  • Publication number: 20220348802
    Abstract: The present disclosure provides an adhesive composition. The adhesive composition contains (A) multi-stage latex polymer particles, (B) a linear diamine base, and (C) an ethoxylated surfactant. The (A) multi-stage latex polymer particles include (i) a first-stage polymer containing acrylic acid monomer and a first vinyl monomer, and (ii) a second-stage polymer containing a meth acrylic acid monomer and a second vinyl monomer, with the proviso that the second vinyl monomer is different than the meth acrylic acid monomer. The first-stage polymer is bound to the second-stage polymer.
