Abstract
The invention concerns a functional laminate and a method for manufacturing said functional laminate, the method comprising the following steps:--providing a substrate sheet (1);--inserting at least one functional component (2) into the substrate sheet (1);--wearing out the substrate sheet (1) and/or at least one layer laminated to the substrate sheet (1) in an area adjacent to the functional component (2) resulting in at least one recess (5) with a small width in proportion to dimensions of the functional component (2) before at least one lamination step;--carrying out at least one lamination step, wherein the substrate sheet (1) is laminated with at least one additional layer by heat and/or pressure and/or gluing in such a manner that the width of the at least one recess (5) is considerably reduced or the at least one recess (5) is barely shut at least by surrounding material after lamination by virtue of shrinking of the substrate sheet (1) and/or the at least one additional layer.
