Abstract

Provided is: A glove dipping composition including, at least: an elastomer that contains a (meth)acrylonitrile-derived structural unit, an unsaturated carboxylic acid-derived structural unit and a butadiene-derived structural unit in a polymer main chain; a polycarbodiimide; zinc oxide and/or an aluminum complex; water; and at least one pH modifier selected from an ammonium compound and an amine compound, in which glove dipping composition the polycarbodiimide includes at least one polycarbodiimide containing a hydrophilic segment in its molecular structure and has an average polymerization degree of 3.8 or higher and a carbodiimide equivalent of 260 to 600; the polycarbodiimide is added in an amount of 0.1 to 4.0% by weight and zinc oxide and/or the aluminum complex is/are added in an amount of 0.1 to 5.6% by weight with respect to the total solid content of the glove dipping composition; and the glove dipping composition has a pH of 9.0 to 11.5.
