    • A microcapsule-containing oil-based coating liquid wherein the coating liquid comprises a hydrophobic core material-containing microcapsule particles dispersed individually in a state of primary particle in an oil varnish for ink use or a resin for coating use, and a solvent having an affinity for both the varnish or the resin and the surface of the microcapsule wall material in a state of having been attracted with the affinity to both the varnish or the resin and the surface layer of the microcapsule wall material. The preferred solvent is a lower divalent or multivalent alcohol. A preparative method of the foregoing coating liquid by utilizing vacuum distillation is also proposed. A sheet, like a duplicating sheet of paper coated with the foregoing oil-based coating liquid is further provided. According to the present invention, a water-based microcapsules system can be advantageously converted into an oil-based one without coagulating the primary microcapsule particles. There is no hardening and breakdown of the wall material during the process, and the original strength and the flexibility of the microcapsule wall material can be retained intact. Conventional pressure transferring-type printing machine may be employed to printing a selected area of the sheet.
    • 一种含微胶囊的油性涂布液,其中,所述涂布液包含分散在油墨用油性油墨中的一次粒子状态的分散的含疏水性芯材料的微胶囊粒子,或者涂布用树脂,以及具有亲和性的溶剂 对于清漆或树脂以及微胶囊壁材料的表面以与清漆或树脂和微胶囊壁材料的表面层的亲和性吸引的状态。 优选的溶剂是低级二价或多价醇。 还提出了通过利用真空蒸馏的上述涂布液的制备方法。 进一步提供如同涂覆有上述油性涂料的复印纸一样的片材。 根据本发明,可以有利地将水性微胶囊体系转化为油性微胶囊体系而不使一级微胶囊颗粒凝结。 在该过程中没有壁材料的硬化和分解,并且微胶囊壁材料的原始强度和柔韧性可以保持完整。 传统的压力传送型印刷机可用于印刷片材的选定区域。
