Claims19
A reversible recording medium comprising:
- a recording layer including a leuco pigment as a coloring compound;
- and
- a first barrier film that is provided on one surface and a side surface of the recording layer and suppresses mixing of at least one of water or oxygen with the recording layer,
- wherein
- the first barrier film is continuously provided from the one surface to another surface of the recording layer that is opposed to the one surface, and
- an end part of the first barrier film is sealed by a sealant to an outer peripheral part of the another surface.
A reversible recording medium comprising:
- a recording layer including a leuco pigment as a coloring compound;
- and
- a first barrier film that is provided on one surface and a side surface of the recording layer and suppresses mixing of at least one of water or oxygen, wherein
- the recording layer has a rectangular shape, and
- four sides of the first barrier film are sealed by a sealant on diagonal lines of another surface of the recording layer that is opposed to the one surface.
An exterior member comprising a reversible recording medium on at least one surface of a support base,
- the reversible recording medium comprising:
- a recording layer including a leuco pigment as a coloring compound;
- and
- a first barrier film that is provided on one surface and a side surface of the recording layer and suppresses mixing of at least one of water or oxygen with the recording layer,
- wherein
- the first barrier film is continuously provided from the one surface to another surface of the recording layer that is opposed to the one surface, and
- an end part of the first barrier film is sealed by a sealant to an outer peripheral part of the another surface.
An exterior member comprising a reversible recording medium on at least one surface of a support base,
- the reversible recording medium comprising:
- a recording layer including a leuco pigment as a coloring compound;
- and
- a first barrier film that is provided on one surface and a side surface of the recording layer and suppresses mixing of at least one of water or oxygen with the recording layer,
- wherein
- the recording layer has a rectangular shape, and
- four sides of the first barrier film are sealed by a sealant on diagonal lines of another surface of the recording layer that is opposed to the one surface.
