-dibenzylmethylene group which may have a substituent or a cycloalkane-
1,1
-diyl group having 3 to 6 carbon atoms which may have a substituent.)
