| titleOfInvention | Triazinyl-benzofluorans |
| abstract | Fluorans useful as color precursors, particularly in the art of carbonless duplicating are normally colorless and are represented by the structural formula ##STR1## wherein R represents non-tertiary alkyl of one to four carbon atoms; R 1 represents hydrogen or non-tertiary alkyl of one to four carbon atoms; R 2 and R 3 represent chlorine or one of the groups n --NR 4 --(lower-alkylene)--N(R 5 )(R 6 ) or n --NR 4 --(lower-alkylene)--N + (R 7 )(R 8 )(R 9 )An - n In which R 4 , R 5 and R 6 represent hydrogen or non-tertiary alkyl of one to four carbon atoms; R 7 and R 8 represent non-tertiary alkyl of one to four carbon atoms; R 9 represents non-tertiary alkyl of one to four carbon atoms, benzyl or benzyl substituted in the benzene ring by one or two of halo or alkyl of one to three carbon atoms; and An represents an anion. |
