## Title
Coating for rubber gloves

## Abstract

A composition for a damp hand donnable glove using a novel coating. The novel coating results in the formation of domains of variable size and height. The coating has a polyurethane polymer, an aqueous wax dispersion and a surfactant.

## Background
FIELD OF THE INVENTION
This invention relates to a damp hand donnable glove produced using a novel coating formulation that yields domains variable in size and height on the surface of the glove.
BACKGROUND OF THE INVENTION
Medical, surgical and other gloves, made of a rubber latex, are typically manufactured so that these rubber articles tightly conform to the human hand. Because of this tight fit, such gloves are typically lubricated on the skin-contacting inner surface in order to facilitate donning of the articles. The standard lubricant utilized for this purpose is dusting powder, e.g., cross-linked corn starch. However, it is also desirable to have a glove that does not rely on an internal surface lubricant for donnability. Therefore, attempts have been made to eliminate the internal surface lubricants while at the same time providing an inner glove surface that will aid in the donning of the glove.
Various methods have been proposed to provide slip finishes on rubber articles of this type. For example, the surface of a rubber glove can be halogenated with bromine or chlorine to make it slippery. This treatment, however, has certain disadvantages well-known in the art and typically does not produce a glove that is easier to don that a glove internally coated with dusting powder. One prior art glove provides a slip finish comprising a rubber latex blended with a resin latex. This approach, while lowering the coefficient of friction of the rubber glove, does not significantly improve donnability. Yet another prior art glove is made with granular material deposited on the inner, skin-contacting surface of a single-layer vinyl or silicone glove in order to reduce the frictional contact between the glove layer and the skin of the wearer and, thus, to aid in the donning of the glove. Use of this glove, however, results in the granular material being abraded from the inner glove surface thus generating loose particulate matter. It is therefore desirable to have a glove with improved donnability that does not generate loose particulate matter. It is further desirable to have damp-hand donnable glove having domain formations on the glove surface that are produced during the manufacturing process.
SUMMARY OF THE INVENTION
In one embodiment, the present invention provides a damp-hand donnable glove produced using a novel coating formulation that yields domains variable in size and height on the surface of the glove. In another embodiment, the present invention also provides a formulation useful in producing gloves in a conventional dipping process where the gloves so made exhibit domain formation. In still another embodiment, the present invention further provides a process for the manufacture of a polymeric coating useful in the generation of domain formation on gloves made using the polymeric coating.

DETAILED DESCRIPTION OF THE INVENTION
There is provided according to the principles of the present invention, an aqueous-based polymeric coating including, in one embodiment of the present invention, water, a polyurethane dispersion, a sodium polymethacrylate solution and a polyvinyl chloride latex is prepared by first mixing the water, the polyurethane dispersion, and the polyvinyl chloride latex, to form a first mixture. Then, the sodium polymethacrylate is metered into the first mixture to form the coating of the present invention. Metered addition of the sodium polymethacrylate, under mixing, facilitates agglomeration of the polyvinyl chloride. Agglomeration of the polyvinyl chloride enhances the formation of domains on a glove surface.
According to the principles of the present invention, it has been demonstrated that the formation of domains on the interior of the glove surface greatly enhances donnability. The domains reduce the coefficient of friction between the interior glove surface and the skin, thus enhancing wet-hand donnability.
As but one example of a coating made according to the principles of the present invention, table 1 below presents a formulation useful as coating for the formation of domains on a glove surface.
