Claims
- 1. A post-exposure treating solution for photosensitive graphic arts articles comprising:
- (a) from 2 to about 50 weight percent of a compound having the formula ##STR2## where Y is an acid group or a water soluble salt of said acid group and where R is another Y, hydrogen, an aliphatic hydrocarbon; and
- (b) about 5 to 60 weight percent of a film forming compound having fewer than 8 carbon atoms and selected from the group comprising the water-soluble mono-ester alkali metal salts of sorbitol phosphate and the alkali metal salts of .alpha. and .beta. glycerophosphate; and
- (c) sufficient water to make 100 weight percent of solution.
- 2. The solution of claim 1 wherein compound (a) is selected from the group comprising potassium and sodium salts of toluene sulfonic acid, sodium benzoate cumene sulfonic acid, sodium and potassium salts of phenol sulfonic acid, sodium xylene sulfonate, potassium quiacol sulfonate, phenyl boronic acid, benzilic acid, benzene arsonic acid, p-amino phenyl sulfonic acid, p-hydroxy benzoic acid, potassium and sodium salts of p-amino benzoic acid, anthroquinone disulfonic acid and its sodium salts and 4,5 dehydroxy m-benzene disulfonic acid.
- 3. The solution of claim 1 wherein compound (a) comprises from about ten to about twenty-five percent of the solution by weight.
- 4. The solution of claim 1 wherein said solution has a ph in the range of from about 3 to about 12.5.
- 5. The solution of claim 1 further comprising a nonionic surfactant.
- 6. The solution of claim 1 further comprising a nonionic surfactant from about 0.1 to about 10 percent of the solution by weight.
- 7. The treating solution of claim 1 wherein compound (b) comprises from about ten to about thirty percent of the solution by weight.
- 8. A post-exposure treating solution for developing or desensitizing photosensitive graphic arts articles consisting essentially of:
- (a) from 2 to about 50 weight percent of a compound having the formula ##STR3## where Y is an acid group or a water soluble salt of said acid group and where R is another Y, hydrogen, an aliphatic hydrocarbon or an aromatic hydrocarbon; and
- (b) about 5 to 60 weight percent of a compound having fewer than 8 carbon units and selected from the group comprising the water-soluble mono-ester alkali metal salts of sorbital phosphate and the alkali metal salts of .alpha. and .beta. glycerophosphate; and
- (c) sufficient water to make 100 weight percent of solution.
- 9. The solution of claim 8 wherein compound (a) is selected from the group comprising potassium and sodium salts of toluene sulfonic acid, sodium benzoate cumene sulfonic acid, sodium potassium salts of phenol sulfonic acid, sodium xylene sulfonate, potassium quiacol sulfonate, phenyl boronic acid, benzilic acid, benzene arsonic acid, p-amino phenyl sulfonic acid, p-hydroxy benzoic acid, potassium and sodium salts of p-amino phenyl sulfonic acid, p-hydroxy benzoic acid, potassium and sodium salts of p-amino benzoic acid, anthraquinone disulfonic acid and its sodium salts and 4,5 dihydroxy m-benzene disulfonic acid.
- 10. The solution of claim 8 further including as a separate ingredient a non-ionic surfactant.
