<p>PURPOSE:To provide the title composition outstanding in chemical resistance such as resistance to oil and water, capable of giving recording printed images of excellent clearness and recognizability, comprising a colorant made up of a mixture of white pigment with a fluorescent coloring matter, a binder, an organic solvent and an electrical conductivity-imparting agent. CONSTITUTION:The objective composition comprising (A) a colorant made up of a mixture of a white pigment (pref., titanium dioxide <=1.0mum in mean particle size) with pref. 0.5-5wt.% (based on said pigment) of a fluorescent coloring matter, (B) a binder (e.g., pyroxylin, rosin-modified xylene resin), (C) an organic solvent (pref., consisting mainly of ketone or alcohol), and (D) an electrical conductivity-imparting agent [e.g., alkali (alkaline earth) halide].</p> |
