 note = {Recently, the value of modern documents as cultural properties has been accepted. However, there are problems in the conservation, preservation and restoration of modern documents because of the variety of materials used for them. Therefore, we should consider of methods for their conservation, preservation and restoration.
 In this study, we focused on the influences of fumigation on diazotypes which have been used often for engineering drawings. After samples were fumed with carbon dioxide or ethylene oxide, various examinations were carried out.
 There is little influence of fumigation with carbon dioxide or ethylene oxide on the folding endurance of diazotypes.
 Fumigation with ethylene oxide changed the color of diazotype as much as one can recognize by visual observation. However, change of the color of diazotype by treatment with carbon dioxide with moisture was not recognized visually although colorimetry shows that color became darker. Fumigation of diazotypes with carbon dioxide or ethylene oxide caused a smell like that of mercaptan. Surface pH of diazotypes increased by fumigation.
 Neither an ethylene oxide treatment nor a carbon dioxide treatment had little influence on the color and smell of cyanotype. On the other hand, pH increased by ethylene oxide treatment or carbon dioxide treatment.},
