Development of Inorganic Black Pigment "NITRBLACK® UB-2
- More than 50% improvement of UV transmittance by further development of the world's first technology -

(1cm of thickness)

Mitsubishi Materials Corporation and its consolidated subsidiary, Mitsubishi Materials Electronic Chemicals Corporation, have developed NITRBLACK®️ UB-2, which improved the transmittance of ultraviolet rays ("UV") more than 50% compared to conventional inorganic black pigments.

Black peripheral materials are used as light shielding materials in liquid crystal displays, optical sensors, etc., and light-curing technology that enables low-temperature processing is utilized for their formation. However, with conventional technologies, black pigments absorb light in the UV range necessary for curing, resulting in insufficient curing.

In 2017, we developed the world's first inorganic black pigment with high UV transparency, and now, by further developing this technology, we have succeeded in developing "NITRBLACK®️ UB-2" with improved transparency in the UV region by more than 50%. This new product reduces the UV irradiation time for resin curing to less than a quarter of the conventional UV irradiation time (according to our test results), and enables curing of thicker resin films.

It is expected to be used in a wider range of applications in the future, and is also expected to improve energy efficiency used in customers and reduce greenhouse gas emissions.
