Method for removing printing and screen printing ink |
摘要 |
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.
