| titleOfInvention | Bis-stilbene compounds |
| abstract | The present invention relates to new bis-stilbene compounds of the formula WHEREIN R1 and R2 are identical or different and denote alkyl with 5 to 18 carbon atoms, substituted alkyl with a total of 2 to 20 carbon atoms, or alkenyl with 3 to 4 carbon atoms, X1 and X2 are identical or different and denote hydrogen, alkoxy with 1 to 4 carbon atoms, halogen, alkenyl with 3 to 4 carbon atoms or alkyl with 1 to 4 carbon atoms, Y1 and Y2 are identical or different and denote hydrogen, halogen, alkenyl with 3 to 4 carbon atoms or alkyl with 1 to 4 carbon atoms, a represents hydrogen, halogen, alkoxy with 1 to 4 carbon atoms or alkyl with 1 to 4 carbon atoms, and the parapositions are free of alkoxy groups or R1O- and R2O- groups. The new compounds are useful as optical brighteners. This is a division of application Ser. No. 230,931, filed on Mar. 1, 1972, and now U.S. Pat. No. 3,843,718. |
