Abstract
The present invention relates to an aqueous laminating adhesive composition and a method of using thereof. More particularly, the invention relates to an aqueous laminating adhesive composition comprising at least one aqueous polyurethane polymer dispersion (A), at least one aqueous non-polyurethane polymer dispersion (B) prepared by free radical polymerization, and at least one water dispersible polyfunctional crosslinking agent (C). Improved bonded properties of dry laminated flexible film substrates such as polyolefin, polyester and polyamide, as well as cellophane, metals or paper are obtained.
