Abstract
A one-component system polyurethane gel and a coupler for ultrasonic diagnostic probes comprising the same are disclosed. The gel is obtained by reacting a polyol having a room temperature liquid alkylene oxide chain and/or a polyurethane polyol prepolymer having a room temperature liquid alkylene oxide chain with a polyurethane polyisocyanate prepolymer having a room temperature liquid alkylene oxide chain. The gel causes no bleeding or evaporation of a dispersion medium and is therefore excellent in safety to the human body and preservation stability.
