摘要:
A process for the production of a heat-sensitive recording material in which a color former causing a color formation reaction and a developer forming color on reaction with the color former are incorporated in a heat-sensitive recording layer, and at least one of the color former and the developer is contained in microcapsules having walls which are impermeable to both the color former and the developer at ordinary temperature but which becomes permeable to at least one of the color former and the developer on heating, where the heat-sensitive recording layer is coated on a support which is then subjected to surface treatment by passing it through a pressure applying apparatus comprising a metallic roll and an elastic roll in such a manner that the heat-sensitive recording layer is in contact with the metallic roll.

A heat-sensitive recording material is disclosed. The material comprises a support having provided on the same surface thereof microcapsules containing a basic colorless dye and an organic solvent, and a developer capable of reacting with the basic colorless dye to develop a color, the capsule walls of said microcapsules being impermeable to either of the basic colorless dye and the developer at room temperature but becoming permeable to the colorless dye and/or the developer upon application of heat. The organic solvent is a compound containing at least two benzene rings in the molecule thereof with a total number of at least one hetero atom selected from nitrogen, sulfur, oxygen and phosphorus atoms, if any, being less than 1/10 a total number of carbon atoms of the organic solvent. The material is excellent in preservability before and after recording and is excellent in heat-developability.

A heat-sensitive recording material is disclosed, comprising a support and heat-sensitive recording layer on the support, said layer containing (1) microcapsules containing a basic dye precursor and an organic solvent as the core thereof and (2) a developer capable of forming color on reacting with the basic dye precursor, wherein said microcapsules are produced by the use of a wall-forming substance comprising xylylene diisocyanate or an adduct thereof such that the microcapsule walls are impermeable to both the basic dye precursor and developer at room temperature, but at a temperature of a thermal head during a recording process, become permeable to at least one of the basic dye precursor and developer, thereby permitting formation of a colored image as a result of the reaction between the basic dye precursor and the developer. This material can retain its excellent recording ability for a long period of time; that is, it possesses excellent storage stability, and moreover can produce a recorded image of high storage stability.
