Ultraviolet and Visible Absorbing Dyes

Absorbing Dyes for Solvent Systems

QCR Solutions’ Ultraviolet (UV) and Visible (Vis) Dyes are available in a wide spectral range. We have a large library of standard UV-VIS dyes ranging from narrow notch to broad band absorbers that can attenuate selective wavelength regions. These UV-VIS dyes can be used singly or in combinations to create custom spectral filters for multiple applications.

Our Ultraviolet (UV) and Visible (Vis) Dyes can be incorporated into coatings, inks, solutions and plastics. They have found uses in Light Filters (narrow or broad band), Anti-halation, Laser applications, Ultraviolet Visible Spectroscopy, Digital Printing applications like Computer to Plate (CTP) and many more applications.

Below is a representative list of our Ultraviolet and Visible absorbing Dyes. Also available is our helpful guide on how to calculate your absorbing dye’s starting concentration: Concentration Calculation Worksheet | 2018 | QCR Solutions Corp

If you can not find the right absorbing dye from the above list. Just let us know your application’s specification and we will custom synthesize the perfect absorbing dye (UV, Visible, or NIR) for your project:

Wavelength required to be absorbed, filtered, or blocked
Wavelength required for high transparency
Matrix Compatibility (Solvent, Plastic, or other)
Process Conditions
Lightfastness
Thermal Stability

Let us design an absorbing dye for your next NIR light filter, Security Coating or other application. We look forward to working with you.
