Title: Emulsion ink for porous printing
Inventor: TATEISHI HIROSHI
IPC: C09D11/02
Filed: 1991-10-17
Abstract: PURPOSE:To obtain the title ink which can give a print effectively prevented from being copied with a Carson-type copying machine by forming a W/O emulsion in which the aqueous phase contains thermoreversibly discolorable resin particles which decrease in the optical density of image at a certain temperature. CONSTITUTION:The title ink is obtained by forming a W/O emulsion comprising about 10-50wt.% oil phase and about 90-50wt.% water phase which contains thermoreversibly discolorable resin particles which decrease in the optical density of image at a certain temperature. This ink can give a print which can no longer be recognized as a copy when copied with, e.g. an electrophotographic copying machine. When the mean particle diameter of the particles is 1-10mum, the ink can give an image of a sufficient optical density. When the water phase contains a thickener, the ink has excellent stability. This ink is very effective because it can give a classified document which cannot be duplicated.
