The invention relates to a method for producing a composite material, for which a carrier layer (2) is connected to an upper layer (1) of polyurethane or plasticized PVC and the carrier layer (2) comprises a textile material, for example a woven or knitted fabric or a microfibre nonwoven, or a leather, in particular a split cowhide leather, and the upper layer (1) comprises a number of polyurethane layers or plasticized PVC layers (1', 1'') connected to one another. According to the invention, it is provided - that in the composite of upper layer (1) and carrier layer (2) channel-shaped clearances (6) for water vapour and/or air to pass through are formed from the surface of the upper layer (1) by removal of material with a laser in such a way - that at least some of the clearances (6) penetrate the material of the upper layer (1) and/or end before entering the region of the volume of the carrier layer (2) that is free from the material of the upper layer (1).
