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.
Claims6
A method for treating cellulosic materials comprising the steps of preparing a solution of a metal alkoxide in an alcohol, drying said solution to provide a dried metal alkoxide, dissolving the dried metal alkoxide in alcohol in the presence of carbon dioxide to provide a second solution, and applying the second solution to a cellulosic material.
