Abstract
1483307 Etch resistant stencils RCA CORPORATION 12 Sept 1975 [12 Sept 1974] 37658/75 Heading G2C [Also in Division H1] An etch-resistant stencil is produced by coating a substrate with a light-sensitive resist comprising an alkali metal or ammonium caseinate, an alkali metal or ammonium dichromate sensitizer, and water, and having a pH in the range from 5.8 to 7.0, drying and imagewise exposing the coating developing to remove the unexposed portions and baking the remaining resist to render it etch resistant. The resist is preferably sodium caseinate and ammonium dichromate and may also include sodium borate. The substrate may be a regularcarbon or low-carbon cold-rolled steel sheet, coated on both sides with the resist. After the resist is baked the sheet may be etched to form a shadow mask for a colour television tube.
