SCREENING AGENT

The invention relates to a screening agent comprising (a) a pigment, (b) a binder and (c) an adhesion promoter, wherein the binder is a natural polymer with a weight-average molecular weight of 200,000 to 1,000,000,000 g/mol. The screening agent can be used to form a protective layer that can be rem...

Zusammenfassung:	The invention relates to a screening agent comprising (a) a pigment, (b) a binder and (c) an adhesion promoter, wherein the binder is a natural polymer with a weight-average molecular weight of 200,000 to 1,000,000,000 g/mol. The screening agent can be used to form a protective layer that can be removed using a removal agent that contains a base and optionally a complexing composent. L'invention concerne un agent de criblage contenant (a) un pigment, (b) un liant et (c) un promoteur d'adhésion, le liant étant un polymère naturel présentant une masse moléculaire moyenne de 200,000 à 1,000,000,000 g/mol. Cet agent de criblage peut servir à former une couche protectrice qui peut être ôtée au moyen d'un agent de retrait contenant une base et, facultativement, un composant complexant.
