HEAT-SENSITIVE RECORDING METHOD, HEAT-SENSITIVE RECORDING MEDIUM USED FOR SAID METHOD AND PRODUCTION METHOD OF SAID MEDIUM

摘要

This invention provides a heat-sensitive recording medium comprising a thin metal film layer (8), heat-sensitive layers (6), (10) disposed in contact with the thin metal film layer and a contrast providing layer (4) disposed in contact with the heat-sensitive layers or with the thin metal film layer and having a visual contrast with respect to the thin metal film layer. When the heat-sensitive layers (6), (10) or the contrast providing layer (4) formed in contact with and prior to the formation of the thin metal film layer (8) is formed, fine particles are mixed into the heat-sensitive layer material or into the contrast providing layer material so as to form the heat-sensitive layer or contrast providing layer having a coarse surface, and the thin metal film layer is deposited on them by a thin film deposition method. In this manner a heat-sensitive recording medium having a thin metal film layer whose surface is coarsened can be produced. The heat-sensitive layers (6), (10) and the thin metal film layer (8) are heated in desired patterns to the heat-sensitive recording medium and the heated portion of the thin metal film layer is fused and is dispersed as fine particles into the heat-sensitive layers which are in contact with it. In this manner, heat-sensitive recording is effected by rupturing the thin metal film layer in the desired pattern.
