What is REXWIN ™?
REXWIN ™ is a functional paste that leverages artience group 's core technologies such as 'ink design' and 'dispersion' cultivated over a long history to achieve light shielding, near-infrared transmission, low reflection, refractive index control, and adhesion required in the field of optical electronics.
TOYO INK collectively refers to the range of products with various functional features as the REXWIN ™ Series.
REXWIN ™ lineup
Among the REXWIN ™ series, we introduce products with strengths in optical control, organized by function.
Optically controlled black ink
low reflective black ink
SS MATT911 Series
This black ink achieves a reflectance of less than 1%. It has excellent low reflectivity according to the reflectance measurement angle, enabling more precise control of ghosting and flare. By blocking light from the lens and suppressing stray light, it contributes to improved image quality.
High light-blocking black ink
SV SSLS Series
This black ink achieves high light-blocking performance with a thin film. It contributes to suppressing internal reflections and stray light within prism lenses.
Infrared Transmission Black Ink
SV SSIPBLACK Series
This black ink combines high blocking in the visible light range with high transmittance in the near-infrared range. It enables high-precision wavelength control in the near-infrared region in infrared cameras and sensors.

Optical adhesives
UV-curable adhesives REXWIN ™ UA series
High-Reflectivity, Light-Diffusing White Ink
This is a white ink with a reflectivity of 95%. It enables efficient use of light through reflectance control and uniform diffusion in display backlight units and LED mounting boards.
