    • The present invention relates to an imaging system, which comprises a support having a front and rear surface, at least one transfer layer coated on the front surface of the support, and at least one thermal recording layer coated on top of the outermost transfer layer, wherein the thermal recording layer contains heat-responsive microcapsules capable of separating an inner phase within the microcapsules from an outer phase contained outside the microcapsules, wherein said inner phase is capable of reacting with said outer phase to create a color forming element, and wherein the transfer layer is capable of transferring and adhering an image from said front surface of said support upon the application of heat energy to the rear surface of the support, said transfer layer strips from said front surface of the support by liquefying and releasing from said support when heated, said liquefied transfer layer providing adherence to a receptor element by flowing onto said receptor element and solidifying thereon, said adherence does not require an external adhesive layer, with the proviso that the transfer layer is not capable of reacting to form an image
    • 本发明涉及一种成像系统,其包括具有前表面和后表面的支撑件,涂覆在支撑体的前表面上的至少一个转印层和涂覆在最外侧转印层顶部上的至少一个热敏记录层, 其中所述热记录层含有能够将所述微胶囊内的内相与包含在所述微胶囊外部的外相分离的热响应微胶囊,其中所述内相能够与所述外相反应以产生成色元素,并且其中 转印层能够在将热能施加到支撑体的后表面上时从所述支撑体的前表面转印和粘附图像,所述转印层从支撑体的前表面通过液体和从所述支撑件释放而从所述支撑件上液体和释放 所述液化转移层通过流入所述受体元件而提供对受体元件的附着 在其上固化,所述粘附不需要外部粘合剂层,条件是转印层不能反应形成图像

    • 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。
