ABSTRACT:
A method of preparing an in-mold label is described in which a resin film is embossed to form a gravure pattern having from 60 to 200 roll-formed lines per inch. The embossed film is stretched and then coated on its embossed pattern side with a heat-sensitive liquid resinous adhesive in an amount of from 1 to 10 g/m.sup.2 on a dry resin basis. The applied adhesive is then dried to form an adhesive layer on the film. The in-mold label obtained by the present invention is excellent in printing suitability including feeding properties and ink adhesion, has an advantage that die-cutting for producing the label can be conducted at a high efficiency, and is less apt to develop blisters even under a wide range of molding conditions when used in in-mold application.
