Abstract: The present invention relates to a matte coating composition comprising an aqueous dispersion of a) polymer particles having an average particle size in the range of from 80 nm to 500 nm; b) polymeric organic crosslinked microspheres having a particle size in the range of from 1 μm to 20 μm; c) polyethylene wax particles having a particle size in the range of from 0.3 μm to 30 μm; and d) a rheology modifier. The composition of the present invention gives matte finish coatings with excellent burnish resistance.

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.

Abstract: The present disclosure provides an aqueous composition. The aqueous composition includes multi-stage latex polymer particles. The multi-stage latex polymer particles include (A) a first-stage polymer containing (i) an n-methylol functional monomer and (ii) a first vinyl monomer; and (B) a second-stage polymer containing (i) a formaldehyde-scavenging monomer and (ii) a second vinyl monomer. The first-stage polymer is bound to the second-stage polymer.
