<p>PURPOSE:To provide an additive for affording writing utensile or printing ink composition with water resistance and dissolution stability, comprising, as active ingredient, a reaction product from vinyl compound soluble to water, etc., active hydrogen-contg. compound, etc. CONSTITUTION:(A) A vinyl compound soluble to water or water-soluble organic solvent (e.g. acrylic acid) and (B) a second compound having at least two groups contg. active hydrogen (at least one of them being either amino group or imino one) (e.g. m-aminophenol) or (C) a third compound having both halogen group and amino or imino group (e.g., o-chloroamiline) are made to react, in the presence, if desired, of a solvent (e.g. ethylene glycol) and, if necessary, of a catalyst (e.g., hydrogen chloride), normally at 10-160 deg.C for 0.5-10hr. to prepare a product. This product is dissolved in water and/or water-soluble organic solvent to obtain the objective additive. The resulting additive is incorporated in color composition or ink composition.</p> |
