Abstract

PURPOSE:To prevent the colorization of a capsule wall or the lowering of a color developing temp. by a method wherein a multivalent isocyanate solution is dissolved and mixed in a capsule core substance containing oily solution and the resulting solution and an emulsifier containing aqueous solution are continuously supplied to an emulsifying machine to be emulsified and mixed. CONSTITUTION:In supply tanks 1, 2, 3, an emulsifier containing aqueous solution (a solution), a capsule core substance containing oily solution (b solution) and a multivalent isocyanate solution (c solution) are stored respectively. Those three kinds of solutions are supplied in a predetermined amount through strainers 7, 8, 9 and flow meters 10, 11, 12 by quantitative supply pumps 4, 5, 6. The (c) solution is mixed with the (b) solution in an in-line mixer 13 and, imediately after, the resulting mixed solution is continuously emulsified into the solution by a pipe-line homomixer 15. As the capsule core substance, various basic colorless dyestuff can be used and, as the emulsifier, gelatine or gum arabic can be used.
