DISCLOSED IS AN AQUEOUS EMULSION COMPOSITION COMPRISING, AS THE DISPERSOID, A (CO) POLYMER THAT COMPRISES AT LEAST ONE MONOMER UNIT SELECTED FROM ETHYLENIC UNSATURATED MONOMERS AND DIENIC MONOMERS, AND, AS THE DISPERSANT, (A) A POLYVINYL ALCOHOL POLYMER, AND CONTAINING (B) A CONDENSATE OF AN ALKALI METAL SALT OF AN AROMATIC SULFONIC ACID WITH FORMALDEHYDE IN A RATIO, (A)/(B), OF FROM 100/0.05 TO100/100 IN TERMS OF THE SOLID CONTENT OF THE TWO. THE COMPOSITION IS CHARACTERIZED BY ITS FLUIDITY OF SUCH THAT THE APPARENT VISCOSITY OF THE COMPOSITION IS PREVENTED FROM BEING LOWERED RELATIVE TO THE INCREASE IN THE SHEAR RATE OF THE COMPOSITION AND THAT THE APPARENT VISCOSITY OF THE COMPOSITION IS INCREASED RELATIVE TO THE INCREASE IN THE SHEAR RATE THEREOF. IN ADDITION, THE COMPOSITION IS FURTHER CHARACTERIZED BY ITS HIGH INITIAL ADHESIVENESS AND ITS VISCOSITY-INCREASING ABILITY.
