Abstract
The present invention provides stain-inhibiting protection to glass surfaces of stacked glass sheets utilizing one or more water-soluble organic acid dispersed in a matrix of a water-soluble polymer or mixtures thereof. Suitable water-soluble organic acids may be found in the groups consisting of hydroxy mono, di, tri and tetra carboxylic acids. In the preferred form of the invention, components such as humectants, bactericidal and bacteriostatic agents and surface active (wetting) agents may be included in the composition.
