    摘要: A method of manufacturing a diazo copying material for use in preparing a secondary original, which comprises coating a water-dispersible precoating liquid comprising a porous powder, a binding agent and an anionic surface active agent having the following general formula on a transparent or translucent support and drying thereafter, and subsequently coating a photosensitive liquid consisting essentially of a photosensitive diazonium salt on the precoated surface of said support and drying thereafter.General formula: ##STR1## [wherein m represents Na or K, and R represents alkyl radical having 1 - 20 carbon atoms]

    摘要: A one-component or binary type diazo copying element comprises a substrate, a pre-coat layer overlying the substrate, said pre-coat layer being consisted essentially of fine particle silica and a specific copolymer having a glass transition temperature in the range of -20.degree. C. to 50.degree. C., and a diazo photosensitive layer overlying the pre-coat layer.
