Anthrone derivatives having hydroxy, ether or hydrocarbyl groups in 10-position, for example 10,10-dimethoxyanthrone, are excellent photoinitiators for the UV-curing of unsaturated systems. Preferable systems are monomeric or oligomeric acrylates and their mixtures. The systems may be used in thin layers as for instance for coatings or printing inks. |
