20120148875 | LUBRICANT FOR MAGNETIC DISC, MAGNETIC DISC AND METHOD OF PRODUCING THE SAME - A magnetic disk with which further reduction of magnetic spacing can be realized and which has high reliability under such circumstances of a lower floating amount of a magnetic head involved in the recent rapid increase in recording density and of extremely severe environmental resistance involved in diversification in use applications is provided. | 06-14-2012 |
20120225217 | METHOD OF PRODUCING A MAGNETIC RECORDING DISC - A method of manufacturing a magnetic disk in which at least a magnetic layer, a carbon protective layer, and a lubrication layer are sequentially formed on a substrate is provided. The method comprises forming a film of a lubricant composition on the protective layer, the lubricant comprising a lubricant compound having a perfluoropolyether main chain in the molecular structure and an aromatic group or a phosphazene ring. The method further comprises forming the lubrication layer, and subjecting the magnetic disk to ultraviolet irradiation under a nitrogen gas or an inert gas atmosphere having an oxygen concentration of 5 volume % or less by adjusting an atmospheric temperature to a range of 50 to 180° C. | 09-06-2012 |
20120276417 | LUBRICANT FOR MAGNETIC DISK AND MAGNETIC DISK - A lubricant for a magnetic disk that is excellent in heat resistance and is suitably used in a magnetic disk to be mounted on a magnetic recording device of a thermally assisted magnetic recording system and a magnetic disk provided with a lubricant layer containing this lubricant. The lubricant for a magnetic disk contains a compound where perfluoropolyether groups each having a perfluoropolyether main chain in its structure and a phosphazene ring at an end are linked to each other through a linking group. The linking group is an aliphatic group or a phosphazene ring. In a magnetic disk having at least a magnetic recording layer, a protective layer, and a lubricant layer on a substrate, the lubricant layer contains the lubricant for a magnetic disk. | 11-01-2012 |
20130194664 | POLARIZING LENS - An aspect of the present invention relates to a polarizing lens, which comprises a polarizing layer comprising a dichroic dye and a functional film in this order on a lens substrate, and further comprises a waterborne resin layer between the polarizing layer and the functional film as a layer adjacent to both the polarizing layer and functional film, wherein the waterborne resin layer is greater than 0.50 μm in thickness and has been formed by coating and drying a waterborne resin composition comprising a polyether polyurethane resin and a water-based solvent. | 08-01-2013 |
20130196077 | METHOD OF MANUFACTURING POLARIZING LENS - An aspect of the present invention relates to a method of manufacturing a polarizing lens, which comprises forming a polarizing layer by orienting and depositing a dichroic dye on a lens substrate; conducting an amino silane treatment by impregnating the polarizing layer with a solution of a silane coupling agent comprising an amino group; coating a waterborne resin composition comprising a polyether polyurethane resin and a water-based solvent on the polarizing layer following the amino silane treatment and then drying the waterborne resin composition to form a primer layer; and forming a cured coating by coating a curable composition on the primer layer that has been formed and then conducting a curing treatment. | 08-01-2013 |
