Patent ID: 8043654

Claim:
A method of forming a detachable and renewable protective coating on a receptive surface comprising the steps of: (A) applying a treatment composition to said receptive surface, wherein said treatment composition is obtained by a process comprising the steps of: (a) providing a pre-dispersion of silica particles comprising hydrophobically modified fumed silica particles by stirring said silica particles into a solution with a first volatile solvent or a solvent mixture; (b) adding a suspending agent to said pre-dispersion; and (c) mixing with a disperser said pre-dispersion to provide a process composition while reducing said silica particles to a median particle size in the range between 100 and 4000 nanometers; (B) allowing said volatile solvent to evaporate from said receptive surface; and (C) thereby depositing said protective coating on said receptive surface, wherein said detachable coating is substantially transparent and results in a change of less than 3.0 Delta E units to said receptive surface measured before and after deposition of said coating.
