Abstract

The objective of this project was to study the practical parameters that interact in the formation of the final effect of commercially used OBA and to simultaneously look for technical solutions that would be different from those used today. In this work the behaviour of a commercial OBA used in paper industry was experimentally studied and the effect was compared with that of an inorganic blue luminescent powder on paper. An approach for a new synthetic inorganic blue luminescent OBA powder was successfully studied. The bioluminescent potential in connection with paper was studied in the light of published data and preliminary tests.
