ABSTRACT:
A coating formulation which forms a heat sensitive coating and a thermal recording material with such a coating are disclosed. The heat sensitive coating shows improved prerecording shelf life and improved record stability and consists of microcapsules containing a solid blend of dye and sensitizer, with the exterior of the capsules consisting of color developer and other coating materials such as pigment, binder and additives. Application of heat during printing renders the microcapsule walls permeable to the dye resulting in color development upon reaction of the dye and color developer.
