Abstract

A method for producing a color-changeable synthetic resin surface or lacquered surface includes providing a backing layer with a bottom side and a top side, fully impregnating the backing layer with a liquid impregnant without a stain additive and at least drying the impregnated backing layer. In order to provide a decorative surface with coloring which can be modified by the end consumer in a simple, inexpensive and resistant manner, a layer of coating agent is applied to the top side of the backing layer and is dried, and the backing layer is then bonded to a material, wherein the one layer is cured in order to form an open-pore layer which is at least as transparent as possible upon drying and/or bonding on the top side.
