<p>The optically thermal writable materials (1,2), like paper, cardboard pigment particle spraying or die casting plastic units, are coated with multiple thin layers, where the material is uniform. A reflective layer (3) is provided, which partially reflects electromagnetic waves uniformly or at layer border. A transparent layer (4) is placed above or below the reflective layer. Another layer made of metallic or strong chromophore particle or nano-particles (5) or their chemical precursor or a metallic thin film, is placed on the transparent layer. Independent claims are included for the following: (1) a method for manufacturing optically thermal coated materials (2) a method for colorless coating of materials.</p> |
