Abstract
It is an object of the present invention to provide a composition for an acoustically matching layer, having sufficient mechanical strength to allow itself to be easily formed, and capable of giving an acoustically matching layer highly stable in characteristics over extended periods even under high temperature and high humidity conditions. The present invention provides a composition containing a carbodiimide resin for an acoustically matching layer, where the composition may further contain inorganic hollow bodies or inorganic hollow bodies and another reactive resin; a process for producing a formed article of an acoustically matching layer by curing and forming under heating the composition in a mold for the acoustically matching layer; and an ultrasonic transducer using the same composition and ultrasonic transducer using the same formed article.
