Abstract: The adhesive of the present invention includes latexes with an adhesion promoter which is preferably polyamidoamine. The addition of the polyamidoamine improves the adhesive strength between substrates such as between two plastic films or between a plastic film and paperboard. The present invention also relates to an adhesive prepared from a latex which is neutralized with a particular base and a hydrophobic polyamidoamine having particular amine values and viscosity whereby the strength of the adhesive bond is increased in humid conditions. The present invention also relates to an adhesive which is stable in the presence of water containing high levels of ions.

Abstract: 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.

Abstract: On décrit des latex résistants à l'eau et leur procédé de préparation, des adhésifs résistants à l'eau et à base de ces latex, ainsi que le procédé de préparation de ces adhésifs. On peut utiliser les adhésifs pour préparer des stratifiés présentant une résistance améliorée à l'eau. On utilise un mélange d'acides à faible pKa et à pKa élevé afin de faciliter la stabilisation par l'ammoniaque à base volatile avant la rectification. Une réduction des électrolytes d'ions métalliques dans ces matériaux améliore fortement leur résistance à l'eau sans recours à des systèmes non aqueux lors de la préparation du latex.
