A dip-forming composition of the present invention comprises a dip-forming latex containing a copolymer obtained by copolymerizing 100 parts by weight of a monomer mixture containing 70 to 85 parts by weight of a conjugated diene monomer, 10 to 28 parts by weight of an aromatic vinyl monomer, 2 to 5 parts by weight of an ethylenically unsaturated acid monomer and 0 to 18 parts by weight of other monomer copolymerizable with these monomers, said copolymer having a toluene insoluble content of 30% by weight or more and a toluene swelling degree of 70 times or less; and a vulcanizing agent, a vulcanization accelerator and zinc oxide which are blended in said latex in amounts of 0.5 to 2 parts by weight, 0.25 to 1 part by weight and 0.5 to 1 part by weight, respectively, on the basis of 100 parts by weight of a solid content of the latex. There can be provided a dip-formed article exhibiting an excellent touch and feel, sufficient tensile strength and elongation at break and an excellent persistence of close fitting, as well as a dip-forming composition capable of providing such a dip-formed article.
