Multi-layer surface product e.g. toilet paper, has coinage forming sample, which is raised contrast-moderately from color of thickness at front side or rear side of product, where material of center thickness of product is dyed

摘要

The product has a coinage forming a micro sample (MP), from which a thickness adhesion exists between the thicknesses over coinage knob of the sample by a colored adhesion, so that the corresponding sample appears on the front side or rear side of the product. The sample is raised contrast-moderately from the color of the thickness at the front or rear side of the product. The material of the center thickness of the product is dyed.
