A process for making a card includes the steps of forming a core layer having a first surface and a second surface, disposing an uncured decorative ceramic layer of ceramic particles disposed in a resin binder over the first surface of the core layer, such as by spray coating, and curing the uncured decorative ceramic layer to form a cured decorative ceramic layer. Card products of the process may have a core layer of metal, ceramic, or a combination thereof that form a bulk of the card.

A method for creating colorful patterns on a metal surface by using colorless ink is revealed. First carry out a first anodizing process on a metal substrate to form a first anodic oxide layer on a surface of the metal substrate. Then coat a layer of colorless ink on the first anodic oxide layer on the surface of the metal substrate to form a colorless ink pattern mask. Later perform a second anodizing process to form a second anodic oxide layer on a part of the metal substrate without being covered with the colorless ink pattern mask. Next remove the colorless ink pattern mask and coat a metal film over the first anodic oxide layer and the second anodic oxide layer to get a colorful pattern on the metal substrate.

Disclosed herein are methods specifically tailored for facilitating the mitigation of cosmetic impressions associated with fingerprint impressions on surface(s) of articles of manufacture made from anodized substrates. To this end, such methods provide for removal of fingerprints by enzymatically functionalizing the surface(s) of the article of manufacture (e.g., a cosmetic coating thereof) to generate an enzymatically active surface and activating such enzymatically functionalized surface(s) to promote such fingerprint removal. Thus methods and articles of manufacture made in accordance with such methods provide improved end-use utility and functionality of many products for consumer electronic applications, automotive applications, building materials applications, and the like.
