摘要： The invention relates to a developer concentrate which comprises water, at least one agent which is alkaline in water and an amphoteric surfactant and additionally at least one anionic surfactant, at least one complexing agent, at least one aminoalcohol and at least one N-alkoxylated mono- or polyfunctional amine. A ready-to-use developer can be prepared from this concentrate by dilution with tap water advantageously in the ratio of from 1:0.5 to 1:10, preferably in the ratio of from 1:2 to 1:6. The developer or the replenisher is preferably used in the production of printing plates.

摘要： A positive-working or negative-working radiation-sensitive mixture includes as an IR absorbing component a carbon black pigment having a primary particle size smaller than 80 nm. The carbon black pigment is predispersed in a polymer containing acidic units having a pK.sub.a of less than 13. The radiation-sensitive component may include an ester of (i) a 1,2-naphthoquinone-2-diazide-4-sulfonic acid or a 1,2-naphthoquinone-2-diazide-5-sulfonic acid and (ii) a compound having at least one phenolic hydroxyl group, such as 3 to 6 phenolic hydroxyl groups. After imagewise radiation exposure, the recording material including the radiation-sensitive mixture can be developed without difficulties in an aqueous alkaline solution without leaving residual coating on the areas that became soluble or that remained soluble upon exposure.
