<p>A thermoplastic resin film having improved printability is described, which is formed by coating a polyolefin film with an aqueous solution containing a modified polyethylene-imine represented by the following general formula: <IMAGE> where A is <IMAGE> or a polyamine-polyamide residue; R1-R4 are each independently H, an alkyl or alkenyl group having 1-24 carbon atoms, an alicyclic hydrocarbon group or a benzyl group, provided that at least one of R1-R4 is a group other than H; m is 0-300; and n, p and q are each a number of 1-300, and drying the coated solution to form a surface coating.</p> |
