Abstract
A recording medium according to an embodiment of the present disclosure includes: a recording layer including a leuco dye as a coloring compound; a first barrier film that is provided on each of one surface and another surface opposed to the one surface of the recording layer, and suppresses intrusion of moisture, oxygen, or both; and a second barrier film having chemical resistance and provided on a side surface of the recording layer continuously at least from a peripheral part of the one surface to a peripheral part of the other surface of the recording layer.
Claims24
A recording medium comprising:
- a recording layer including a leuco dye as a coloring compound;
- a first barrier film that is provided on each of one surface and another surface opposed to the one surface of the recording layer, and suppresses intrusion of moisture, oxygen, or both with the recording layer;
- and
- a second barrier film having chemical resistance and provided on a side surface of the recording layer continuously at least from a peripheral part of the one surface to a peripheral part of the another surface of the recording layer,
- wherein the side surface of the recording layer is inclined.
An exterior member comprising a support base and at least a recording medium on the support base, the recording medium including:
- a recording layer including a leuco dye as a coloring compound;
- a first barrier film that is provided on each of one surface and another surface opposed to the one surface of the recording layer, and suppresses intrusion of moisture, oxygen, or both with the recording layer;
- and
- second barrier film having chemical resistance and provided on a side surface of the recording layer continuously at least from a peripheral part of the one surface to a peripheral part of the another surface of the recording layer,
- wherein the side surface of the recording layer is inclined.
A recording medium comprising:
- a recording layer including a leuco dye as a coloring compound;
- a first barrier film that is provided on each of one surface and another surface opposed to the one surface of the recording layer, and suppresses intrusion of moisture, oxygen, or both with the recording layer;
- and
- a second barrier film having chemical resistance and provided on a side surface of the recording layer continuously at least from a peripheral part of the one surface to a peripheral part of the another surface of the recording layer,
- wherein a surface of the second barrier film provided on the side surface of the recording layer includes a curved surface.
A recording medium comprising:
- a recording layer including a leuco dye as a coloring compound;
- a first barrier film that is provided on each of one surface and another surface opposed to the one surface of the recording layer, and suppresses intrusion of moisture, oxygen, or both with the recording layer;
- and
- a second barrier film having chemical resistance and provided on a side surface of the recording layer continuously at least from a peripheral part of the one surface to a peripheral part of the another surface of the recording layer,
- wherein the second barrier film is formed from an ultraviolet curable resin,
- wherein the ultraviolet curable resin comprises an organic-inorganic hybrid material,
- wherein the organic-inorganic hybrid material has a silsesquioxane skeleton represented by a composition formula [(RSiO1.5)n], and
- wherein R is an organic group.
