The invention relates to an article, useful as a dry erasable substrate and projection screen, comprising a top layer which is dry erasable and whose surface has a 60° gloss of less than about 60. The article provides a projection surface which has low gloss and therefore causes little eye strain and viewer fatigue. The dry erase board provides good write/rewrite characteristics, erasability, including wet erasability and has good image projection. The article may additionally have one or more of layers which include a pressure sensitive adhesive, support layer, a pigmented layer which is a pressure sensitive adhesive or a pigmented polymer or polymer blend, and a back coat which is optionally pigmented.
