Abstract: A liquid for removing printing and screen printing inks consists of an essentially anhydrous mixture of (a) .gamma.-butyrolactone and/or N-methyl-2-pyrrolidone in an amount of up to 25% (v/v) and/or (b) propylene carbonate in an amount of up to 90% (v/v), and (c) up to 90% (v/v) of a high-boiling aromatic compound or a mixture of such compounds having a relative evaporation rate with respect to N-butyl acetate of 0.01 or less. Such a liquid can remove all printing and screen printing inks, and it is considerably less unhealthy than the known cleaning liquids.

Abstract: A liquid for removing printing and screen printing inks comprising an essentially anhydrous mixture containing:(a) q-butyrolactone and/or N-methyl-2-pyrrolidone in an amount of 1-25% (v/v);(b) one or more propylene glycol derivatives selected from substituted propyl acetates and/or propylene glycol ethers; and optionally(c) a diluent selected from aliphatic compounds having a flash point above 22.degree. C. and a content of aromatic compounds below 1%; and/or(d) a surfactant, the amount of components (b), (c) and (d) constituting 99-75% (v/v) of the liquid.
