Braun tube with a mark for reading and a method for manufacturing the mark

摘要

The present invention provides a method of manufacturing a cathode ray tube and a mark (2) to which a mark (2) attached to a side (1b) of the panel (1) is marked with a mark (2) The base layer 2a of the white heat-resistant acid-resistant coating and the undercoat layer printed on the undercoat layer 2a are formed on the side surface 1b of the panel 1, A mark 2b made of a heat resistant ink for displaying contrast and a mark 2 made of a transparent heat-resistant acid-resistant paint finish coat 2c coated on the mark 2b were formed. In order to form the mark 2, a base made of a white heat-resistant acid-resistant paint is first applied, and then an ink jet recording apparatus accommodating a heat-resistant ink for displaying a good contrast with respect to the base color on the base, (2b) is printed on the mark portion (2b), and a finish paint made of a heat-resistant acid-resistant paint is applied over the mark portion (2b).
