Kodak Professional Endura papers are multi-layer color papers processed in RA4 chemistry that provide state-of-the-art image stability, thanks to imaging science advances from Kodak. These technologies offer image stability of more than 100 years before noticeable fading occurs in the typical home display, and more than 200 years before fading occurs in dark storage conditions.

In 1997, Kodak patented 2,5-diacylaminophenol couplers, which provided excellent thermal stability combined with desirable color hue. These couplers were incorporated into the Kodak photographic paper in 1999. These couplers have been significantly improved for use in Kodak Professional’s  Endura family of papers. The papers based on these couplers all have thermal stability that is significantly better than any other color photographic paper.

This exceptional image stability gives us a strong advantage with customers particularly wedding, portrait or fine art clients who want to keep their photographs as heirlooms for generations.
