Abstract
PURPOSE:To obtain an Fe-Ni alloy sheet having superior etchability and giving a high quality uniform shadow mask by mask by carrying out final annealing before final cold rolling in an atmosphere consisting of hydrogen and nitrogen in a specified volume ratio. CONSTITUTION:An Fe-Ni alloy is melted, cast, forged, hot rolled and pickled. It is subjected to properly repeated cold rolling and annealing, and final annealing before final cold rolling is carried out in an atmosphere consisting of >=95vol% hydrogen and the balance nitrogen. The final cold rolling is then carried out to obtain a metallic sheet for a shadow mask. When holes for passing electron beams are pierced in the metallic sheet by etching, a high accuracy shadow mask for color picture tube can be produced.

ーニングを経てエツチング工程に進む。エツチング工程
ではエツチング液として塩化第２鉄を用いた。In the etching test, first, the substrate is degreased and cleaned, and then a photosensitive solution containing alkali milk caseinate and ammonium dichromate is applied to both surfaces to form a predetermined resist film. Next, a pattern having a negative image of large and small mask holes is placed in close contact with the photoresist film on both sides, and an image of the mask holes is obtained by exposing with an ultra-high pressure mercury lamp. After that, it goes through development, drying, and burning before proceeding to the etching process. In the etching process, ferric chloride was used as an etching solution.
