Resin coated papers, adopted for color prints in 1968, have been observed to yellow, crack, and turn brown around the edges, but color photographs on RC paper outlast earlier color prints. Black and white prints on RC paper do not last as long as on uncoated paper. In this paper, fading of black and white prints on RC paper is tested by monitoring image density changes. High heat and humidity conditions were simulated. Greater image stability was found on fiber-based papers. Hydrogen sulfide gas also produced image changes in an accelerated aging experiment, particularly in the RC papers. Change of developer affects image stability, but further testing is required. For duplication and long-term storage, fiber-based paper is recommended.
