Abstract (en)
[origin: EP0192378A2] Improved imaging device for applying temporary indicia to substrates of the type having a base covered with a relatively light color, opaque, open cell microvoid-containing layer that is rendered translucent when the microvoids are filled with a liquid having a refractive index similar to that of the layer. The improvement in the imaging device involves insuring that the imaging liquid contains no substance having an evaporation rate less than about one-half of the liquid, thereby permitting the imaging device to be repeatedly applied to the same area of the substrate without leaving ghost images.
