Abstract

In this study, several deteriorated pressure sensitive adhesive tapes (PSATs) applied in the past for repair-ing ripped paper documents of 19th century and books of 20th century were analyzed by attenuatedtotal reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy technique. The comparison of FTIRspectra of the old tapes with those of some commercially available tapes subjected to accelerated agingallowed us to identify, in a fast and nondestructive way, the main classes of old tapes on the basis oftheir backing (cellophane, cellulose acetate, polyvinyl chloride and polypropylene) and adhesive (natu-ral rubber, synthetic rubber and acrylic polymer) compositions. This procedure’s results were very usefulto the paper restorers and conservators, who will have the possibility of choosing the most appropriateconservation treatment for the removal of pressure sensitive adhesive tapes that can be found on manypaper documents.
