ABSTRACT:
This invention relates to a process for coloring polyurethane resins during the production of same with reactive colorants derived from novel polyalkoxytrifluoroaniline intermediates. These colorants impart increased brightness in shade for both aromatic and heteroaromatic derivatives and increased resistance to stannous octanoate catalyst over conventional polymeric colorants derived for heteroaromatic compounds. These novel colorants have the structure: ##STR1## wherein R.sub.1 is selected from H, a lower alkyl group containing from 1 to about 10 carbon atoms, CH.sub.2 Cl, CH.sub.2 OH, phenyl or ##STR2## where R.sub.6 is H or a lower alkyl group containing from 1 to about 9 carbon atoms; R.sub.2 is selected from OH, NH.sub.2 or SH; R.sub.3 is selected from a lower alkyl group containing from 1 to about 9 carbon atoms, cyanoalkyl, acetoxyalkyl or ##STR3## where R.sub.1 and R.sub.2 are as given above; R.sub.4 is H, CF.sub.3, a lower alkyl group containing from 1 to about 9 carbon atoms, Cl or Br and n is 0 or an integer form 1 to about 125. R.sub.5 is an aromatic or heteroaromatic containing group, said colorants being resistant to stannous octanoate, being characterized as having improved brightness and which have functionality through reactive substituents thereof.
