    Abstract: A developer compsn. for developing an exposed negative working reproduction layer on a support comprises (i) water, (ii) at least one organic solvent, (iii) at least one alkaline reacting agent, (iv) at least one complex former, (v) at least one anionic surfactant, (vi) at least one emulsifier, (vii) at least one n-alkanoic acid and/or a salt of this and (viii) at least one buffer agent. Pref. (ii) is e.g. benzyl alcohol, phenoxyethanol, 1-phenylethanol, 2-phenylethanol or propyleneglycolmonomethylene. (viii) is e.g. a carbonate, phosphate, borate, alkali salts of glycine or an amine, esp. diethanolamine or triethanolamine. (v) is pref. an alka-, esp. Na octylsulphate, an alkali salt, pref. the Na salt of dodecylsulphonic acid, alkylphenolethersulphates, alkali-, esp. Na sulphosuccinates, alkyletherphosphates, alkali-, esp. Na oleic acid methyl tauride and condensed naphthalene sulphonates. (vi) is e.g. poly-N-vinyl -N-methylacetamide, water soluble copolymers of N-vinyl-N -methylacetamide, polyvinylalcohol, dextrin, gum arabic or cellulose ethers, esp. carboxymethylcellulose. (iv) is pref. a polyphosphate, esp. metaphosphate, or alkali salts of nitrilotriacetic acid or ethylenediamine tetraacetic acid. (vii) is pref. an n-alkanoic acid or salt with 8-12C, esp. caprylic acid, pelargonic acid, capric acid or lauric acid.

    Abstract: A developer for negative-working reproduction layers and process therefor. The developer includes water, an organic solvent, a surface-active agent, an alkaline agent, a complexing agent, a buffer substance, an emulsifier and an n-alkanoic compound. Use of the developer suppresses speck and fibril formation in the developing process, and can be used in reproduction layers which optionally contain a binder.
