    摘要: The invention provides an optical information recording medium having a recording layer capable of recording information by irradiating the recording layer with a laser beam of 440 nm or less.In the optical information recording medium, the recording layer contains an oxonol dye represented by formula (1), and a counter cation (Yt+) of this dye is a cationic dye having an absorption maximum in a range of longer wavelengths than an absorption maximum of an anionic part of the oxonol dye. In the formula, A, B, C and D each represents an electron-withdrawing group. A and B or C and D may be combined with each other to form a ring. If these are not combined with each other, these are electron-withdrawing groups in which the sum of Hammett's σp values of A and B and the sum of Hammett's σp values of C and D are each greater than 0.6. R represents a substituent group on methine carbon, and m represents an integer of 0 to 1. n represents an integer of 0 to 2m+1. If n is 2 or greater, a plurality of R's may be different from each other, and R and R may be combined together to form a ring. Yt+ represents a t-valent cation, and t represents an integer of 1 to 4.
