Abstract

Procedure for the manufacture of pressure-sensitive self-registering sheets, characterized in that a layer of microcapsules and a layer of color developer are applied to a support on the same surface, said microcapsules being prepared by emulsifying an oily liquid containing a color former capable of reacting with said color developer to form color, a first film wall forming material and a second film wall forming material capable of reacting with said first film wall forming material to form a high molecular weight compound, in a polar liquid, capable of forming a continuous phase, a third film wall-forming material, capable of reacting with said first film wall-forming material to form a high molecular weight compound, adding to said polar liquid before or after of emulsification, and forming a capsule wall around the oil droplets of dic or oily liquid, the capsule wall being formed from within the oil droplets by the reaction of the first film wall-forming material and the second film wall-forming material and, simultaneously, by the reaction on the surface of the oil droplets oil between the first film wall forming material and the third film wall forming material in said polar liquid.
