A direct pigment photographic printing process and composition based on a two-step coating process comprising a first coating applied to a sealed substrate containing between 2 to 8 and 8 to 2 weight parts of gum arabic to gelatin, and then applying a second top coating containing preferred ratios of gum arabic to gelatin. The process is based on heating the first and second coating compositions sufficiently above about 105 DEG F. prior to application to the substrate to assure homogeneous mixtures of each coating at the time of application.
