Abstract
Abstract A heat-sensitive recording material and a recording method are disclosed, wherein the heat-sensitive recording material comprises a support having formed thereon plural heat-coloring elements each comprising a diazo compound and a coupling component capable of causing heat-coloring, the heat-coloring elements coloring in two or more different hues, and the coloring property in each heat-coloring element being capable of being stopped by the action of different radiations, and the recording method comprises first heat-coloring a heat-coloring element of the heat-sensitive recording material, stopping the heat-coloring property of the uncolored portions of the first heat-coloring element by radiation, and then heat-coloring another heat-coloring element; wherein the recording method comprises applying two or more heat-coloring procedures and one or more irradiations of radiation to form recorded images composed of two or more colors on the same sheet.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
121 words
A recording method comprising (1) heat-coloring a first heat-coloring element of a heat-sensitive recording material comprising a support having formed thereon plural heat-coloring elements coloring in two or more different hues, each element comprising a diazo compound and a coupling component causing heat coloring, and the coloring process of each heat-coloring element being able to be stopped by the action of different radiation, (2) stopping the heat-coloring property of the uncolored portions of the first heat-coloring element by radiation, and then (3) heat-coloring another of said heat-coloring elements,; whereby said heat-coloring procedure is conducted at least 2 times and said radiation is conducted at least 1 time to form recorded images composed of two or more colors on the same sheet.
Claim 2
Dependent Claim
121 words
A recording method comprising (1) heat-coloring a first heat-coloring element of a heat-sensitive recording material comprising a support having formed thereon plural heat-coloring elements coloring in two or more different hues, each element comprising a diazo compound and a coupling component causing heat coloring, and the coloring process of each heat-coloring element being able to be stopped by the action of different radiation, (2) stopping the heat-coloring property of the uncolored portions of the first heat-coloring element by radiation, and then (3) heat-coloring another of said heat-coloring elements,; whereby said heat-coloring procedure is conducted at least 2 times and said radiation is conducted at least 1 time to form recorded images composed of two or more colors on the same sheet.
Claim 3
Dependent Claim
50 words
A recording method as in claim 1, wherein said first heat-coloring element is colored at the lowest temperature and is heat-colored, and after stopping the heat-coloring property of the uncolored portions of said first heat-coloring element by radiation, another heat-coloring element which is colored at a higher temperature is heat-colored.
Claim 4
Dependent Claim
45 words
A recording method as in claim 1, wherein a heat-coloring element is first heat-colored, and after stopping the heat-coloring property of the uncolored portions of the heat-coloring element by radiation, another heat-coloring element is heat-colored at substantially the same temperature as the initial coloring temperature.
Claim 5
Dependent Claim
15 words
