An in-mold transfer film includes a release layer, a scent-emitting hard layer, a color-changing print layer and an adhesive layer formed sequentially in one direction on one side of a base layer, wherein the scent-emitting hard layer includes aromatic microcapsules, and the color-changing print layer changes its color according to the temperature. An method for manufacturing an in-mold transfer film includes the following steps: forming a release layer on one side of a base layer; forming a scent-emitting hard layer on an upper surface of the release layer; forming a print primer layer on an upper surface of the scent-emitting hard layer; forming a color-changing print layer formed on an upper surface of the print primer layer; forming an adhesive primer layer on an upper surface of the color-changing print layer; and forming an adhesive layer on an upper surface of the adhesive primer layer.

Provided are a label, a top layer material formed on a printing medium, an information-bearing medium, a solid fuel and a wristband clip having the function of absorbing carbon dioxide, and carbon dioxide reduction methods using the same. Provided are labels 101, 120, 130 and 140, top layer materials formed on a printing medium 201, 246 and 266, information-bearing media 301, 330, 350 and 360, a solid fuel 401, and a wristband clip 510, to which a new carbon dioxide absorbent is added. Provided are also carbon dioxide reduction methods of absorbing carbon dioxide by burning the same.

Direct thermal inks with heat retention are disclosed herein. An example direct thermal ink includes a thermal printable media, including a substrate, and a composite including a thermochromic material and a latent heat material; wherein the composite is coupled to the substrate and a color state of the thermochromic material changes responsive to the thermochromic material exceeding a predetermined temperature threshold; wherein the latent heat material melts responsive to an applied heat on the thermal printable media during a thermal printing process and, after the applied heat ceases, to release a stored portion of the applied heat as the latent heat material re-solidifies such that the composite remains in excess of the predetermined temperature threshold thereby increasing an amount of change in the color state of the thermochromic material in response to the applied heat during the thermal printing process.
