| abstract | 1,113,508. Etching. W. H. HOWSON Ltd. 8 Dec., 1966 [9 Dec., 1965], No. 52215/65. Heading B6J. [Also in Division G2] Photolithographic plates are produced by (i) coating an anodized aluminium or aluminium alloy support with a light-sensitive material, (ii) image-wise exposing and developing the, coating, (iii) etching away the exposed anodized surface to reveal the aluminium, (iv) depositing a layer of ink-accepting metal (e.g. copper) on the aluminium, (v) optionally coating the copper with a greasy ink or protective lacquer and (vi) removing the resist from the support. Etching agents which may be used are alkali metal hydroxides, sodium zincate, ferric chloride and hydrochloric acid, copper borofluoride, hydrofluorosilicic acid, sodium dichromate and phosphoric acid, and hydrofluoric acid. The preferred etching solution is hydrofluoric acid in monoethylene glycol. |
