Low gloss dry erasable surface

摘要

A low gloss dry-erasable multilayer composite comprises a first layer having a dry-erasable outer surface and a second layer having a microroughened surface. Preferably, the second layer is microroughened by cure-induced surface wrinkling. The first layer preferably comprises a polymer comprising at least one pendant fluoroalkoxyalkyl functionality. Methods of making low gloss dry erasable multilayer composites are also provided. New dry-erasable coating compositions comprising certain amine resin crosslinking agents are also provided.
