Abstract:
The present invention provides a gas separation composite which has high heat resistance and mechanical strength, prevents a support layer from being deformed or damaged by heat during formation of a gas separation membrane and heat during a gas separation operation, and properly supports a gas separation layer to obtain high gas permeability and gas separation properties; and a method of producing the gas separation composite. The gas separation composite includes a metal support having a plurality of through holes in the thickness direction and a gas separation layer laminated on the surface of the metal support. The thickness of the gas separation layer is in a range of 0.1 to 5 µm, the average opening diameter of the through holes of the metal support is in a range of 0.1 to 30 µm, and the opening ratio thereof is in a range of 0.05% to 10%.
Abstract:
A lithographic printing plate precursor is disclosed, comprising a metal support having formed thereon an anodic oxide film, and an image-forming layer containing a light-to-heat converting agent, or a light-sensitive layer capable of image-forming with infrared laser exposure provided in this order from the support.
Abstract:
Objects of the present invention are to provide a positive working presensitized plate of a thermal type, which has damage resistance, and which is handled easily in conventional operation, high in sensitivity and excellent in press life when used as a lithographic printing plate, and to provide a support for a lithographic printing plate, which is suitably used for the same. The objects have been achieved by a support for a lithographic printing plate obtained by performing graining treatment, alkali etching treatment and anodizing treatment on an aluminum plate, wherein a ratio of a real area of a surface thereof to an apparent area of the surface set larger by 1.3 to 1.8 times, comprising a pit having an average diameter of 0.3 to 1.0 mu m and a micro grained structure inside on the surface, wherein a ratio of an apparent area of the pits to the apparent area of the surface is 90 % or more; and a presensitized plate comprising the support for a lithographic printing plate and a photosensitive layer that can become alkali-soluble by heating provided on the support.
Abstract:
Disclosed is a support for a lithographic printing plate, wherein an adhering amount of a rare-earth element atom to a surface thereof is 0.1 to 20 mg/mg , and a presensitized plate provided with an image recording layer on the support for a lithographic printing plate. The presensitized plate achieving both high scum resistance and long press life can be realized, which is the same in the case the image recording layer containing an infrared absorbent, where scum would easily occur, is provided onto the support.
