Abstract (en)
[origin: EP0545180A1] Neutralising agent for effective and gentle mass deacidification of books and other paper products, consisting of a solution of double alkoxides of one or more types each with an alkoxide of metals assisting the solubility, such as metals of subgroup IV, aluminium or tin, and an alkoxide of metals which bind the free acids in the paper, such as alkali metals or alkaline earth metals, it being possible to use a non-polar solvent, which is well compatible with the archive materials, for dissolution.
