Solvent mixture for the development of lithographic printing plates, without organic solvents and having an extremely neutral pH

摘要

the invention concerns a entwicklergemisch, free of organic solvents and a ph of about 6.5 to 7.5 or contg.(a) 0.1 to 20 wt.%, based on the total weight of the developer, at least one connection from the group comprehensive natriumoctylsulfat, natriumtetrau00addecylsulfat, sodium - 2 - ethyl - hexylsulfat and ammou00adniumlaurylsulfat, (b) 0.1 to 30% by weight.-%, relative to the total weight of the developer, at least one connection from the group comprehensive the lithium salts of hydroxy, aryl and alkylcarbonsu00e4uren, (c) 0.1 to 30% by weight.-%, relative to the total weight of the developer, at least one connection from the group comprehensive the potassium salts of hydroxy, aryl and alkylcarbonsu00e4uren, d) where appropriate, organic or inorganic, with the remaining mixture with acid or base, each for one tellung of entwicklergeu00admischs at a ph between 6.5 and 7.5 adequate quantity(e) where appropriate, up to 0.05% by weight, relative to the total weight of the developer, a entschu00e4umungsu00admittels sowief) rest in water up to a total of 100 wt.%.;the mixture is particularly to the development of belichteter, negative working plates with a carrier of aluminium are suitable.
