Easy peelable adhesive and easy peelable adhesive material using the same

摘要

The present invention addresses the problem of providing an easily peelable adhesive agent which is adhesive at high temperatures and non-adhesive at low temperatures, and an easily peelable adhesive material using this adhesive agent. This problem can be solved by an easily peelable adhesive agent which has a melting point of 40°C or higher and has a glass transition temperature within the range of from 20°C to a temperature that is 20°C higher than the melting point of the easily peelable adhesive agent.
