Abstract

Drawings on paper have very often been reinforced with another cellulosic support. As the paste (starch or collagen) becomes yellow and brittle with time, it is necessary to remove it. Proteolytic and amylolytic enzymes may help to hydrolyse the pastes. A knowledge of the physico-chemistry of papers and pastes helped us in the understanding of the diffusion of enzymes through papers and substrate accessibility. The use of a non ionic surfactant (Brij 35) to improve the diffusion rate and substrate accessibility and lower primary alcohols to stabilise pigments have been studied.
