Thermal transfer recording material

Abstract

Abstract PURPOSE:To provide the titled colorless recording material having pressure sensitivity and capable of imparting sharp thermal transfer image, constituted by combining thermal transfer recording paper formed by applying alkyl gallate and microcapsules having a solution of said alkyl gallate encapsulated therein to a base material and image receiving paper having an Fe-salt applied thereto. CONSTITUTION:Alkyl gallate with a m.p. of 80-160 deg.C (e.g., lauryl gallate), microcapsules each having a solution, prepared by dissolving said alkyl gallate in a solvent such as unvolatile oil, encapsulated therein and waxes are applied to a base material by a hot melt coater. Thus obtained thermal transfer recording material is combined with image receiving paper, to which an aqueous dispersion of an Fe-salt (e.g., iron stearate) is applied by a Mayer bar, to obtain the objective product.
