HOT MELTING ADHESIVES, METHODS OF PRODUCING THEM, AND COATING METHODS

Abstract

An objective is to provide an antibacterial hot-melt adhesive that does not undergo phase separation even when heated for a long time, has high safety for the human body, and is able to maintain stable antibacterial properties even when heated for a long time. The objective is achieved by a hot-melt adhesive that includes: a base polymer; a adhesive; and an antibacterial agent that has a paraben structure and that has a 10% weight loss temperature of not lower than 200°C in thermogravimetric measurement, the hot-melt adhesive having a melting viscosity at 140°C of not greater than 20,000 mPa·s.
