The present invention relates to water-resistant latexes and a process for their preparation, and to water-resistant adhesives based upon these latexes and a process for the preparation of the adhesives. The adhesives can be used to prepare laminates with improved water resistance. A blend of low pKa and high pKa acids is utilized in the instant invention to facilitate stabilization by the fugitive base ammonium hydroxide prior to stripping. Reduction of metal ion electrolytes in these materials greatly improves their water resistance without resorting to the use of nonaqueous systems for the preparation of the latex. |
