Ink coatings for security documents to prevent forgery by means of heat sensitive erasable ink |
摘要 |
Disclosed is a solvent-borne or UV-curable fugitive ink composition for application to a substrate that is to be provided with indicia. The ink composition comprises at least one halochromic compound and at least one filler compound and is capable of preventing indicia formed with a heat sensitive erasable ink on an area of the substrate carrying the fugitive ink composition and thereafter subjected to a thermal treatment from becoming invisible to an unaided eye. |
