Abstract
The invention provides low temperature thermally activatable water-dispersed adhesive compositions and adhesives made therefrom. The adhesive compositions comprise a mixture of low modulus crystallizing polyester polyurethane, acrylic ester copolymer, thermoplastic resin, one or more hydrophobically-modified associative polyurethanes, and a stabilizer system comprising a combination of carbodiimide and branched primary amino alcohol.
