Abstract

PURPOSE:To improve light and humidity resistances by a method wherein at least one of specific dithiocarbamate metal salts is mixed with no-carbon copying paper. CONSTITUTION:Specific dithiocarbamate compound shown in the formula (n=2 or 4; R1, R2 showing alkyl or phenyl radicals of C1-4; M showing any one of Co, Ni, Cu, Zn, Te, Pd, Mg) is crushed single or mixedly by a crusher like a ball mill, a cage mill, an atomizer to obtain concentrations 20-40% of solid matters and a mean particle diameter about 5mu. When it is crushed, dispersion agent, activated clay or acid clay, water soluble binder are affixed and an activiator having anion or nonion radicals like phospharic acid, sulfonic acid aorbonic acid or the like is added to stabilize the dispersion liquid. A copy sheet obtained by coating said dispersion liquid can stabilize the hue and light resistance and humidity resistance also are improved.
