Microcapsules used in coating compositions for thermal printing, especially for coating paper, have core of lipophilic substance with given solid-liquid phase transition and polymer shell

摘要

Microcapsules have a core of lipophilic substance(s) with a solid-liquid phase transition in the 40-120 deg C range and a polymer shell. Independent claims are also included for: (a) the production of such microcapsules; (b) the microcapsules produced by this process.
