Matte Substrate

Matte substrates comprising a water based coating composition and a base substrate. The water based coating composition comprises either no or only small amounts of mineral filler, refractory filler and/or organic filler and no other matting agents. The water based coating composition is typically applied to the base substrate at a coating weight of less than or equal to about 3 dry pounds of the water based coating composition per about 3,000 square feet of the base substrate. The matte substrate generally has a 60° gloss less than about 20.

The invention pertains to matte substrates comprising water based coating compositions and base substrates. The water based coating composition comprises only small amounts of mineral fillers, refractory fillers and/or organic fillers and may comprise no mineral fillers, refractory fillers or organic fillers. Other matting agents are not used in the invention. Matte finish, i.e. a dull, no gloss finish having a lack of any or significant luster, is generally achieved by applying a coating material to a substrate. Many different types of substrates can be coated with a material to develop matte finish. One application for such coated substrates is paper stock for books, folders, magazine covers, and coated paper board for containers. Another example is paper that is coated to create matte finish photo paper and printer paper. Matte finishes are also used is in the area of labels, such as package labels.
