| description | The present invention provides a chloroprene-based polymer latex composition, which has a low residual amount of mercaptans with hygiene concerns remaining, and which can obtain a chloroprene-based polymer dip-molded article having excellent flexibility and high breaking strength even with use of less vulcanization accelerator and sulfur, due to the plasticizing effect of a low molecular weight polymer and the use of a heteroaromatic ring-based compound.According to the present invention, there is provided a chloroprene-based polymer latex composition including a chloroprene-based polymer latex, a metal oxide, and a heteroaromatic ring-based compound, wherein the chloroprene-based polymer latex composition includes 0.5 to 15.0 parts by mass of the metal oxide and 0.1 to 10.0 parts by mass of the heteroaromatic ring-based compound per 100 parts by mass of solid content of the chloroprene-based polymer latex, the chloroprene-based polymer latex composition has a content of alkyl mercaptan compounds of 0.34 parts by mass or less per 100 parts by mass of solid content of the chloroprene-based polymer latex, and the heteroaromatic ring-based compound is represented by chemical formula (1). |
