Abstract | To provide a heat-sensitive recording material which is excellent in terms of high-speed printing performance among various properties required for heat-sensitive recording materials, which is also excellent in terms of oil resistance, plasticizer resistance, printing runnability and the like.SOLUTION: A heat-sensitive recording material has a primer coating layer on a supporting body, and also has a heat-sensitive recording layer on the primer coating layer, the heat-sensitive recording layer containing a colorless or pale electron-donating leuco dye and an electron-accepting color developer. The heat-sensitive recording layer contains, as the electron-accepting color developer, a urea compound. The primer coating layer contains 50-95 wt.% of a pigment in terms of solid content, while containing 50 wt.% or more of plastic hollow particles relative to the pigment in terms of solid content.SELECTED DRAWING: None
【課題】感熱記録体に求められる様々な性能のうち高速印字性に優れ、更に耐油性、耐可塑剤性、印字走行性等に優れる感熱記録体を提供する。【解決手段】支持体上に下塗り層を設け、該下塗り層の上に無色ないし淡色の電子供与性ロイコ染料と電子受容性顕色剤とを含有する感熱記録層を設けた感熱記録体において、該感熱記録層が、電子受容性顕色剤として、ウレア化合物を含有し、該下塗り層が、顔料を固形分で50~95重量%含有し、プラスチック中空粒子を顔料に対して固形分で50%重量以上含有する、感熱記録体である。【選択図】なし |
