Abstract
The present invention is directed to an article with a patterned appearance provided by a visually observable contrast between one or more generally transparent thin film coatings deposited over a substrate. At least one of the deposited coatings exhibits a reflected color and/or contrast and visible differing transmitted color and/or contrast or a plurality of coatings together exhibit different reflected colors and/or contrasts. The coatings are selected from the group of: metals depositable by magnetron sputtering vacuum deposition, chemical vapor deposition, pyrolytic coating, or sol-gel techniques, metal oxide coatings, metal nitride coatings, semi-conductor containing coatings, metal oxynitrides and mixtures thereof. The present invention is also directed to a method of making the articles having a visually observable patterned appearance involving masking and applying the coating or applying the coating and removing a portion of the coating to form the pattern.
