Zusammenfassung:	PURPOSE:To obtain diazo sensitized paper having excellent preserbility, bringing no yellowing even when stored for a long period. CONSTITUTION:The diazo sensitized paper is produced by forming a diazo sensitized layer directly on a supporting body or through an under coating layer, and at least either of the diazo sensitized layer and the under coating layer contains silica and polyamide resin or its deriv. with the solid weight ratio of 2:1 to 30:1. By adding a polyamide resin or its deriv. into the diazo sensitized layer or the under coating layer containing silica, the oxidants adsorption place of silica is sealed. Thus diazo sensitized layer shows good preserbility without showing color is not turned yellow even for long-period preservation.
