Condensation copolymers containing copolymerized isoquinoline derivative colorants and products therefrom

A composition comprising molding or fiber grade condensation polymer having copolymerized therein a total of from 10 to about 20,000 ppm, of a colorant comprising the reactant residue moieties of one or a mixture of isoquinoline derivative reactants of the formula ##STR64## wherein:

• R is hydrogen, cycloalkyl or alkyl;
• X is --O--, --S-- or --NH--;
• --X--R.sub.1 --Z in combination is hydrogen or halogen;
• R.sub.1 is selected from --alkylene--Z, --arylene--Z, --cycloalkylene--Z, --aralkylene--Z, --cycloalkylenealkylene--Z, --alkarylene--Z, --alkylenecycloalkylenealkylene--Z, --alkylenearalkylene--Z, or alkylenecycloalkylene--Z, wherein --Z is selected from hydrogen, --SO.sub.2 R.sup.5, --SO.sub.2 NR.sup.5 R.sup.5, --NHSO.sub.2 R.sup.5, --N(R.sup.5)SO.sub.2 R.sup.5, --N(R.sup.5)COR.sup.5, --NHCOR.sup.5, --OH, --SR.sup.5, --OR.sup.5, --NHR.sup.5, --NR.sup.5 R.sup.5, --SO.sub.2 NHR.sup.5, --CONHR.sup.5, --CONR.sup.5 R.sup.5, --OCOR.sup.5, --OCO.sub.2 R.sup.5, --OOCNHR.sup.5, ##STR65## wherein R.sup.5 is hydrogen, alkyl, allyl, aryl, cycloalkyl, hydroxyalkyl, alkoxyalkoxyalkyl, alkoxyalkyl, hydroxyalkoxy, hydroxyalkoxyalkoxy, alkoxycarbonylalkyl or carboxyaryl, and when X is --O-- or --NH--, --R.sub.1 --Z in combination also can be hydrogen;
• R.sub.2 is hydrogen, alkyl, aryl, cyano, alkoxycarbonyl, aryloxycarbonyl, aralkoxycarbonyl, cycloalkylalkoxycarbonyl, COCl, carboxy, carbamyl, N-alkylcarbamyl, N,N-dialkylcarbamyl, N-alkyl-N-arylcarbamyl, N-arylcarbamyl, N-cycloalkylcarbamyl, acyl, aroyl, amino, alkylamino, dialkylamino, arylamino, cycloalkylamino, alkoxy, hydroxy, alkylthio or arylthio;
• each of R.sub.3 and R.sub.4 is hydrogen, alkyl, halogen or alkoxy;
• wherein each of the above alkyl, alkylene, aryl, arylene, cycloalkyl or cycloalkylene moieties or portions of a group or radical may be substituted where appropriate with 1-3 substitutents selected from hydroxyl, acyloxy, alkyl, cyano, alkoxycarbonyl, alkoxycarbonyloxy, halogen, alkoxy, hydroxyalkoxy, hydroxyalkyl, aryl, aryloxy, or cycloalkyl;
• wherein, when the above hydroxyl substituent is absent or when multicondensable groups are desired, at least one of R, R.sub.2, R.sub.3 or R.sub.4 carries one or more condensable groups;
• and wherein in all of the above definitions the alkyl or alkylene moieties or portions of the various groups contain from 1-8 carbons, straight or branched chain, the aryl or arylene nuclei contain from 4-10 carbons, and the cycloalkyl or cycloalkylene nuclei contain from 4-6 carbons.
