摘要:
A heat-sensitive image recording material contains on a support material 1. at least one binder layer with a heat-sensitive imaging combination of an organic silver salt and an organic reducing agent for the organic silver salt, and 2. at least one binder layer or a sequence of binder layers with a heat-sensitive imaging combination of an acid-sensitive leuco dye and an acidically reacting compound which acts as a developer for the leuco dye, wherein the leuco dye and developer are in thermal interaction with each other either in different layers or separately from each other in the same layer, characterised in that a layer with a water- or alcohol-soluble polymer is arranged between the combination of organic silver salt and organic reducing agent for the organic silver salt, on the one hand, and the combination of leuco dye and acidically reacting compound, on the other. The image recording material is suitable for recording thermal images with elevated optical density, good grey scale reproduction and good stability.
摘要:
A coating device for coating a peripheral surface of a sleeve body with a coating formulation includes a vertical support column for supporting a sleeve body in a vertical position coaxial with a coating axis, a carriage slideable along the vertical support column, and an annular coating stage attached to the carriage and moveable therewith for containing the coating formulation and for coating a layer of the coating formulation onto the peripheral surface of the sleeve body during a sliding movement of the carriage along the vertical support column. The coating device includes an irradiation stage that is arranged to be moveable with the annular coating stage and to provide radiation to at least partially cure the layer of coating formulation onto the peripheral surface so as to prevent flow off of the coating formulation.

摘要:
According to the present invention there is provided a heat-sensitive non-ablatable wasteless imaging element for providing a lithographic printing plate, comprising on a support a top layer which is capable of forming by image-wise exposure image-wise hydrophobic and hydrophilic areas, characterized in that said imaging element contains an IR-dye capable of changing its optical density by exposure of the imaging element.
摘要:
A material is disclosed which is suitable for making a flexographic printing plate and comprises in the order given a base, a photopolymer layer and a photothermographic or thermographic recording layer which contains an organic silver salt. By image-wise exposing the recording layer, a photomask is obtained through which the photopolymer layer can be subsequently exposed. Using a suitable solvent, the (photo)thermographic recording layer can be removed and the unexposed areas of the photopolymer layer can be washed out simultaneously in a single development step. The relief image thus obtained can be used as a print master for flexographic printing.
摘要:
A method is disclosed for making on a transparent receiver material a continuous tone image, e.g. for medical diagnostic purposes, with an obtainable maximal transmission density in the visual region greater than 3.0, by means of ink jet. The method comprises ink-jetting combinations of at least one liquid black pigmented ink and at least one liquid grey ink to a transparent receiver comprising an ink receiving layer, a transparent support and a backing layer, said ink receiving layer comprising a N-containing polymer, preferably gelatin, as binder, and being substantially free of particles having an average size larger than 1 &mgr;m. Preferably the transparent receiver exhibits a haze value between 10 and 20%, determined according to standard test ASTM D 1003, due to the presence of a spacing agent in the backing layer.
