ABSTRACT:
Reduction in the adhesion to glass of thermoplastic, plasticized polyvinylbutyral molding compositions, in particular sheeting, by the addition of a metal salt and/or metal chelate of an enolizable .beta.-diketone, or mixtures of these compounds, as an non-stick agent, preferably in amounts of 0.003 to 0.3% by weight, relative to the plasticized polyvinylbutyral. It is preferable to employ the non-stick agent in the form of a solution in the plasticizer. The use of the sheeting having an adhesion to glass reduced in accordance with the invention as a laminating layer for the production of glass laminates.
