An aluminum alloy brazing sheet for a heat exchanger includes a three-layer material in which a brazing material layer, an intermediate layer, and a core material are cladded and stacked, the intermediate layer is formed of an aluminum alloy which can include Mn, Si, Fe, and Cu, with the balance being Al and inevitable impurities, the core material is formed of an aluminum alloy which can include Si, Fe, Cu, and Mn, with the balance being Al and inevitable impurities, and the brazing material layer is formed of an aluminum alloy including Si, with the balance being Al and inevitable impurities.

Aluminum alloy brazing sheet for heat exchanger

The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer, serving as a printing surface, on a printing substrate on which gravure printing is to be performed, and the coating material is characterized by including a vinyl chloride-vinyl acetate-unsaturated fatty acid copolymer that includes 80 to 90% by mass of a component of vinyl chloride, 9.2 to 19.5% by mass of a component of vinyl acetate, and 0.1 to 0.8% by mass of a component of an unsaturated fatty acid.

Coating material, printing member for dot printing, and PTP packaging body

An aluminum alloy brazing sheet includes a four-layer material containing an intermediate layer formed of an aluminum alloy including Mn of from 0.2 to less than 0.35 mass %, Si of 0.6 mass % or less, Fe of 0.7 mass % or less, and Cu of 0.1 mass % or less, with the balance being Al and inevitable impurities, a core material formed of an aluminum alloy including Si of 1.2 mass % or less, Fe of 1.0 mass % or less, Cu of from 0.3 to 1.0 mass %, and Mn of from 0.5 to 2.0 mass %, with the balance being Al and inevitable impurities, and each of an air-side brazing material layer and an internal brazing material layer is formed of an aluminum alloy including Si of from 4 to 13 mass %, with the balance being Al and inevitable impurities.

The present invention provides a coating material that can improve gravure printing characteristics of the printing surface of a printing substrate to favorably transfer an ink fed in the cell of a gravure printing roll to the printing surface of the printing substrate, thereby achieving the beautiful gravure printing. The coating material of the present invention is a coating material for forming a surface layer serving as a printing surface on a printing substrate to which gravure printing is to be applied, and the coating material is characterized by including a pigment including an inorganic particulate and a skin layer that is formed on a surface of the inorganic particulate and includes an organic compound.

A gravure printing roll that enables printing of fine dots with a size close to that of cells and enables printing on a print subject, such as a printing substrate, without changing the appearance of the print subject. The gravure printing roll includes: a gravure printing roll body; and cells formed in a peripheral surface of the gravure printing roll body. Each of the cells has an opening with a ratio between a dimension in a circumferential direction of the gravure printing roll body and a dimension in an axial center direction of the gravure printing roll body (dimension in the circumferential direction/dimension in the axial center direction) being 1.15 to 7, and have an opening area of 3900 &#x3bc;mor smaller.
