  • Publication number: 20210010203
    Abstract: The invention relates to a method for producing a synthetic resin surface or lacquered surface with a variable color, having the steps of providing a support layer with a lower face and an upper face, impregnating the support layer with a liquid impregnant without using a pickling additive and at least drying the impregnated support layer. The aim of the invention is to provide a decorative surface, the coloring of which by the end consumer can be modified in a particularly simple manner and which is particularly inexpensive and resistant. This is achieved in that a layer of coating agent is deposited on the upper face of the support layer and is dried, and the support layer is then connected to a material, wherein the layer is cured in order to form an open-pore layer which is at least as transparent as possible upon drying and/or connecting to the upper face.
