PROBLEM TO BE SOLVED: To mainly provide a campaign label for heated sales container capable of positively hiding information code on it. SOLUTION: A campaign label 1 for a heated sales container has a heat shrinking transparent base film 2. One surface of the base film 2 is provided with a pattern printing layer 3. An information code layer 4 formed by reversible thermosensitive discoloration ink the color of which disappears at 45°C or above is printed on the pattern printing layer 3. In case that the label is attached to the container for tea which is heated up to 40°C or above at a store and sold, for example, the information code layer already shows its discolored state, so that it is possible to hide the information code positively without damaging the label design through the information code printed on its rear surface. In turn, when a customer completely drinks the content in the container and its temperature becomes a room temperature, the information code shows its own color, so that when the label is peeled off, the customer can easily read the information code on the rear surface.
