| abstract |
The invention relates to both highly pigmented and transparent coating products which can be polymerized photochemically by irradiation with emission in the near ultraviolet and in the visible, possibly followed by additional irradiation in she infrared and/or in the ultraviolet, and consist of homogeneous dispersions of ethylenically unsaturated polymer substances, and photocatalysts based on compounds of metals of group IV A and of groups I B to VII B and VIII of the periodic table, preferably in the presence of photoinitiators chosen from derivatives of thioxanthone, acetophenone, benzophenone, benzoin, ketoxime and acylphosphine oxide, and either containing or not containing pigments and/or fillers. |
