Definitions
- the compression method according to the invention is preferably for anodized Aluminum or anodized aluminum alloys used. However, it can also on the anodizing layers of other anodizable metals such as For example, use titanium and magnesium or their alloys. It can be used both for undyed anodizing layers and for those those using conventional methods such as integral staining, one Adsorptive staining using organic dyes, a reactive one Coloring with the formation of inorganic color pigments, an electrochemical Coloring using metal salts, especially tin salts, or an interference stain. With adsorptively colored Anodizing layers, the method according to the invention has the further advantage that due to the shorter compression time that with conventional Hot compression possible bleeding of the dye can be reduced.
