The method consists in continuously unwinding the metal strip (1) on at least a back-up roll (3); forming, on a roll (20) by forced flow, a layer of said crosslinkable polymer in melted state; forming, from said layer (30), said crosslinkable polymer film (31); and transferring entirely in thickness said film onto the metal strip (1) and, between the zone forming the layer (30) on the roll (20) and the zone applying the film (31) on the metal strip, in thermally conditioning the crosslinkable polymer to reduce its viscosity. The invention also concerns a coating device for implementing said method.

  • Patent number: 6548162
    Abstract: Sanitary wares having a controlled surface are disclosed which are less likely to be stained or soiled and/or possess excellent gloss. The first sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a center line average roughness Ra of less than 0.07 &mgr;m. This sanitary ware is advantageous in that stains or soils are much less likely to be adhered to the surface thereof and, even when adhered to the surface thereof, can be removed by a weak water stream. The second sanitary ware comprises a sanitary ware body and a surface glaze layer provided on the sanitary ware body, wherein the surface glaze layer has a kurtosis Rku of less than 2.70. This sanitary ware advantageously possesses excellent surface gloss.

  • Patent number: 6482471
    Abstract: In an image-forming substrate, a layer of microcapsules is coated over a sheet of paper, and contains at least one type of microcapsule filled with a solid ink. A shell element of each microcapsule is constituted so as to be squashed and broken under a predetermined pressure when the solid ink of each microcapsule is thermally melted at a predetermined temperature to discharge thermally-molten ink from the squashed and broken microcapsule.

  • Patent number: 6479105
    Abstract: The present invention provides a composition comprising a low-molecular weight, amorphous polyalphaolefin layer and a water-sensitive substrate layer. Preferably, the polyalphaolefin comprises either a propylene-ethylene copolymer or an ethylene-butene copolymer. Polyalphaolefin coated water-dispersible films of the present invention may be advantageously employed in the preparation of a wide variety of products designed to be contacted with aqueous fluids. Although the coated water-dispersible film of the present invention is particularly suited for personal care products, the coated water-dispersible film of the present invention may be advantageously employed in the preparation of a wide variety of consumer products other than personal care products. When the entire product is disposed of in water, the water-sensitive layer is wetted and weakens.

  • Patent number: 6472014
    Abstract: A method is provided for texturing the surface of a substrate to enhance the adhesion and to reduce the stress concentration of coatings applied to the substrate. In one embodiment, a first layer of first spheres is applied to the substrate to provide a textured surface onto which is deposited a second layer of larger second spheres. The layered substrate is then reflowed to melt the first layer of first spheres so that the second layer of second spheres is embedded in the formed first reflowed layer and which second layer of second spheres protrudes above the top of the reflowed layer and forms a textured surface corresponding to the shape of abutted and/overlapping second spheres. In another embodiment, the first layer of first spheres is reflowed and then a second layer of second spheres deposited thereon. The first layer is then again reflowed embedding the second spheres therein.

  • Patent number: 6468584
    Abstract: A method for manufacturing a conductive thin film patterned substrate which is capable of being practiced at a reduced cost without causing environmental pollution while eliminating any troublesome after-treatment. An insulating substrate made of glass or the like is formed thereon with an InSnO, SnSbO, ZnAlO or Al thin film. Then, a phosphate low-softening glass paste layer is formed on the thin film. A portion of the thin film contiguous to an insulating layer made of the low-softening glass paste melts into a glass region to form an insulating layer region, so that a conductive thin film region may be patterned as electrodes.
