This work is in progress to achieve a deeper insight to establish the application of the graft copolymerization method using vinyl comonomers as a new technique for document preservation and opens the way to preservation and restoration of cellulosic paper sheet , which belong to the field of cultural heritage . Our work alerts the forensic science community to the existence of the erasable ball pen and the possibility to contribute in the development of criminal activity in the field of forgery .
