摘要： Provided is an information recording medium and a method for recording information thereon. The information layer of the recording medium comprises a naphthalocyanine chromophore, e.g., a sulfonamidonaphthalocyanine having silicon or germanium as the central hetero atom. Information can thereby be readily recorded via a thermal deformation technique due to the effective absorption by the dye of light in the wavelength range of about 760-850 nm. The naphthalocyanine chromophores exhibit excellent chemical and photolytic stability, their use thereby increasing the useful life of the recording medium.Provided herein are also novel naphthalocyanine chromophore compounds which are useful in optical recording media, and which exhibit exceptional solubility characteristics. Such chromophores are thereby readily applied as a film in the formulation of an information recording medium.

摘要： Provided is an information recording medium, e.g., an optical recording medium, and a method for recording information thereon. The information layer of the recording medium comprises an organo macrocyclic chromophore containing a central hetero atom or two central hydrogen atoms or isotopes of hydrogen, e.g., a naphthalocyanine having silicon as the hetero atom, which chromophore is substituted with at least one substituent conferring film forming properties to the chromophore, e.g., a monomer or oligomeric substituent comprised of acid, amide or ester units. The information layer thereby offers excellent thermomechanical properties and exhibits excellent absorption properties all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in dye/polymer mixtures is also overcome.

摘要： Provided is an optical data storage medium comprising a chromophore/polymer composition information layer, wherein the chromophore is chemically bound or coordinated with the polymer. The chromophore is an organo macrocyclic chromophore containing a constituent metal atom, and preferably a central metal atom, with the chromophore being coordinated to the polymer through the metal atom. As a result, the chromophore/polymer material has excellent film-forming properties so that the medium can be readily and efficiently manufactured. As well, the resulting information layer offers excellent thermomechanical properties and exhibits excellent absorption properties, all in a single component material. By utilizing a single component material, the problem of dye/polymer phase separation frequently encountered in conventional dye/polymer mixtures is also overcome.

摘要： Provide is an optical data storage medium comprising a chromophore/polymer composition information layer, wherein the polymer and chromophore are chemically bound so as to improve chromophore/polymer compatibility. If necessary, the chromophore or the polymer may be modified to improve their interaction. When modification is desired, it is preferred to modify the polymer so as not to disturb the chromophore structure, which is generally selected for its absorption features. The interaction between the chromophore and polymer can be either covalent on non-covalent. The overall result is an information layer having improved chromophore/polymer compatibility.

摘要： A composite permselective membrane comprises an ultrathin semipermeable layer comprising a polybenzimidazole polymer in occluding contact with at least one surface of a microporous polymer support layer. Such membranes provide better combinations of flux and rejection rates in reverse osmosis processes than do conventional semipermeable membranes of polybenzimidazole polymer alone. In an embodiment, a composite permselective membrane is prepared by casting an ultrathin semipermeable layer of the polybenzimidazole polymer on a microporous polymer support layer. The semipermeable layer is preferably subjected to a drying step to evaporate part of the polybenzimidazole polymer solvent, then contacted with a coagulating bath. In some cases, the properties of the composite permselective membrane can be improved by annealing by contacting with an annealing liquid at an elevated temperature, the annealing liquid being selected from the group consisting of aqueous and non-aqueous solutions of liquid organic compounds which are solvents or non-solvents for the polybenzimidazole, and neat liquid organic compounds which are nonsolvents for said polybenzimidazole polymer.
