| titleOfInvention | Phthalocyanine compound and optical recording medium containing it |
| abstract | A phthalocyanine represented by the formula (1) <IMAGE> (1) wherein each of R1, R2, R3 and R4 is independently an alkyl group substituted by 0 to 5 halogen atoms and having 1 to 20 carbon atoms, an alkenyl group substituted by 0 to 5 halogen atoms and having 2 to 20 carbon atoms or an alkynyl group substituted by 0 to 5 halogen atoms and having 2 to 20 carbon atoms, and at least one of R1, R2, R3 and R4 is substituted by the halogen atom; X is a halogen atom; each of k, l, m and n is independently a value of from 0 to 3; each of o, p, q and r is independently a value of 0, 1 or 2, and all of them are not 0 simultaneously; each sum of k and o, l and p, m and q, and n and r is independently in the range of from 0 to 4; Met is two hydrogen atoms, a divalent metal atom, a trivalent mono-substituted metal atom, a tetravalent di-substituted metal atom or an oxy-metal atom; an optical recording medium formed by adding this phthalocyanine to a recording layer; and a near infra-red absorbing agent comprising the phthalocyanine. The above-mentioned phthalocyanine can be used to provide the optical recording medium having excellent characteristics of reflectance, sensitivity, recording properties, stability to reproduction light, shelf stability and the like. |
