Abstract
In providing an adhesive connection or a seal using a thermoplastic adhesive for securing materials together, a thermochrome dye is added to the thermoplastic adhesive so that it provides a color change in the temperature range between the temperature where a satisfactory moistening effect is achieved and the temperature where the satisfactory moistening effect is no longer present.
