Dipped rubber article
First Claim
1. A flexible rubber article which has a coating comprising a lubricating hydrogel polymer bonded thereto to provide a surface of said article said surface coming in contact with the user'"'"'s skin, wherein a member of the group consisting of surfactant materials and long chain fatty amines has been applied to said surface so as to substantially improve the donning lubricity of said surface with respect to damp skin.

Abstract
A skin-contacting coating of a lubricating hydrogel polymer bonded to a rubber article (such as a surgeon'"'"'s glove) is treated by means of surfactant material (such as a bactericidal cationic surfactant which preferably has an N-hexadecyl group) or a long chain fatty amine so as to substantially improve the lubricity of the coating with respect to damp skin.
The hydrogel polymer is preferably a copolymer of 2-hydroxyethylmethacrylate (HEMA) with methacrylic acid (MAA) or with 2-ethylhexyl acrylate (EHA) or with both MAA and EHA. The copolymer contains HEMA and MAA is a molar ratio of 1 to 10:1 of HEMA and EHA in a molar ratio of 2.5 to 10:1. Such a hydrogel polymer has improved lubricity to dry skin and, if used for this purpose, need not be treated with a surfactant or fatty amine to improve the lubricity with respect to damp skin.
