摘要：A process in which a photosensitive material containing an ester or an amide of a1,2-quinonediazidesulphonic or -carboxylic acid and a quaternary phosphoniumcompound as photosensitive compound is exposed through an image, then heated,exposed again over its entire surface after cooling and then developed with an aqueousalkaline developer. The process makes it possible to produce negative copies with amaterial which yields positive copies when processed normally.
