Stamper, Method for Producing the Same, Method for Producing Molded Material, and Prototype Aluminum Mold for Stamper |
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 0.05μm 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.
