摘要： An anti-reflection film (2) is produced on the panel surface of a cathode-ray tube (1) by:

(A) preparing a solution (8) for forming an anti-reflection film (2), which contains water and an alkoxide having the formula,

M(OR) n

wherein M is Si or a metal selected from the group consisting of Ti, Al, Zr, Sn, In, Sb and Zn; R is an alkyl group having 1-10 carbon atoms; n is an integer of from 1 to 8; and when n is not 1, the alkyl groups represented by R may be the same or different,
(B) coating the solution (8) for forming an anti-reflection film (2) on the outermost surface of the panel of a cathode-ray tube (1), and
(C) applying an ultraviolet light (7) to the solution (8) for forming an anti-reflection film (2) coated on said surface to cure the solution to form a transparent film with fine roughness.

This production method is carried out using an apparatus having:

(a) a coating means (3) for coating the above solution (8) for forming an anti-reflection film (2) on the outermost surface of the panel of a cathode-ray tube (1),
(b) a transferring means (4) for transferring the solution-coated cathode-ray tube (1), and
(c) an ultraviolet light-applying means (7) for photocuring the solution (8) coated on the cathode-ray tube (1) during the transfer of the solution-coated cathode-ray tube.

In the above method, when a silicon alkoxide is used as the metal alkoxide, there can be obtained a cathode-ray tube having an anti-reflection film made of alkali-free silica on the outermost surface of the panel, said anti-reflection film giving a ratio of Si-O-Si peak intensity to Si-OH peak intensity of 4 or more when measured for infrared spectrum.
Further embodiments include an antistatic layer and the inclusion of an organic dye into the anti-reflection film.
