Plasticizer-containing films based on polyvinyl acetal containing a UV absorbers of the oxanilide type of formula (1) exhibit high UVA transmission while also exhibiting low UVB transmission, with reduced tendency to yellow.

Plasticizer-containing films based on polyvinyl acetal having selective permeability for UV radiation

The invention relates to a method of producing a solar module by laminating a layer body consisting of a first carrier, to which at least one solar cell unit is applied, and a second carrier by at least one intermediate film based on a plasticizer-containing polyvinyl acetal by guiding the layer body between at least one pair of rollers at a temperature of 50 to 150&#xb0; C.

Method of producing solar modules by the roller laminate process

The invention relates to a film based on plasticizer-containing polyvinyl acetals having improved uniformity of length variations over the width of the film for manufacturing laminated glazing and its use in laminated glazing or solar modules.
