Abstract

PURPOSE:To prevent the ground part from yellowing after copying and to well maintain the contrast of the image by adding a specified mercapto compound to the precoat layer or the photsensitive layer of a diazo copying material. CONSTITUTION:On the support of a 1- or 2-component type diazo copying material a precoat layer is formed as required. To the precoat layer and/or the diazo photosensitive layer is added >=1 kinds of mercapto compound having OH, COOH or alkali metallic salt of COOH. The amount of the added mercapto compound is about 0.01-5mol to 1mol diazo compound.
