4 CONCLUSION

Despite the success of the treament to remove the tape, use of Filmoplast-P for applications to emulsion surfaces is not recommended, and its use for application to the paper support is questionable. The tape almost certainly underwent some kind of change during its six years of contact with the photographic emulsion, and while no damage to the photographs was observed, the possibility of long term damage cannot be ruled out. Information on all components of the tape is not available. Moreover, the formulation of the adhesive has recently been changed according to the manufacturer4. As with all commercial products, procedures worked out on old samples may not besuitable for use on newer samples.
