Verfahren zur Herstellung eines photographischen Papieres mit einer Rückseitenschicht, die kolloidale, anorganische Oxidteilchen, ein Antistatikum und ein filmbildendes Acrylatbindemittel enthält

摘要

The present invention is a polyolefin resin coated paper base having a backing layer. The backing layer is formed by coating and subsequent drying of a coating composition having dispersed therein colloidal inorganic oxide particles, an antistatic agent and a film forming binder. The film forming binder is a carboxylic acid containing vinyl polymer or copolymer having a glass transition temperature greater than 25 DEG C and an acid number of from 30 to 260 wherein the carboxylic acid containing vinyl polymer or copolymer is reacted with ammonia or amine so that the coating composition has a pH of from 7 to 10.
