摘要： Negative-working imageable elements are prepared with radiation-sensitive imageable layers that contain surface-modified silica particles such as fumed silica particles and sol-gel silica particles, that are present in an amount of from about 1 to about 40 weight %, have an average particle size of from about 1 to about 500 nm, have surface hydroxy groups, and have a carbon content of from about 0.5 to about 15 weight % that is derived from surface hydrophobic groups having 1 to 30 carbon atoms. The presence of the surface-modified silica particles provides improved abrasion resistance, reduced tackiness, and various other desired properties.

摘要： Radiation-sensitive compositions and imageable elements include a polymeric or non-polymeric component in an imageable layer, which component includes 1H-tetrazole groups. The non-polymeric components can be radically polymerizable compounds. The polymeric components can have 1H-tetrazole groups that are pendant to the backbone. The use of such components in negative- or positive-working imageable elements provides high photospeed and improved developability for providing imaged and developed elements, such as lithographic printing plates that show improved chemical resistance and run length.

摘要： An endoscope, exoscope or microscope, including an optical fibre bundle for transmitting light from the proximal end to the distal end, the optical fibre bundle showing a contiguous bundle at the proximal end and a plurality of partial bundles or else individual fibres at the distal end. Furthermore, it shows a light source for coupling light into the one proximal end of the optical fibre bundle and including a multiplicity of individually actuatable individual-light sources arranged in an array-like manner, and a control unit for actuating the individual-light sources using an assignment function which represents the assignment of a proximal fibre end to a partial bundle. Here, the proximal ends of the fibres which are assigned to one partial bundle are arranged on a surface in such a way that proximal ends of fibres assigned to a different partial bundle are arranged therebetween.

摘要： A lithographic printing plate precursor comprises an imagable layer comprising a free radically polymerizable component, an initiator composition capable of generating free radicals upon exposure to imaging infrared radiation, an infrared radiation absorbing dye comprising an infrared radiation absorbing cation and a counter anion, and a polymeric binder. The salt formed between the infrared radiation absorbing cation and a tetraphenyl borate has solubility in 2-methoxy propanol at 20° C. that is greater than or equal to 3.5 g/l. The use of these infrared radiation absorbing dyes in the imagable layers provides a reduced tendency of these dyes to crystallize in the presence of tetraaryl borate counter anions.

摘要： An observation instrument has a hollow shaft in whose distal end region there is arranged an optoelectronic imaging system which has on the image entrance side a distal deflection prism whose deflection faces lead an image into an optical lens system which images the image onto the image plane of an image sensor arranged proximally from the lens system, the image sensor having an active region which is situated asymmetrically relative to the outer contour of the image sensor. A first plane, which is defined by the main beam and a first orthogonal on the image plane of the image sensor, and a second plane, which is defined by the main beam and a second orthogonal on the deflection faces of the distal deflection prism, being rotated relative to one another about the main beam in such a way that it is possible to produce a sight cone which is symmetrical relative to a midplane of the hollow shaft and whose image area is situated fully in the active region of the image sensor.

摘要： Both positive-working and negative-working imageable element can have a radiation-sensitive imageable layer that has at least one pigment colorant that does not change color when heated, and at least one dye that can change color when heated. The dye is soluble in the solvent or mixture of solvents used to coat the radiation-sensitive imageable layer on a substrate and the pigment colorant is not. This combination of pigment colorant and dye provide excellent image contrast after imaging, development, and postbaking. The pigment colorant and the dye independently have a maximum absorption of from about 480 to about 700 nm.
