Abstract

Procedure for the production of a pressure sensitive recording paper, characterized in that one, two or more wall-forming materials are dissolved, capable of forming a compound of high molecular value, insoluble, both in oil and in water, reacting each other, within an oily liquid, containing a color former, a low boiling point solvent, or a polar solvent, compatible with another, that forms a continuous phase to prepare a solution, by which the solution is emulsified in the polar solvent, which forms a continuous phase, and by which the temperature of said system is raised to transfer the wall-forming material or materials to the surface of the oil droplet and by continuing the reaction between the forming material or materials wall on the surface of said drop of oil, whereby microcapsules are produced, containing the color former, which are then applied to a support.
