| Résumé : |
How the availability of new photoinitiators is resulting in the more efficient curings of inks ?
Today, UV-curable systems are well established in numerous graphic art applications such as inks and overprint varnishes. In addition, promising new application areas, for instance UV inkjet, were developed in the recent years. The availability of efficient photoinitiators is essential for the progress of UV technology, since reactivity directly influences speed and stability if the production process.
High photoinitiator reactivity is vital for a high conversion degree of the binder molecules at a very high cure rates ; this in turn directly influences the resistance properties and the migration behaviour of the cured inks and varnishes. Low volatility, low odour and migration are required to meet increasingly stringent legal restrictions, in particular for food packaging. |
