379 is especially suitable for pigmented UV curable
systems, photoresists and printing plates. Due to its excellent solubility
(compared to 369) it is easy to incorporate into almost all
formulations
379 may be used after adequate testing alone or in
combination with suitable co-initiators, such as 184,
651 or ITX, for UV curable inks, varnishes and
resist formulations for applications on paper, metal and plastic
materials. Its red-shifted absorption spectrum makes it especially
suitable for UV curable inks.
Applications in graphic arts (e.g. offset and screen inks, printing plates,
etc.) and in the electronics industry (e.g. photoresists for the production
of color filters or other display applications and for solder resists, etc.)
are of particular interest.
Compared to E 369, 379 differentiates especially
due to its substantially improved solubility which allows its use for
applications in which 369 is at the solubility limit or couldn’t
be used at all due to the limited solubility.
The amount of 379 required for optimum performance
should be determined in trials covering a concentration range
