CONSTITUTION:This ink-removing agent contains a compound of the formula (X<1>, X<2> are independently H, hydrocarbon group, or X<1>, X<2> are combined to each other to form a CH=CH-CH=CH; R<1>, R<2> are independently lower alkyl), e.g. dimethyl phthalate. The content of the compound of the formula is 10-50wt.%, preferably 20-40wt.%, based on the ink-removing agent.</p> |
