Abstract
Multilayer stacks that can be used as decorative microsphere articles. The decorative microsphere articles can be a durable and aesthetically pleasing substitute for anodized aluminum and other matte metallic surfaces. The decorative microsphere articles are durable and can have a bright diffused appearance of any desired color, for example white, gold, silver, red, or other colors, while being capable of being manufactured using a roll-to-roll process. The decorative microsphere articles can also provide novel optical effects than can change at different viewing angles, including, for example, changing color with view angle, changing sharpness or clarity of an image or icon with view angle, and the like, that may allow customers to differentiate their products.
