Abstract
A copolymer latex with a total solids content of at least 67% by weight, which is characterized by having a viscosity of 2,000 centipoises or less as measured with a BM viscometer under the conditions of total solids content of 67% by weight and at room temperature, is provided. Such a low viscosity and high solids-content copolymer latex is produced through an emulsion polymerization in which the method of use of the emulsifier and the amount thereof are controlled following specific conditions.
