Abstract:
The invention relates to film laminates, formed from at least three layers A, B and C, each layer containing at least one plasticizer and at least one polyvinyl acetal, wherein, at least one of the layers A, B or C contains at least one polyvinyl (iso)acetal having a mean degree of polymerization of less than 3000, 10 to 25% by weight of polyvinyl alcohol groups and a proportion 50 to 80% by weight of polyvinyl (iso)acetal groups, and wherein layer B has a plasticizer content of less than 32% by weight. The film laminates can be used for the production of glass/film laminate/glass composites for motor vehicles, aircraft, ships, architectural glazings, façade components, or for the production of photovoltaic modules.
