摘要： Disclosed herein are a stamper which has anodized alumina formed on the surface thereof and which will not cause macroscopic unevenness or color unevenness on the transcribed surface; a method for producing the same; and a method for producing a molded material without macroscopic unevenness or color unevenness on the transcribed surface thereof by using such a stamper. The stamper includes alumina which has a microasperity structure and which is formed by anodization on the surface of a prototype aluminum mold having an aluminum purity of 99.5% or more, an average crystal-grain diameter of 1 mm or less, and an arithmetic mean surface roughness Ra of 0.05 µm or less. The use of this stamper enables the production of a molded material which does not have macroscopic unevenness or color unevenness on the transcribed surface thereof and which is suitable for use as an antireflection article and the like.

摘要： A method of production of an aluminum alloy inhibiting oxidation loss of the alloy melt without the use of Be which is liable to affect the human health. When preparing an aluminum alloy melt containing Mg, the method adds to the alloy, Ca, Sr, and/or Ba in a composition ratio within a range enclosed by lines connecting four points illustrated in FIG. 1 of a point A (Ca: 18 at%, Sr: 0 at%, and Ba: 82 at%), point B (Ca: 14 at%, Sr: 34 at%, and Ba: 52 at%), point C (Ca: 33.8 at%, Sr: 66.2 at%, and Ba: 0 at%), point D (Ca: 100 at%, Sr: 0 at%, and Ba: 0 at%) and excluding point D so as to adjust the Ca, Sr, and Ba components in the melt to include Ca: 0.001 to 0.5 mass% and one or both of Sr: 0.01 to 2.8 mass% and Ba: 0.01 to 7.83 mass%.

摘要： The present invention relates to an aluminum die base material for a stamper having a component composition that contains 0. 5% by weight to 3.0% by weight of Mg, the total amount of elements other than Mg, including unavoidable impurities, is 500 ppm or less, and the remainder is composed of Al, and a forged structure in which the average crystal grain size is 1000 µ m or less and the surface area ratio of second phase particles is 0.10% or less. According to the present application, a stamper can be provided in which, together with the crystal grain size of the aluminum being refined, the formation of second phase particles is inhibited, surface irregularities attributable to mirrored surface polishing are reduced, and a uniform relief pattern is formed by anodic oxidation treatment.
