Beschreibung
Zusammenfassung:	An aqueous coating composition including: certain first solid polymeric particles having an average diameter of 0.60-0.99 um and certain second solid polymeric particles having a calculated Tg of from -60DEG C to 120 DEG C and an average particle diameter of from 50 nm to 500 nm; wherein the dry weight ratio of the first solid polymeric particles to the second solid polymeric particles is from 0.15:1 to 10:1; and the aqueous coating composition includes less than 10% by volume, inorganic extender particles is provided. Also provided is a coating having a ratio of 85 degree specular gloss to 20 degree specular gloss equal to or greater than 33 formed from the aqueous coating composition.
