Abstract
An asymmetric pigment including a first Fabry-Perot structure; and a second Fabry-Perot structure; wherein the first Fabry-Perot structure and the second Fabry-Perot structure have a similar hue angle within +/−45 degrees is disclosed. Other asymmetric pigments are also disclosed as well as methods of making the disclosed pigments.
Claims18
An asymmetric pigment, comprising:
- a first Fabry-Perot structure on a first side of the asymmetric pigment, the first Fabry-Perot structure including a first dielectric layer;
- and
- a second Fabry-Perot structure on a second side of the asymmetric pigment, the second Fabry-Perot structure including a second dielectric layer;
- wherein the average thickness of the first Fabry-Perot structure and the second Fabry-Perot structure is a ratio of 1:2.5 to 1:3.5, and
- wherein the second side is opposite the first side.

An asymmetric pigment, comprising:
- a first Fabry-Perot structure on a first side of the asymmetric pigment, the first Fabry-Perot structure including a first dielectric layer;
- and
- a second Fabry-Perot structure on a second side of the asymmetric pigment, the second Fabry-Perot structure including a second dielectric layer;
- wherein the first Fabry-Perot structure has an optical thickness different from an optical thickness of the second Fabry-Perot structure,
- wherein the first Fabry-Perot structure includes a 2 quarter wave optical thickness ranging from about 200 nm to about 400 nm or a 4 quarter wave optical thickness ranging from about 400 nm to about 600 nm;
- wherein the second Fabry-Perot structure includes a 4 quarter wave optical thickness ranging from about 400 nm to about 600 nm or a 6 quarter wave optical thickness ranging from about 600 nm to about 800 nm;
- and wherein if the first Fabry-Perot structure includes a 4 quarter wave optical thickness then the second Fabry-Perot structure includes a 6 quarter wave optical thickness, and
- wherein the second side is opposite the first side.
