| titleOfInvention | Method for encapsulating dissolved color reaction partners of color reaction systems, the capsules obtained according thereto, and their use in color reaction papers |
| abstract | The invention relates to a method for encapsulating a solution, which consists of color reaction partners of color reaction systems while being provided in an aqueous emulsion, by using conventional microencapsulation methods. According to the invention, the color reaction partner is firstly dissolved in a solvent, and a nonsolvent that, at most, slightly dissolves the color reaction partner is admixed with rapid mixing to the solution obtained in the aforementioned manner. The nonsolvent is admixed in an amount that results in a supersaturated solution. The supersaturated solution is immediately emulsified with rapid mixing in the aqueous phase, and the encapsulation is carried out immediately afterwards. A vegetable oil C1-C8 alkyl ester is used in the solvent. This method exhibits both economic and technological advantages while enabling the production of microcapsules having an advantageously tight monomodal particle distribution that leads to an improved print rate. |
