Abstract
Water-based adhesive emulsion compositions comprising 30 to 60 wt % water and 40 to 70 wt % non-water adhesive components (solids), the adhesive solids comprising: (a) 90 to 99.9 wt % of a VAE polymer; (b) 0.1 to 10 wt % of a water-dispersible polyester; and (c) 0 to 1 wt % of an emulsifier ( preferably 0.1 to 1 wt % emulsifier), and a multi-layer material comprising at least one layer of a substrate and at least one layer of the above described adhesive emulsion composition.
