Abstract
New developer composition for holography and photolithography. The composition is a mixture in solution which comprises ascorbic acid, 2-amino-4-chlorophenol, phenidone or pyrogallic acid, a pH fixing substance and, optionally, urea. The preferred concentrations of said components are as follows: 4-30 g/l of ascorbic acid, 95-5 g/l of 2-amino-4- chlorophenol, 0-5 g/l of phenidone, 0-30 g/l of pyrogallic acid and 0-150 g/l of urea. It has industrial applications in the techniques of holography and photolithography.
