PROBLEM TO BE SOLVED: To provide a reinforced film for a vacuum displaying tube, capable of increasing a strength-advancement effect and giving an explosion-proof effect, in order to reinforce a mechanical strength of a vacuum displaying tube such as a cathode-rays tube and also without greatly increasing a weight, and to provide a vacuum displaying tube using the same film. SOLUTION: The reinforced film for the vacuum displaying tube is coated on the displaying surface 10S of the vacuum displaying tube. A raw material of the film has a molecular structure shown by formula (1) wherein an alkyl group (R) has a molecular structure shown by formula (2) or (3). |
