Abstract: Photographic images are produced by imagewise decomposition of addition compounds of hydrogen peroxide with organic compounds, the image being made visible, either physically by developing the gas bubbles formed during decomposition, or chemically by using the oxygen formed during decomposition for a color-forming reaction.
Abstract translation: 通过使有机化合物的加成化合物的图像分解，使图像变得可见，或者通过显影分解期间形成的气泡，或通过使用在分解期间形成的形成氧化反应形成的氧来化学地生成照相图像。

Abstract: A process for the production of positive photographic images comprising the steps of imagewise exposing a light-sensitive silver salt emulsion layer, photographically developing to form a negative silver image in the exposed areas, treating the exposed and developed layer with a peroxide compound, the peroxide compound is left to act on the layer until it has been decomposed at the negative silver image, and forming a positive image by decomposition of the undercomposed peroxide compound in the unexposed areas of the layer.
