摘要
A process is disclosed for improving the water-whitening resistance of a pressure sensitive adhesive containing an aqueous latex emulsion and water-soluble ions by removing the water-soluble ions and adjusting the pH of the pressure sensitive adhesive formulation to at least about 6.0. The preferred method of removing the water-soluble ions is to contact either the aqueous latex emulsion, the formulated pressure sensitive adhesive containing the aqueous latex emulsion, or both with ion exchange resin. The product produced by the process is also disclosed.
