摘要： The polyisoprene-containing latex composition of the present it comprises the following components (a) and (b): (a) zinc ethylphenyldithiocarbamate; and (b) 1-o-tolylbiguanide. Thus, a molded article of the latex composition has high tensile strength. Further, even after the latex composition is stored for a longer period of time than before, a decrease in the tensile strength of the obtained molded article is suppressed.
