摘要： 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.

摘要： The invention relates to a method for producing a thermal paper comprising a carrier substrate, an intermediate pigment coat, a thermal reaction coat and optionally one or more additional intermediate coats and/or top coats, said intermediate pigment coat being formed from a pigment, binding agents and optionally an aqueous application suspension containing additional application additives, by means of a curtain coating method. Said method is characterised in that an aqueous application suspension containing calcined kaolin, with a solid content of between approximately 25 and 75 wt. %, is applied at an operating speed of at least approximately 500 m/min in a curtain coating method and is dried. Said method is technically simple and economical to perform. In particular, the method enables the use of the curtain coating method at a higher speed of more than 750 m/min and in particular more than 1500 m/min.
