摘要：Resinous polymer sheet materials having selective, decorative effects

comprising: a first layer of a resinous polymer composition; a pattern or design printedon and adhered to the surface of the first layer of resinous polymer composition andhaving a relatively dark colored printed portions and relatively light colored printedportions; and a second layer of a resinous polymer composition applied on and adheredto 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 about1.3 to about 1.7 and having included or embedded substantially uniformly therein a layerof relatively small, flat, decorative chips or flakes comprising a very thin layer oftranslucent or transparent platelets provided with a coating having a refractive index ofat 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, suchthat light wave interference and color absorptive effects are created in light wavesstriking and reflecting from the second layer of resinous polymer composition, wherebythose decorative chips or flakes located over the relatively dark colored printed portionsare discernible from eye-level or a distance of about five feet, whereas those decorative

chips or flakes located over the relatively light colored printed portions are indiscerniblefrom eye-level or a distance of about five feet. Methods of making such resinous polymersheet materials having such selective, decorative effects are also included.
