Abstract: A process for the preparation of oil-containing microcapsules by interfacial condensation of a polyfunctional amine with a polyfunctional wall-forming material is disclosed. Microcapsules produced by this process have utility in the manufacture of carbonless copy paper. The process comprises emulsifying a mixture of a hydrophobic phase, which includes an oil, a chromogenic material and an oil soluble polyfunctional wall-forming material, and a hydrophilic phase, which includes water, a water soluble emulsifying agent and a water soluble salt of the desired polyfunctional amine. The amine salt may be formed in situ in the hydrophilic phase before the emulsification step.

Abstract: This invention relates to a process for the production of hot melt coating compositions containing microcapsules and inorganic pigment particles comprising the following: An aqueous dispersion of microcapsules is prepared. Inorganic pigment particles are added to the aqueous dispersion of the microcapsules and mixed. The dispersion of the microcapsules and the inorganic pigment particles are sprayed into a heated atmosphere, thereby drying the dispersion and producing a free-flowing powder of the microcapsules. The inorganic pigment particles are substantially deposited on and adhered to the microcapsules. The free-flowing powder of the microcapsules having the inorganic pigment particles deposited thereon are then dispersed in a liquid hot melt suspending medium. The liquid hot melt coating composition so produced can be coated on a substrate. The invention further relates to a coating composition comprising microcapsules, from about 0.
