ABSTRACT:
A process for coloring high molecular organic material, which comprises the use of isoindolines of formula I ##STR1## wherein A is a group of formula ##STR2## wherein R is a group selected from --CONHR.sub.1, --COOR.sub.2 and ##STR3## and R.sub.1 is hydrogen, C hd 1-C.sub.4 alkyl, phenyl or phenyl which is substituted by one or more identical or different members of the group consisting of halogen, C.sub.1 -C.sub.4 alkyl, C.sub.1 -C.sub.4 alkoxy, --COR.sub.3, --NHCOR.sub.4 or ##STR4## in which formulae R.sub.3 is C.sub.1 -C.sub.4 alkoxy, --NH.sub.2 or --NHR.sub.4,
R.sub.4 is C.sub.1 -C.sub.4 alkyl and
R.sub.5 is hydrogen, halogen or C.sub.1 -C.sub.4 alkyl, and
R.sub.2 is C.sub.1 -C.sub.4 alkyl and Q is --NH or --S--;
or A is a group of formula ##STR5## wherein V is NH or O, X.sub.1 and X.sub.3 are each independently of the other halogen, C.sub.1 -C.sub.4 alkoxy, C.sub.1 -C.sub.4 alkylmercapto, or phenoxy or phenylmercapto, each unsubstituted or substituted by halogen, C hd 1-C.sub.4 alkyl or C.sub.1 -C.sub.4 alkoxy, and X.sub.2 is halogen.
The strong colorations obtained by this process are distinguished in particular by good fastness to migration, heat, light and weathering.
