  公开号：EP0479501A2

  公开（公告）日：1992-04-08

  A normally solid recording material is heat-melted in a path defined by a nozzle leading to an ejection outlet and is imparted with a thermal energy corresponding to a recording signal to generate a bubble. As a result, a droplet of the recording material is ejected out of the ejection outlet under the action of the bubble while the bubble is communicated with the ambience. The normally solid recording material preferably contains a colorant, a first heat-fusible solid substance having a melting point Tm of 36 - 150 °C and a boiling point Tb of 150 - 370 °C, and a second heat-fusible solid substance having a melting point Tm and a solidifying point Tf satisfying a relationship of Tm - Tf ≦ 30 °C.

  通常固态的记录材料在喷嘴确定的通向喷射口的路径上被热熔，并被赋予与记录信号相对应的热能以产生气泡。结果，记录材料的液滴在气泡的作用下从喷射口喷射出来，同时气泡与周围环境相通。通常固体记录材料最好包含着色剂、熔点 Tm 为 36 - 150 °C、沸点 Tb 为 150 - 370 °C的第一种热熔固体物质，以及熔点 Tm 和凝固点 Tf 满足 Tm - Tf ≦ 30 °C关系的第二种热熔固体物质。
