A WATER-BASED COATING COMPOSITION WHICH CONSISTS ESSENTIALLY OF (1) WATE, (2) 100 PARTS BY WEIGHT OF EMULSIFIED POLYMER SOLIDS, (3) ABOUT 6-36 PARTS BY WEIGHT OF AN ALKALI SOLUBLE INERPOLYMER OF STYRENE AND A MALEIC MONOMER SELECTED FROM THE GROUP CONSISTING OF MALEIC ANHYDRIDE, MALEIC ACID, HALF ESTERS OF MALEIC ACID AND A 1-18 CARBON ATOM MONOHYDRIC ALCOHOL AND MIXTURES THEREOF, (4) ABOUT 25-200 PARTS BY WEIGHT OF AT LEAST ONE PIGMENT, AND (5) SUFFICIENT ALKALI TO PROVIDE A PH IN THE RANGE OF ABOUT 8-12; AT LEAST 15% BY WEIGHT OF THE EMULSIFIED POLYMER SOLIDS OF (2) BEING A THERMOPLASTIC POLYMER HAVING A SECOND ORDER TRANSITION TEMPERATURE NOT HIGHER THAN ABOUT 50*C. AND CONSISTING OF THE EMULSIFIED POLYMER SOLIDS OF (A) AN ALPHA, BETA-ETHYLENICALLY UNSATURATED CARBOXYLIC ACID, AND (B) AT LEAST ONE VINYLIDENE MONOMER, WHEREIN THE POLYMER PARTICLES THEREOF COMPRISE AN INNER POLYMER COMPOSITION WITH A PARTICULAR POLYMER COMPOSITION ORIENTED TO THE SURFACE OF THE PARTICLES; SAID INNER POLYMER CONSISTING OF AT LEAST 70 WEIGHT PERCENT BASED ON THE WEIGHT OF THE POLYMER PARTICLES OF A POLYMER SELECTED FROM THE GROUP CONSISTING OF HOMOPOLYMERS AND INTERPOLYMERS OF (B) AND SAID POLYMER ORIENTED TO THE SURFACE OF THE PARTICLES CONSISTING OF AN INTERPOLYMER OF 1875 WEIGHT PERCENT OF (A) BASED ON THE WEIGHT OF THE SAID ORIENTED POLYMER WITH THE BALANCE THEREOF BEING (B); SAID POLYMER PARTICLES HAVING A PARTICLE SIZE OF 0.01-1.0 MICRON; SAID THERMOPLASTIC POLYMER CONSISTING OF THE EMULSIFIED POLYMER SOLIDS OF (A) ABOUT 25-60% BY WEIGHT OF A MATERIAL SELECTED FROM THE GROUP CONSISTING OF STYRENE AND MIXTURES OF STYRENE WITH ALPHA-METHYLSTYRENE, (B) ABOUT 30-60% BY WEIGHT OF AT LEAST ONE ESTER FORMED BETWEEN A 1-18 CARBON MONOHYDRIC ALCOHOL AND AN ACID SELECTED FROM THE GROUP CONSISTING OF ACRYLIC ACID AND METHACRYLIC ACID AND MIXTURES THEREOF, (C) ABOUT 2-20% BY WEIGHT OF A MATERIAL SELECTED FROM THE GROUP CONSISTING OF ACRYLONITRILE, AND METHACRYLONITRILE, AND MIXTURES THEREOF, AND (D) ABOUT 5.5-20% BY WEIGHT OF AN ACID SELECTED FROM THE GROUP CONSISTING OF ACRYLIC ACID AND METHACRYLIC ACID, AND MIXTURES THEREOF.
