Reflecting composite material with an aluminum support and with a silver reflection layer

摘要

The invention relates to a reflective composite material (V) comprising a support (1) made of aluminum, having an intermediate layer (2) of anodically oxidized support material on one side (A) on the support (1) and with an intermediate layer (2 ), which consists of at least three layers, wherein the upper layers (4, 5) are dielectric and / or oxidic layers, and the lowermost layer (6) is a metallic layer consisting of silver, which forms a reflection layer (6). To increase the aging resistance, it is proposed that a diffusion-inhibiting barrier layer (8) is arranged above the intermediate layer (2) and below the reflection layer (6), wherein the reflection layer (6) is bonded to the barrier layer (8) via an adhesion promoter layer (9) ,
