    • Disclosed are a phthalocyanine near infrared absorbing material having a phthalocyanine skeleton whose benzene rings contain a silyl group as a bulky substituent and an optical information recording medium containing the material. The phthalocyanine near infrared absorbing material has excellent association-preventing property and light resistance and exhibits a high index of refraction at a wave length of 770-830 nm and high stability, an optical information recording medium (CD-R recording medium) containing the phthalocyanine has high reflectance, excellent storage stability and excellent reproduction stability. The recording medium also shows strong light absorptivity and light reflectivity in a wave length of 630-700 nm and, thus, is applicable for the pick up with a semiconductor laser of 630-700 nm, permitting such high density recording as to provide 1.6-1.7 times as high recording density as that attained by currently employed recording media which are adapted to 780-810 nm.
