Metal patterns (,) can be provided on a glass substrate (,) in an electroless process by modifying the substrate with a silane layer (,), locally removing said layer with a laser or UV-ozone treatment and selectively nucleating the remaining silane layer in a polymer-stabilized Pd sol. Neither a photoresist nor organic solvents are used. The method is very suitable for the manufacture of the black matrix on a passive plate for an LCD, or on panels of other flat colour displays, such as flat cathode ray tubes.

Method of providing a metal pattern on glass in an electroless process

An X-ray examination apparatus (,), including an X-ray source (,) and an X-ray detector (,), is provided with an X-ray filter (,) which is arranged between the X-ray source and the X-ray detector. The X-ray filter (,) includes a plurality of filter elements (,) whose X-ray absorptivity can be adjusted by adjustment of a quantity of X-ray absorbing liquid (,) within the individual filter elements; a first end of individual filter elements communicates with the X-ray absorbing liquid whereas a second end communicates with an X-ray transparent liquid (,). The X-ray filter is preferably provided with a pressure control system for independent control of the liquid pressure in individual row ducts (,) and individual column ducts (,). Individual filter elements are preferably provided with a piston for separating the X-ray absorbing liquid from the X-ray transparent liquid.
