Abstract

Heat curable cationically polymerizable organic materials, such as epoxy resins, are described based on the use of an aromatic onium salt initiator which can be used in combination with a reducing agent. The heat curable compositions can be used in a variety of applications, such as coating compounds, photoresists, etc.
