<p>PURPOSE:To enhance the ink transferability and adhesion at ultraviolet printing by a method wherein water solution containing modified polyethylene-mine represented by a specified formula is applied on a polyolefin film and, after that, dried so as to form a coat. CONSTITUTION:Water solution containing modified polyethyleneimine represented by the formula I, in which A represents the formula II or polyamine-polyamide residue, R<1>-R<4> represent independently hydrogen, alkyl group having the number of carbons of 1-24, alkenyl group, aliphatic cyclic hydrocarbon group or benzyl group under the condition that at least one is a group excluding hydrogen, (m) represents an integer having a value of 0 to 300, and (n), (p) and (q) represent integers each having a value of 1 to 300, is prepared. Said water solution is applied on a polyethylene film and dried so as to form a coat in order to produce a thermoplastic resin film excellent in printability.</p> |
