Abstract
Disclosed is a dip-formed article obtained by dip-molding a latex composition for dip-forming, which contains a crosslinking agent and a latex for dip-forming containing a copolymer composed of 40-80% by weight of conjugated diene monomer units (A) containing an isoprene unit, 20-45% by weight of ethylenically unsaturated nitrile monomer units (B), and 2-15% by weight of ethylenically unsaturated acid monomer units (C), and having a weight ratio of butadiene unit content to isoprene unit content that falls within the range of 60:40 to 100:0. Tear strength is at least 50 N/mm, tensile strength is at least 25 MPa, and oil swelling rate does not exceed 5%.
