ABSTRACT:
This invention provides for improvement in the preservation of cellulosic materials through solubilization of a dried metal alkoxide, particularly magnesium methoxide, in an alcohol with the presence of carbon dioxide. The solution is applied to cellulosic materials by various known methods resulting in deacidification with improved aging properties imparted to the materials. The treated cellulosic materials have improved characteristics and printed materials do not blur or run.
