Abstract
Various methods and apparatus relating to a multi-level layer are disclosed.
Claims25
A method comprising:
- providing a first layer of material, wherein the first layer is transparent;
- selectively treating portions of the first layer such that differently treated portions exhibit different degrees of material volatilization from the first layer to form different levels, wherein portions of the first layer include at least 20 percent by solids of bisphenol A diglycidyl ether (BADGE) and wherein other portions of the first layer include less than or equal to about 5 percent by solids of bisphenol A diglycidyl ether (BADGE);
- providing a second layer of a partially transparent reflective material adjacent the first layer;
- and
- providing a third layer of a partially transparent reflective material or a reflective material opposite the second layer of a partially transparent reflective material and spaced from the second layer of a partially transparent reflective material.

- selectively treating portions of the first layer such that differently treated portions exhibit different degrees of material volatization from the first layer to form different levels;
- providing a second layer of a partially transparent reflective material on a first side of the first layer;
- and
- providing a third layer of a partially transparent reflective material or a reflective material opposite the second layer of a partially transparent reflective material on a second side of the first layer.
