Definitions
- the invention relates to new ketone derivatives and their use as photoinitiators for the photopolymerization of ethylenically unsaturated compounds or systems containing them.
- the invention relates to the use of these compounds as photoinitiators for the photo polymerization of ethylenically unsaturated compounds in aqueous systems and also aqueous photopolymerizable systems containing such ketone derivatives.
- the invention further relates to photopolymerization processes for the production of aqueous polymer solutions or polymer dispersions and for the production of water-soluble or hydrophilic polymers in which such ketones are used as photoinitiators.
- the invention relates generally to the use of these compounds as photoinitiators, that is to say also in non-aqueous systems, and to corresponding photopolymerizable systems.
- Photochemically induced polymerization reactions have gained great importance in technology, especially when it comes to rapid hardening of thin layers, such as, for example, the hardening of lacquer and resin coatings on paper, metal and plastic or in the Drying of printing inks, since these processes are characterized by raw material and energy savings and a lower environmental impact compared to conventional methods for printing and coating objects.
- photoinitiators Since, as a rule, none of the reactants in the reactions mentioned is able to absorb the photochemically effective radiation to a sufficient extent, so-called photoinitiators must be added, which do not participate in the desired reaction, but are capable of irradiating light or absorb UV rays, transfer the energy absorbed to one of the reaction partners and thus form active starter radicals, which in turn trigger the photopolymerization.
- Essential criteria for the selection of such initiators include the type of reactions to be carried out, the ratio of the absorption spectrum of the initiator to the spectral energy distribution of the available radiation source, the solubility of the initiator in the reaction mixture, the dark storage stability of the reaction system mixed with the initiator and the influencing of the end products by residues of the initiator remaining therein and / or the products resulting therefrom during the photochemical reaction. Especially the speed the reaction strongly depends on the initiator used. There has therefore been no lack of attempts to look for new initiators which show an increased reactivity in their ability to initiate the photopolymerization of ethylenically unsaturated compounds or the curing of photopolymerizable systems.

These systems can either contain only a certain monomer or also mixtures of copolymerizable monomers of different types. All such ethylenically unsaturated compounds are possible which are sufficiently water-soluble or can be emulsified without problems in water.
