Abstract

An anodized aluminum foil and a preparation method thereof relate to the technical field of anodized aluminum foil. The anodized aluminum foil includes a base film, a release layer, an imaging layer, a protective layer and an aluminum layer that are stacked in sequence. The imaging layer includes a first resin and a dye, the first resin is an acrylic resin, the protective layer includes a second resin, and the second resin is an acrylate-acrylic copolymer. The protective layer of the anodized aluminum foil of the present application has good adhesion to the aluminum layer and the imaging layer, which improves the problem of poor adhesion between the imaging layer and the aluminum layer.

Description

technical field [0001] The present application relates to the technical field of anodized aluminum foil, and in particular, to an anodized aluminum foil and a preparation method thereof. Background technique [0002] Anodized aluminum foil generally includes a base film, a release layer, an imaging layer and an aluminum layer. The imaging layer generally contains resins and dyes.
