Abstract
Resinous polymer sheet materials having selective, decorative effects comprising: a first layer of a resinous polymer composition; a pattern or design printed on and adhered to the surface of the first layer of resinous polymer composition and having a relatively dark colored printed portions and relatively light colored printed portions; and a second layer of a resinous polymer composition applied on and adhered to the printed pattern or design and to the first layer of resinous polymer composition, the second layer of resinous polymer composition having a refractive index of from about 1.3 to about 1.7 and having included or embedded substantially uniformly therein a layer of relatively small, flat, decorative chips or flakes comprising a very thin layer of translucent or transparent platelets provided with a coating having a refractive index of at least about 1.8 and at least 0.2 greater than the refractive index of any surrounding, contacting material, and a thickness of from about 0.05 micron to about 2 microns, such that light wave interference and color absorptive effects are created in light waves striking and reflecting from the second layer of resinous polymer composition…
