Abstract
An electrolyte for the development of a visible image on a photoconductive layer, which has been or is being exposed to a light image, by cathodic deposition of silver and/or silver sulphide or oxide, comprises an aqueous solution containing silver ions complexed with one or more o -aminoalkanethiols or oligomers thereof of the formula <FORM:1007582/C6-C7/1> where R and R1 are each hydrogen; alkyl groups which may be substituted with hydroxyl, amino, alkoxy, or further alkyl groups; alkenyl groups; or cycloalkyl groups such that in all cases neither R nor R1 contains more than 6 carbon atoms; or R and R1 form together with the nitrogen atom a 5- or 6-membered heterocyclic ring: R2 is hydrogen or hydroxymethyl; p is 1, 2 or 3; and n lies between 1 and 7. The solution which preferably has a pAg of 7 to 11.5, provided by soluble silver salts or by adding insoluble silver compounds to a solution of the complexing agent, may also contain 3-5% of calcium or magnesium acetate together with acetic acid and may be adjusted to pH 6 to 8 with 2-aminoethanol. The applied potential is preferably from 30 to 80 volts. In examples using a Zn-O-inresin photoconductive layer, the applied potential is 60 volts. Specification 1,007,581 is referred to.ALSO:o -Aminoalkanethiols of the general formula <FORM:1007582/C2/1> where R and R1 are each hydrogen atoms; alkyl groups which may be substituted by hydroxyl, amino, alkoxy, or further alkyl groups; an alkenyl group; or a cycloalkyl group; and neither R nor R1 contains more than six carbon atoms; or R and R1 form together with the nitrogen atom a 5- or 6-membered heterocyclic ring such as a pyrollyl, morpholino, piperidino, piperazino, or N-methylpiperazino ring: R2 is hydrogen or hydroxymethyl; p is 1, 2 or 3; and n lies between 1 and 7 are prepared from the corresponding amine (R)(R1)NH by the reaction <FORM:1007582/C2/2> effected by refluxing a non-polar solvent mixture of the reactants. Different molar proportions and the oligomers produced for o -amino-ethanethiols are given in Table 1 of the Specification, compounds having a value of n which is an integer being obtained by fractional distillation of the reaction product. Complexes are formed by adding the compounds to distilled water solutions containing silver ions or adding water-insoluble silver compounds to solutions of the o -aminoalkanethiols. Specification 1,007,581 is referred to.
