Developmental Water-Based Polyurethane Paints

We are developing water-based polyurethane paints with various dyes,

One was subjected to 1.5 hrs. of very close-range long wavelength UV with 1/2 the area exposed to UV and the other half covererd.

We found no fading occured in this time frame.

Below is a swatch of three various commerical dyes with the water-based polyurethane binder on bristol paper:

Water-based polyurethane emulsion is more expensive than the acrylics , but the former is bio-degradable.
