Abstract
We study the critical Casimir force per unit area which determines the film thickness of critical binary liquid wetting films for the specific case of opposite boundary conditions within the film. A universal scaling function is derived in the one-phase region. At criticality this scaling function r educes to a universal amplitude with value Delta(+,-) similar to 0.0053.
