#CMT# #/CMT# 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%. #CMT# : #/CMT# 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. #CMT#USE : #/CMT# Completely or partially colored interlayer film for laminated glazings, and for windshields in motor vehicles or airplanes (all claimed). #CMT#ADVANTAGE : #/CMT# The completely or partially colored interlayer film has improved near-infrared transparency, high UV-stability and low infrared-/near-infrared-absorption thus allowing an automatic control of the windshield wiper function. #CMT#ORGANIC CHEMISTRY : #/CMT# Preferred Components: The perylene pigments are N,N'-dimethyl perylene dicarboxylic acid diimide or perylenetetracarboxylic acid anhydride. The polyvinyl acetal is uncross-linked and cross-linked polyvinyl butyral or polymer obtained by partially acetalizing hydrolyzed vinyl acetate-ethylene copolymer. The plasticizer is a compound consisting of di-2-ethylhexyl-sebacate, di-2-ethylhexyl-adipate, di-2-ethylhexyl phthalate, diethylhexyl-adipate, dibutylsebacate, di-(2-butoxyethyl)-sebacate, triethylene glycol bis(2-ethylhexanoate), triethylene glycol bis-n-heptanoate (3G7), tetraethylene glycol bis(n-heptanoate) (4G7), di(2-butoxyethyl) adipate and di-(butoxy-ethoxy-ethyl)adipate. The UV-absorber is amine, sterically hindered amines, benzotriazole derivative or organophosphite. |
