Abstract
A sheet material for use as a dissolvable decal comprises a dissolvable paper or polymer layer whose dissolvability in water is enhanced using a temporary water barrier. In one embodiment, the sheet material comprises a dissolvable paper stock layer coated with the temporary water barrier layer in the form of an acrylate polymer. To create the decal, one or more ink layers are applied, either on top of the temporary water barrier, or between the temporary water barrier and a top face of the dissolvable paper stock. The sheet material also comprises a removable release liner comprising a sheet with a silicone release coating on one side. In use, the paper/plastic liner is removed and the resulting decal is then positioned on a vehicle. The decal remains on the vehicle, but it is ultimately removable under high pressure water conditions.
