Abstract

In a composite pane having a film laminate which adhesively connects two rigid panes to one another to form a pane assembly and comprises at least one colored adhesive film and at least one uncolored adhesive film which can be fused on during production of the pane assembly, according to the invention, at least one intermediate layer is provided between the two differently colored fused-on adhesive films and results in a uniform flattening of the mutually facing surfaces of the two adhesive films while being fused on. This results in the finished product being homogeneously colored when being looked through.
