  • Film for composite security disks with self-adhesiveness
    Patent number: 7250217
    Abstract: Plasticized films suitable as an intermediate layer in laminated safety glass and based on partially acetalized polyvinyl alcohols, in particular PVB, have not only the required excellent adhesion to glass but also undesired self-adhesion (susceptibility to blocking). Amounts of from 0.001 to 0.1% by weight of a pentaerythritol ester are proposed for use as an additive which reduces self-adhesion. This additive does not alter the adhesion of the film to glass. The invention is used for producing films for the production of laminated safety glass. The need to cool the films for stacking or wind-up is substantially eliminated.
