  • Photoreversible adhesive agent
    Patent number: 10767088
    Abstract: When conventional photo-reactive compounds are to be liquefied with the application of light, liquefaction thereof is time-consuming due to poor sensitivity to ultraviolet light. In the case of conventional photo-reactive compounds, disadvantageously, light does not penetrate through layers to be adhered to each other when such layers are thick. Thus, peeling is not sufficiently performed. Accordingly, it is an object of the present invention to overcome such drawbacks of conventional photo-reactive compounds and provide a photo-reactive adhesive agent exhibiting high sensitivity to light for fluidization and capable of easy peeling.
