Definitions
- Any substitutents may take the place of hydrogen atoms of the amino-group', j for instance alkyl,. arylor acyl.
- This new group of developers comprises both slow developers which are active only in caustic alkaline solution and also rapid'developers which act in presence of sulflte alone.
- A. particular advantage of the new developers is that many de-- velop under certain conditions directly in color without addition of a second component.
- Aliphaticmembers of the group are, for example, diethylamino-acetone, which is a feebly active developer, aminoacetic acid ethyl ester, aminobenaoyl-acetic acid ethyl ester, and like bodies.
- the heterocyclic group there may be -mentioned in particular the derivatives of 4- amlnopyrazolone-(B), the. hydrazide of orthoamin'o-phthalic acid, 3-amino-4-keto-2-iminotetrahydrothiophene and, 8 amino-4-hydroxy'-2- keto-furane-dihydride.
- Example 3 The following developer yields, besides the silver picture an intensely yellow dyestuflf picture, which remains when the silver picture has been dissolved, for example by conversion into silver halide and fixing:
