Abstract

PURPOSE: To widen the reflection directivity to the transverse direction of the screen for projection and prevent the damaging and staining of its surface by forming a finely uneven surface on an Al foil, and coating the protecting film thinner of thickness than the height of the unevenness thereof by the specific method.
CONSTITUTION: An aluminum foil 1' and an other guiding film 1" are superposed and are fed in the arrow direction between guide rolls 5A, 5B and rolling oil 6 is flowed to make the foil 1 having an uneven surface 1a orthogonal to the feed direction of the foil 1" of the fine waveforms of the height about 3μ on the surface making opposing contact with the guide film 1". The foil 1 is bonded onto the surface of a screen substrate 2 and the coating liquid 9 comprising dissolving the copolymer of vinyl chloride and vinyl acetate in a solvent having a boiling point sufficiently higher than room temperature (n-butyl acetate or the like) is flowed on the foil 1 placed on a rotary table 8. After the coating liquid 9 is spread over the entire surface by 10rpm first, the speed is increased up to 40rpm to shake off the excess coating liquid. After this, it is dried by an infrared ray heater, whereby the protecting film 3 of 0.9W1μ thick is formed. In this way, the uneven surface 3a corresponding to the unevenness 1a of the aluminum foil 1 is formed.
