Abstract
The present invention relates to an ink formulation which may be coated on a flexible substratum to produce a typewriter ribbon or the like, wherein impressions made from such a ribbon are capable of adhesive removal shortly after being created on all conventional typing bonds and papers, but which impressions exhibit delayed alteration resistance whereby any attempt at correcting or removing the indicia by pressure sensitive adhesive means or altering the indicia by erasing will leave an obvious and permanent indication that a removal was attempted.
