In a survey the development of epoxy resin systems is described. During the past years countless formulations based on known structures were used, but only a relative small number of new epoxies and curing agents were investigated and only very few new compounds came on the market. A choice of these products will be discussed, also new latent accelerators and curing agents. By improvement of technical processes purer epoxies can be offered and toxicological risks could be strongly reduced. Especially new results in the fast growing field of photocrosslinking will be described. Besides iodonium, sulfonium and phosphonium compounds new arene iron salts and their behaviour will be presented. Generally, the trend in the epoxy field is to better heat resistant structures for new formulations in the field of adhesives and fibre‐reinforced materials, and to new photocrosslinking systems.
