| 摘要 |
A heat-sensitive, color-producing composition comprising at least one metallic compound and at least one chelating agent, said metallic compound and chelating agent being separated from each other by including either or both of them, separately, into a heat-fusible material, said heat-fusible material being capable of being fused when said composition is heated, thereby producing a color by chelation of said metallic compound with said chelating agent. The compositions can be used to prepare heat-sensitive recording members by dispersing them into a suitable binder and then coating onto a suitable base support. The compositions can be also used to prepare heat-sensitive paints.
