ABSTRACT:
An improved method of deacidifying books, imaged paper and other imaged materials having a cellulose base wherein, for a sufficient time to raise the pH of the materials, the materials are treated with alkaline particles of a basic metal oxide, hydroxide or salt dispersed in a hydrofluorether carrier, alone, or in combination with a perfluorinated carrier. A surfactant is added.
