RESUMEN Una composición acuosa de recubrimiento de acabado mate, que incluye: al menos una dispersión acrílica con una pluralidad de partículas reticuladas que comprenden una pluralidad de primeras partículas acrílicas que tienen una mediana del tamaño de partícula promedio en peso menor que o igual a 4 micras de diámetro y un módulo de Young en la superficie mayor que o igual a 450 megapascales; un proceso para producir la composición acuosa de recubrimiento mate anterior; y un sustrato recubierto con un recubrimiento seco elaborado usando la composición acuosa de recubrimiento mate anterior. An aqueous matte finish coating composition, including: at least one acrylic dispersion with a plurality of crosslinked particles comprising a plurality of first acrylic particles having a median weight average particle size of less than or equal to 4 microns in diameter and a surface Young's modulus of greater than or equal to 450 megapascals; a process for producing the above aqueous matte coating composition; and a coated substrate coated with a dry coating made using the above aqueous matte coating composition.
