Abstract
Abstract A light-transmitting plastic resin sheet capable of exhibiting intense multicolor effects is provided. The sheet has positioned therein individual layers of at least two optically colored nacreous pigments of different optical color. The pigment crystals within an individual layer are oriented in parallel spaced relationship with respect to each other. The individual layers are positioned at an angle to each other so that the color transmitted by one of the layers intensifies the purity of the color reflected by another of the layers.
