IN A PROCESS FOR PREPARING AN ALKALI REISTANT, ACID SENISTIVE INTERPOLYMER LATEX BY INTERPOLYMERIZING A TOTAL OF FROM ABOUT 5 TO 25 PERCENT BY WEIGHT OF A MONOMERIC ETHYLENICALLY UNSATURATED AMINE, AND FROM ABOUT 75 TO 95 PERCENT BY WEIGHT OF AT LEAST ONE ALPHA-BETA UNSATURATED POLYMERIZABLE CO-MONOMER BY AN AQUEOUS EMULSION INTERPOLYMERIZATION REACTION, THE IMPROVEMENT WHICH COMPRISES CARRYING OUT SAID INTERPOLYMERIZATION BY A MULTISTAGE POLYMERIZATION PROCESS, IN WHICH AT LEAST ONE STAGE CONPRISES ADDING AND PLYMERIZING AN ETHYLENICALLY UNSATURATED AMINE-MONOMER ENRICHED FRACTION, THE ETHYLENICALLY UNSATURATED AMINE-MONOMER PROPORTION OF SAID AMINEUNSATURATED AMINE-MONOMER PROPORTION OF SAID AMINEMONOMER ENRICHED FRACTION BEING ALWAYS GREATER THAN SAID TOTAL PERCENT OF ETHYLENICALLY UNSATURATED AMINE-CONTAINING MONOMER IN SAID INTERPOLYUMER AND BEIG PRESENT IN AN AMOUNT OF FROM 10 TO ABOUT 100 PERCENT BY WEIGHT OF SAID FRACTION, AND WHEREIN SAID FRACTION CONSTITUTES FROM 10 TO 70 PERCENT BY WEIGHT OF THE TOTAL MONOMERIC CONSTITUENTS, AND THE OTER STAGE OR STAGES OF WHICH COMPRISES ADDING AND POLYMERIZING THE REMAINDER OF SAID MONOMERIC CONSTITUENTS IN A FRACTION OR FRACTIONS NONENRICHED IN THE ETHYLENICALLY UNSATURATED AMINE-MONOMER COMPONENT, TO PROVIDE SAID INTERPOLYMER LATEX.
