Abstract
A plasticizer-containing film of polyvinyl acetal having a softening temperature Tg of less than 74° C. contains at least one cyclohexane dicarboxylic acid ester as a plasticizer. The plasticizer-containing films have a low tendency for sweating of the plasticizer, and are useful in producing laminate safety glasses and photovoltaic modules.
