Abstract of the Disclosure This invention relates to a process for the production of hot melt coating compositions containing microcapsules and inorganic pigment particles comprising the following: A n aqueous dispersion of microcapsules is prepared. Inorganic pigment particles are added to the aqueous dispersion of the micro- capsules 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 adhere to the microcapsules. The free-flowing powder of the microcapsules having the inor- ganic pigment particles deposited thereon are then dispersion 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 0.1% to about 20%, by weight, inorganic pigment particles based on the weight of the microcapsules and a hot melt suspending medium. The inorganic particles are substantially deposited on and adhered to the microcapsules. - 1 -
