ABSTRACT:
The uppermost, porous layer consists of a filler material free plastic material, of which the particles are melted together at their mutual contact areas. This forms capillaries, through which the coloring material is transported downwards. A receiving layer for the respective color material, which penetrates thereinto capillarily by diffusion, is located under the porous upper layer. These two layers lie on a supporting layer.
Because during a printing the coloring material is transported capillarily through the uppermost layer to the middle layer, an immediate drying at the surface of the record carrier occurs. A lateral spreading, i.e. running of the coloring material, does not occur. Thus no smudged areas are formed and the pictures are of an excellent brilliancy.
