“…Calcium is associated with alkaline carbonates such as CaCO 3 which is generally regarded as beneficial to paper stability. High Ca concentration means that the paper sample has a large alkaline buffer and is of good archival quality 6 . This would also mean that the effectiveness of Fe as an oxidative catalyst is greatly reduced 9 .…”

“…This was mainly due to the shift from potassium aluminum sulphate (alum) to aluminium sulphate as a sizing agent 5 . It has been observed that such a change in sizing agent was associated with increasing acidity of the paper produced 6 . Transition metals like iron (Fe), copper (Cu) and manganese (Mn) play a significant role in influencing the oxidative degradation of cellulose through their catalytic action.…”

Energy dispersive X-ray fluorescence technique was used to study the elemental composition of some historical paper samples obtained from the National Library of South Africa. Six elements namely Fe, Cu, Mn, Ca, K and S were detected. It was found that older documents had higher concentrations of Ca and hence a considerable alkaline buffer than recent documents. It was also observed that the levels of Ca dropped significantly between 1800 and 1890 coinciding with the period paper making technology also changed. The concentrations of K and S also went down around 1890. Fe remained fairly high and was detected in all samples. Cu and Mn were found to be at very low concentrations compared to Fe. This research shows that Fe has the potential to impact negatively on paper permanency unless de-acidification is undertaken because of its relative abundance compared to Cu.

A set of chromolithographs from the 19th century were analysed to identify the fillers and pigments used for their elaboration. Because of the delicacy of the chromolithographs, the research involved the use of Raman, Fourier‐transform infrared and energy dispersive X‐ray fluorescence spectroscopies for a complete characterization of the works on paper without removing any microsamples. Despite the high fluorescence of the samples when analyzed by Raman spectroscopy, in this paper, we demonstrated that ink spectra can be successfully enhanced by subtracting the spectra of the supporting background paper. The results of the study showed that, apparently, the lithographer used a limited range of common inorganic pigments from the 19th century (carbon black, chrome yellow, Prussian blue, red ochre, red lead and vermilion) together with organic pigments (indigo blue, gamboge and a red organic pigment). The study also found that despite the fact that during the 19th and early 20th century the use of mixtures of several pigments was a common practice, unusual admixtures were used for the preparation of some colours of the studied chromolithographs.

“…Absorption bands located in the "fingerprint region" of both spectra that ranged from 1200 cm -1 to 800 cm -1 corresponded well to the vibrations of the main functional groups or bonds in the chemical structure of cellulose. These functional groups were as follows: a strong absorption band at 1025 cm -1 due to C-O stretching of C-OH and C-O-C in pyranose rings, a small sharp peak at 894 cm -1 attributed to the glycosidic C-H deformation with ring vibration contribution, a sharp band at 1158 cm -1 assigned to the stretching vibration of β-glycosidic linkage between pyranose rings, and a rather sharp band at 1313 cm -1 attributed to CH2 wagging vibration (Brugnerotto et al 2001;Manso and Carvalho 2009;Chen et al 2011;Kotelnikova and Mikhailidi 2011;Jahan et. al.…”

The surface chemistry of gravure printed décor paper and its effect on the adhesion of melamine formaldehyde (MF) coatings were studied. Two industrially printed decor papers with different designs were used for the study. A combination of the attenuated total reflectance Fourier transform Infrared (ATR FT-IR) and FT-IR spectroscopy techniques were employed to determine the effect of the gravure printing ink on the printed paper surface chemistry. Then, the influence of the surface chemistry on the adhesion of MF coatings was characterized according to the abrasion resistance test. The ATR IR results suggested that the printing ink components had a noticeable effect on the surface characteristics of the printed décor paper. In addition, it was indicated that the use of an organosilane adhesion promoter in the gravure ink formulation could significantly affect the adhesion strength of the MF coatings through the formation of ring siloxane structures. It seemed that siloxane bridges formed between the molecules of ink binder and UF resin could enhance the adhesion strength of subsequent MF coatings and could reveal better Taber abrasion resistance performance.
