description The invention relates to a reflective composite material (V) with a substrate (1) consisting of aluminum, with an intermediate layer (2) of anodic oxidized substrate material located on one side (A) of the substrate (1), and with an optically active multi-layer system (3) applied above the intermediate layer (2), wherein the multi-layer system consists of at least three layers, and wherein the upper layers (4, 5) are dielectric and/or oxidic layers, and the bottom layer (6) is a metallic layer consisting of silver which forms a reflective layer (6). To increase the ageing resistance the invention proposes that a diffusion-inhibiting barrier layer (8) is disposed above the intermediate layer (2) and below the reflective layer (6), wherein the reflective layer (6) is bonded to the barrier layer (8) by an adhesion-promoting layer (9).
