Abstract
An adhesive composition that includes a) an emulsion that includes a multi-stage polymer that includes a first stage polymer having a Tg from −20° C. to 90° C. and including from about 0.5% by weight to about 3% by weight latent crosslinking monomer based on the first stage monomer weight, and a second stage polymer having a Tg from 40° C. to 140° C., the second stage polymer being different from the first stage polymer, b) formaldehyde-based crosslinking agent, and c) catalyst, the composition being capable of passing the DIN EN 204 Test Method.
