Abstract: A security card is disclosed which comprises a laminate of a flexible glass layer and a support, characterised in that the glass layer has a thickness of not more than 350 &mgr;m. The thin glass layer has sufficient flexibility to allow substantial bending of the card without causing breakage of the glass. In addition, the glass layer acts as a security feature because delamination in order to falsify information stored in the card is very difficult without breaking the glass. The glass is also an efficient barrier layer protecting the information stored in the card from mechanical damage and from degradation due to permeation of gases such as oxygen or water vapour.

Abstract: According to the present invention a data card is provided which comprises a heat-mode laser recording medium on a support and wherein said laser recorder medium is covered by a thin flexible glass layer. The data card has a higher mechanical strength, an improved shelf-life and offers better security with regard to counterfeiting. The heat-mode laser recording medium is preferably a metal layer of which the optical reflectivity or density can be changed by laser exposure. The glass layer is preferably a borosilicate glass having a thickness less than 850 .mu.m.

Abstract: A method is provided for manufacturing a multicolour filter array element, firmly associated with a transparent electrode layer in a multicolour liquid crystal display device, comprising a silver halide colour photographic material wherein the colour processing of the silver halide colour material comprises a treatment of the colour processed colour material in a solution comprising at least one group III metal ion. The processing method diminishes the yellowing, due to heating, of the processed photographic silver halide colour material.

Abstract: A photographic print material suited for the production of a multicolor filter array element for use in a liquid crystal display device including a liquid crystal layer wherein the print material comprises a glass plate supporting on one side thereof (i) a silver halide emulsion layer sensitive to blue light and containing a yellow dye forming color coupler, (ii) a silver halide emulsion layer sensitive to green light and containing a magenta dye forming color coupler, and (iii) a sliver halide emulsion layer sensitive to red light and containing a cyan dye forming color coupler. The red light sensitive emulsion layer is disposed on the side of the array remote from the glass supporting plate and in each of the silver halide emulsion layers the equivalent ratio of silver halide to color coupler is at least 1 and preferably 1.2. A water-impermeable organic resin covering layer is applied over the red light sensitive emulsion layer and a transparent electrode layer is vacuum deposited over the covering layer.
