Claim 0:
1. A waterborne coating composition for producing a matte film, the waterborne coating composition comprising:
a primary binder latex;
organic particles having an average diameter of about 10 to about 50 microns and including a polymeric core and polymeric shell, wherein the polymeric core has a glass transition temperature (Tg) of 80° C. or higher and the polymeric shell has a glass transition temperature (Tg) of 30° C. or less;
a pigment volume concentration (PVC) of about 28 or less; and
the waterborne coating composition, when dried as the matte film, exhibits a 60-degree gloss value of 5 or less and a 85-degree sheen value of 10 or less and with the polymeric shell combining with the primary binder latex to coalesce as the matte film and the polymeric core remaining as a particle within the dried matte film.
