Title:
METHOD FOR FORMING ANODIZED LAYER, METHOD FOR PRODUCING MOLD, METHOD FOR PRODUCING ANTIREFLECTIVE FILM, AND MOLD AND ANTIREFLECTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2011/027746
Kind Code:
A1
Abstract:
Disclosed is a method for forming an anodized layer, comprising: a step (a) for preparing an aluminum substrate (10) having a surface (18s) formed of aluminum; a step (b) for anodizing the surface (18s) to form a barrier-type alumina layer (12); and a step (c) for further anodizing the surface (18s), after the step (b), to form a porous alumina layer (14) having a plurality of microconcavities (14p). Thus, a method, whereby a porous alumina layer having desired intervals among pores can be formed by using an aluminum substrate having a surface formed of aluminum regardless of the surface form, is provided.
