Completely or partially colored interlayer film for laminated glazings, comprises plasticizer-containing polyvinyl acetal, perylene pigments, UV-absorber, and colored and colorless sections

摘要

The completely or partially colored interlayer film comprises plasticizer-containing polyvinyl acetal, perylene pigments, UV-absorber, and colored and colorless sections, where 1-80% of a visible surface is colored and contains a mixture of plasticizer-containing polyvinyl acetal, perylene pigments and UV-absorber and 99-20% of the visible surface is colorless and contains a transparent mixture on the basis of plasticizer-containing polyvinyl acetal without perylene pigments. The interlayer film or the colored sections have a transparency difference (delta D) of 20%. The completely or partially colored interlayer film comprises plasticizer-containing polyvinyl acetal, perylene pigments, UV-absorber, and colored and colorless sections, where 1-80% of a visible surface is colored and contains a mixture of plasticizer-containing polyvinyl acetal, perylene pigments and UV-absorber and 99-20% of the visible surface is colorless and contains a transparent mixture on the basis of plasticizer-containing polyvinyl acetal without perylene pigments. The interlayer film or the colored sections have a transparency difference (delta D) of 20% for near-infrared radiation with 880 nm less than the transparency for sunlight radiation on thermoluminescence with 380-780 nm.
