Aqueous adhesive dispersion containing polyurethane and ethoxylated fatty alcohol

摘要

The present invention relates to an aqueous adhesive dispersion comprising a dispersed polyurethane and an ethoxylated fatty alcohol as an emulsifier. The polyurethane is synthesized from a specific organic diisocyanate, a dihydroxy compound selected from specific polyester diols and polyether diols, and a compound having a group reactive to an isocyanate group and at least one ionic group. ing. The adhesive dispersion can be used as a bonding adhesive, for example, for bonding a composite film or for bonding a hard molded product with a flexible decorative sheet.
