Abstract:
Plasticized polyvinyl butyral sheet containing an infrared-absorbing effective amount of at least one quaterrylenetetracarboxylic diimide infrared-absorbing additive dispersed therein of formula I: whereinR and Râ€² are independently C1-C30-alkyl whose carbon chain optionally is interrupted by one or more of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”COâ€” and/or â€”SO2â€” and which optionally is monosubstituted or polysubstituted by cyano, C1-C6-alkoxy or a 5-, 6- or 7-membered heterocyclic radical which is attached via a nitrogen atom and which optionally contains additional heteroatoms and optionally is aromatic; C5-C8-cycloalkyl whose carbon chain may be interrupted by one or more groups selected from the group consisting of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”COâ€” and/or â€”SO2â€” and which may be monosubstituted or polysubstituted by C1-C6-alkyl; or aryl or hetaryl, each of which optionally is monosubstituted or polysubstituted by C1-C18-alkyl, C1-C6-alkoxy, cyano, â€”CONHR2, â€”NHCOR2 and/or aryl- or hetarylazo, each of which optionally is substituted by C1-C10-alkyl, C1-C6-alkoxy or halogen, where R1 is hydrogen or C1-C6-alkyl; and R2 is hydrogen; C1-C18-alkyl; aryl or hetaryl, each of which optionally is substituted by C1-C6-alkyl, C1-C6-alkoxy, halogen or cyano; X is â€ƒwhere R3 is C1-C8-alkyl, whose carbon chain may be interrupted by one or more groups selected from the group consisting of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”COâ€” and/or â€”S02â€” and which may be monosubstituted or polysubstituted by C1-C6-alkoxy or by a 5- to 7-membered heterocyclic radical which is attached via a nitrogen atom and may contain further heteroatoms and be aromatic; or C5-C8-cycloalkyl whose carbon chain may be interrupted by one or more groups selected from the group consisting of â€”Oâ€”, â€”Sâ€”, â€”NR1â€”, â€”COâ€” and/or â€”SO2â€” and which may be monosubstituted or polysubstituted by C1-C6-alkyl; and p is from 1-16.
