The influence of carboxylate-alumoxane protective coatings on the condition of writing paper inked with iron and copper gall inks has been investigated. All paper samples used in this study were coated with hexanato-alumoxane at room temperature changing the soaking time from 1 to 8 h. The influence of deconservation parameters (duration and temperature) on the stability of inks was also studied. Paper samples (untreated, coated and after deconservation) were examined by X-ray diffraction (XRD) analysis and scanning electron microscopy (SEM). Analytical characterization of paper samples showed no degradation of its cellulosic substrate during conservation. However, the destructive effect of alumoxane on the writing iron gall inks was determined.
