Hydrophilic surfaces carrying temporary protective covers
First Claim
1. A substrate having an exterior surface bearing a hydrophilic coating that is resistant to attack by a weak acid or a weak base, the hydrophilic coating carrying a temporary protective cover that is durable to glass tempering and is stable in the presence of water but breaks down in the presence of a weak acid or a weak base, wherein the substrate has an interior surface bearing a low-emissivitv coating comprising a metal layer sandwiched between a pair of dielectric layers.

Abstract
A substrate carrying a temporary protective cover and related methods of producing and processing substrates are described. In one embodiment, a substrate bears a hydrophilic coating carrying a temporary protective cover that protects the hydrophilic coating against contamination but that can readily be readily removed from the hydrophilic coating by washing with a given washing fluid.
