A cartridge includes: a cartridge case; a first supply portion including a heat-sensitive medium; and a second supply portion including an adhesive medium. The heat-sensitive medium includes a base material, a plurality of heat-sensitive layers, and at least one heat-insulating layer in a stacked state. The heat-sensitive layers include: a first heat-sensitive layer for producing a first color when heated above a first temperature; and a second heat-sensitive layer for producing a second color when heated above a second temperature higher than the first temperature. The cartridge case includes: an opening for exposing the heat-sensitive medium; and a guide part positioned downstream of the opening in a conveying direction of the heat-sensitive medium for guiding the heat-sensitive medium and the adhesive medium bonded to a surface of the heat-sensitive medium opposite the base material with respect to the plurality of heat-sensitive layers.

[PROBLEM] To provide a packaging and a display material which permit printing in distinct fashion by a laser, and which are of high transparency. [SOLUTION MEANS] A display material having at least one layer permitting printing as a result of laser irradiation, the display material being such that the printing occurs due to change in color caused by the laser irradiation in at least one region of said layer; when a digital microscope is used to carry out cross-sectional observation of said printed region and a nonprinted region, a significant difference in at least any one of RGB values indicating color elements is observed; and thickness of said printed region is not less than 5 m but not greater than 200 m.

A thermal sensitive media for use with labeling or identification methods is disclosed. The thermal sensitive media comprises a media layer and a thermally sensitive record layer formed upon at least one surface of the media layer. The thermally sensitive record layer forms a visually discernable colored image in response to heat. However, the colored image is subject to degradation as a result of exposure to ultraviolet radiation within a known photodegradative wavelength range. An ultraviolet protective coating layer may then disposed over the thermally sensitive record layer. A lamination layer is positioned internal to the media layer and comprises a matrix of micro heating elements driven by radio frequency (RF) power. The matrix of micro heating elements are arranged in a pin array to energize the micro heating elements within the laminated media structure to create a simple numeric image.

A recording medium capable of reducing a color gamut change is provided. The recording medium includes a plurality of coloring layers and at least one diffusion reduction layer. Each of the coloring layers includes a coloring compound that is electron-donative, a developer that is electron-acceptive, and matrix resin. The diffusion reduction layer is provided between the coloring layers adjacent to each other. The diffusion reduction layer is capable of reducing diffusion of the coloring compound between the coloring layers adjacent to each other during heating of the recording medium.

The present invention relates to a thermal transfer film comprising: a base layer; and a light-to-heat conversion layer which is laminated on top of the base layer and includes a first layer laminated on top of the base layer and a second layer laminated on top of the first layer in the thickness direction, wherein light-to-heat conversion materials are more omnipresent in the first layer than the second layer.
