Colored articles and compositions and methods for their fabrication

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