Abstract
This invention provides improved methods and compositions for achieving material coloration using particle scattering. These coloration effects can be designed to be either highly stable or dependent upon the switching effects of either temperature, integrated thermal exposure, moisture absorption, or exposure to actinic radiation. Articles employing materials with these coloration effects are described. Composition comprise a solid, light-transmitting matrix component having a non-liquid particle scattering colorant dispersed. Articles are produced wherein another solid second matrix component has an electronic transition colorant dispersed therein and the first and second compositions are disposed on one another and optionally interpenetrate each other. Colored articles are produced in the form of fibers, films and molded articles.
