Abstract: 1475598 Colour television tube PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 23 July 1974 [26 July 1973] 32538/74 Heading H1D On a shadow mask 7 of a colour tube (Fig. 1 not shown), the side facing the multiple electron guns is protected from local deformation due to temperature change by a thin double layer film 12-11 receiving the majority of emitted electrons, this film being in poor thermal contact with mask 7. The film is separated from the mask 7 by a layer of porous granules 10 formed on the mask comprising e.g. MnO 2  sprayed and dried. An acrylic skin, removable thermally later is then temporarily coated over layer 10 to receive vapour deposited Al 0À5 micron layer 11. This radiates heat poorly towards mask 7, and to increase its backward radiation towards the electron guns a further black layer 11 of NiO or Ni-Fe is vapour deposited. The acrylic layer is blown out of apertures 8 directly it has been formed: if granules 10 are omitted the acrylic layer pulls back from the edges and allows the Al layer to be formed out of contact with mask 7, followed in this case by a colloidal graphite sprayed outer coating.
