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.
