A photosensitized composite material and a material, an element, a device, and the like, which employ the photosensitized composite material, are provided. In the photosensitized composite material, multiphoton absorption compounds are highly sensitized for practical use by utilizing an enhanced plasmon field. The photosensitized composite material has a structure where the multiphoton absorption compounds are linked to the surface of a fine metal particle through linking groups. The fine metal particle generates an enhanced surface plasmon field in resonance with a multiphoton excitation wavelength. The multiphoton absorption compounds have a molecular structure enabling multiphoton absorption. The photosensitized composite material is contained in or used for, for example, a three-dimensional memory material and a three-dimensional recording medium, an optical power limiting material and an optical power limiting element, a photocuring material and a stereolithography system, and a fluorescent material for a multiphoton fluorescence microscope and a multiphoton fluorescence microscope.

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.

Provided is a pharmaceutical composition, including a drug and a collagen, in which the composition is satisfactory in handleability and has sustained-release property. The sustained-release pharmaceutical composition includes: a drug; a collagen; and at least one kind of sugar selected from monosaccharides, disaccharides, trisaccharides, and tetrasaccharides. The inventors of the present invention have found that the in vivo administration of a collagen solution containing a sugar results in the gelation of a collagen. Based on this finding, the inventors have found that a composition containing a drug, a collagen, and a sugar can control the release rate of the drug, and such composition can be used as a sustained-release pharmaceutical composition.
