    摘要： The invention relates to a recording material having a substrate and a negative-working, radiation-sensitive layer which contains a diazonium salt, at least one film-forming, polymeric binder and organic colored pigments, on the surface of which an organic polymeric dispersant has been adsorbed and which are additionally dispersed in an organic polymeric binder which does not permanently combine with the pigments chemically or physically. The dispersant generally has groups, in particular primary, secondary or tertiary amino groups or derivatives thereof, which act as anchor groups on the colored pigment particles. The pigments themselves are preferably phthalocyanine pigments. As a result of the predispersing, aggregation of the pigment particles is effectively prevented so that uniform coloration of the radiation-sensitive layer is achieved. During development of the imagewise exposed recording materials, the colored pigment particles form virtually no insoluble precipitates. In the prepared printing plates, the printing parts are distinguished from the substrate material through being clearly visible and having high contrast.

    摘要： The present invention relates to a recording material having a substrate and a negative-working, radiation-sensitive layer which contains a diazonium salt, metal-free colored pigments dispersed in an organic polymeric binder, transparent spacer pigments having a pore volume of more than 1.0 ml/g and a polymeric binder. The predispersal of the colored pigments is achieved by milling with an organic polymeric binder containing hydroxyl groups, some or all of which have been reacted with a di- or polycarboxylic anhydride so that the binder has an acid number of from 20 to 200. Printing plates in which the printing parts have a clearly visible contrast relative to the substrate can be produced from the recording material.

    摘要： Disclosed are a safe slurry photosensitive composition superior in image formation capabilities such as resolution and sensitivity and containing no harmful compound, and a safe water-soluble photosensitive composition capable of being dissolved in water without using any organic solvent while maintaining a sufficient sensitivity as a resist and containing no harmful substance. The slurry photosensitive composition contains a compound which generates an acid when irradiated with light or ionizing radiation, at least one type of a resin with acid-crosslinkability or acid-decomposability, and a powder. Various devices can be manufactured by forming a layer of this photosensitive composition on a substrate, exposing the layer to light in accordance with a desired pattern, and heating the layer. The water-soluble photosensitive composition contains a compound which generates an acid when irradiated with light or ionizing radiation, and an acetal resin. This water-soluble photosensitive composition is coated on a substrate and irradiated with light or ionizing radiation in accordance with a desired pattern. The resultant substrate is chemically amplified by heating and developed with water. This makes it possible to safely form a pattern without using any ventilator.
