Abstract
Abstract Process for modifying tacky surfaces, e.g., tacky layer on a photograph or other photochemically produced record, which comprises applying an admixture of particulate material and carrier particles and removing the excess particulate material and carrier particles. The ratio of average particle diameter of the carrier particles to average particle diameter of the particulate material is greater than 2 and the weight ratio of particulate material to carrier particles is less than 1. The degree of surface modification, e.g., light reflectivity, etc., can be controlled by the process.
