Abstract
<PICT:0929090/III/1> An image display tube comprises a glass bulb 1 coated, at least over a zone adjoining the image area 3 and extending over part of the bulb, with a synthetic resin layer 5 including fibrous material. The bulb may be coated with a mixture of 3 parts by weight of glass fibres having a length of from 1 to 3 cms. and 7 parts of a solution of an unsaturated polyster in styrene, which may also contain dyes and pigments, and fillers to counteract shrinking and cracking during hardening. For improved adherence, a layer of polyvinyl acetate may be provided between the bulb 1 and layer 5. In an alternative embodiment a fibre-glass cord is wound on the bulb while it is sprayed with polyester resin, Fig. 2 (not shown.) The synthetic resin layer may also serve to provide the tube with mounting lugs, and may be covered with a conductive layer, or may itself be rendered conductive by the addition of metal or graphite particles or by incorporating metal gauze fibres in the layer.
