Typically, positive charges appear as electrostatic spots and negative charges appear as dendrites. Along with the improvement of the light sensitivity of the photographic emulsion, the improvement of the coating speed and the reduction of the environmental humidity, the probability of electrostatic spots is increased, and a large amount of products are scrapped when the probability is serious, so that great loss is caused. The RC highlight photographic paper is photographic paper which is made by coating film-coated photographic paper base paper on two sides through multiple layers, and the RC highlight photographic paper has the problems of large equipment investment, more coating times, more complex process and low yield, so that the problem of avoiding the loss of finished products caused by electrostatic action is needed to be solved at present.
