Deealt with in the present report is the action of Epidian 5 hairdened with triethylenetetramine being a basic eompomnd. A sieries of tests have been undertaken aimed at establishing which pigments in the painted layers of paiintings are changing as a consequence of amine action. A number of samples consisting of canvas strips covered wiith paints containing different binders and pigments weere prepared for tests. As the next step the surfaces of' samples were covered with three kinds of substances, naimely (1) pure triethylenetetramine, (2) 20 per cent sollution of Epidian 6 in toluene with 12 per cent additiam of amine, and (3) 20 per cent solution of Epidian 5 wiith no amine addition. The apparent changes were observed in pigments as, e.g. red paint, Prussian blue, the green copper dye and those of yellow paint group who darkened. Most strongly reacted with amine the pigments containing the glue binder and those in which tempera was present. It has been found as a result of the tests carried out that the intensity of changes in colour is depending upor the nature of barrier formed by the binder film. It follows from the above that the application of epoxide resin hardened with triethylenetetramine is in each individual case to be preceded by a suitable testing of pigments. Pigments can be tested immediately within a selected small area of a painted layer.
