STABLE HIGH PH DEVELOPER
Document Type and Number:
WIPO Patent Application WO2006063626
Kind Code:
A3
Abstract:
Developer composition obtainable by (a) providing water, (b) dissolving such an amount of an alkaline component selected from alkali silicates, alkali hydroxides, Na3PO4, K3PO4, NR4OH, wherein each R is independently selected from C1C4 alkyl groups and C1-C4 hydroxyalkyl groups, and mixtures thereof in the water provided in step (a) that a pH of more than 12 is obtained, and (c) dissolving a stabilizer selected from M2CO3, MHCO3, or a mixture of 2 or more thereof, wherein each M is independently selected from Li, Na, K and NR'4 and each R' independently represents H or C1-C4 alkyl, in the solution obtained in step (b) wherein the amount of the added stabilizer is such that the amount of the added carbonate anion is 1.5 to 20 wt-%, based on the total weight of the developer composition.
