摘要： The present invention provides a dip-formed article that has an excellent stress retention rate and is easily stretched and soft. The present invention provides a dip-formed article comprising a layer derived from a latex composition for dip-forming, wherein the latex composition for dip-forming contains a carboxylic acid-modified nitrile-based copolymer latex, the carboxylic acid-modified nitrile-based copolymer latex contains a carboxylic acid-modified nitrile-based copolymer, and the dip-formed article has an elongation of more than 650% and satisfies the following Expressions 1 and 2,
[Expression 1] k 1 ′ + k 2 ′ + k 3 ′ ≤ 9.3 N / mm [Expression 2] 0.55 ≤ k 1 ′ / k 1 ′ + k 2 ′ + k 3 ′ wherein k 1 ' is a value obtained by dividing an equilibrium coefficient k 1 by a thickness of a test piece, and k 2 ' and k 3 ' are values obtained by dividing viscous coefficients k 2 and k 3 by the thickness of the test piece, respectively.-
