摘要

Process for detackification of water-dilutable paints and of solvent-borne paints, characterised in that the said paints are treated by washing with an aqueous detackifying phase whose pH is from 4.5 to 7 and preferably from 5 to 6 and which contains an effective quantity of at least one detackifying agent consisting of an amino molecule of formula IMAGE or of formula: IMAGE in which the substituents R1 to R7, which may be identical or different, denote: - a hydrogen atom, - a radical of formula -O-Re in which Re is chosen from the group comprising hydrogen and a C1-C4 saturated aliphatic hydrocarbon chain, it being understood that the substituents R5 to R7 are not all simultaneously hydrogen atoms, or of a hydrate or else of an organic or inorganic acid salt of the abovementioned amine molecule, preferably a salt of sulphuric, phosphoric or hydrochloric acid.
