Abstract
This invention relates to a dry erase writing board. The dry erase writing board comprises a chalk or erase board having a face side, and a multilayer film which is adhered to the face side of the chalk or dry erase board. The outer or exposed surface of the multilayer film which is adhered to the chalk board or erase board is a clear dry erasable layer comprising at least one fluorocarbon polymer. The invention also relates to a method of preparing the dry erase writing boards of the invention which utilizes a multilayer film having an adhesive layer for adhering the multilayer film to the chalk or erase board and a pattern of non-adhesive material forms embedded into the upper or lower surface of the adhesive layer, or adhered to the lower surface of the adhesive layer. The dry erasable multilayer films described herein are easily applied to substrates such as a chalk or erase board with little or no formation of visible bubbles or wrinkles in the film.
