Process for increasing the affinity for anionic dyes of high molecular weight organic compounds containing alkylatable groups

Abstract

Abstract PROCESS FOR INCREASING THE AFFINITY FOR ANIONIC DYES OF UNDYED WATER-INSOLUBLE HIGH MOLECULAR WEIGHT ORGANIC COMPOUNDS CONTAINING GROUPS WHICH CAN BE ALKYLATED, WHICH PROCESS COMPRISES REACTING THE HIGH MOLECULAR WEIGHT COMPOUND WITH AN AMMONIUM SALT OF THE FORMULA: X-CH2-Y-CH2-N(+)(-R1)(-R2)-R3 X(-) IN WHICH X SIGNIFIES CHLORINE OR BROMINE, Y SIGNIFIES A RADICAL OF FORMULA -CH=CH- OR A PHENYLENE RADICAL WHICH IS UNSUBSTITUTED OR SUBSTITUTED BY UP TO A TOTAL OF 2 ALKYL GROUPS WHICH MAY BE METHYL OR ETHYL, R1, R2 AND R3, INDEPENDENTLY SIGNIFY HYDROCARBON RADICALS CONSISTING OF AROMATIC AND/OR SATURATED ALIPHATIC UNITS, OR TWO OF R1, R2 AND R3 JOINTLY WITH THE N ATOM FORM A HETEROCYCLIC RING, WHICH IS SELECTED FROM HETEROCYCLIC RINGS CONTAINING ONE NITROGEN ATOM, TWO NITROGEN ATOMS AND ONE NITROGEN ATOM AND ONE OXYGEN ATOM, AND THE OTHER SIGNIFIES A HYDROCARBON RADICAL AS DEFINED ABOVE OR A FURTHER BOND WHEN THE RING IS UNSATURATED, THE TOTAL NUMBER OF CARBON ATOMS IN R1, R2 AND R3 NOR BEING GREATER THAN 20, AND THE N ATOM NOT BEING BOUND DIRECTLY TO MORE THAN ONE AROMATIC RADICAL.
