- a method for obtaining an easily adhered polyester film has been proposed.
- the defoaming agent and surfactant contained in the coating agent cause phenomena such as spots and whitening during vapor deposition.
- a plastic film with improved adhesiveness without using an agent or a surfactant has been proposed.
- troubles are likely to occur.
- a non-stretched or uniaxially stretched polyamide film which has not been heat-treated has a specific surface activity. After applying a specific amount of a coating agent containing a coating agent, it is stretched and heat-treated in at least one direction, so that it can be applied without problems in the preparation of the coating agent and the coating process, adhesiveness, and ink printability. Adhesion with printing inks, laminating films, coating agents, etc., especially without damaging the transparency, slipperiness and blocking resistance of the raw film It was found that the present invention could be improved, and the present invention was completed.

If the T g is less than 40 ° C, apply Locking occurs, the trace of adhesion remains as a transparent spot, and if it is more severe, it cannot be rewound, and if it is forcibly rewound, the film will break.
- the present invention is an in-line coating in which the polyamide film is coated and then stretched, if the Tg is higher than the drying temperature after the coating and the temperature required for stretching, it is difficult to form a uniform coating film. This is because the minimum film formation temperature (MFT) for forming a continuous coating film is generally around Tg, and is preferably less than 150 ° C.

- the spherical particles mean that the minor axis / major axis is 0.90 or more in the electron micrograph. It is preferable that the fine particles have a true spherical shape, because they have excellent effects on blocking resistance and slipperiness, and that there is little decrease in transparency.
- the average particle diameter is less than 0.001 m, there is no effect on the blocking resistance and the slipping property. If the average particle size exceeds 1.0 m, printability will deteriorate. In the case of photo printing in particular, ink dropouts occur in highlights.
- the fine particles may be inorganic or organic, but need to have heat resistance so that they are not deformed during the manufacturing process and lose their effects.
- fine particles have a function of an anti-blocking agent and a slip agent that imparts appropriate slip properties in post-processing steps such as winding, printing, laminating, and painting.
- Preferable fine particles include, for example, colloidal silica “Snowtex” ST-C (average particle diameter 0.010 to 0.020 m), ST-XS (average particle diameter 0) manufactured by Nissan Chemical Industries, Ltd. 0.004 to 0.006 m) and the like, but is not limited thereto.

- the amount of the fine particles (C) is defined as C / (A + B) as a ratio to the total amount (A + B) of the aqueous polyurethane resin (A) containing the surfactant and the water-soluble polyepoxy compound (B). ) Is 0.1 / 1 0 0 ⁇ 1 0 1 0 0. If this ratio is smaller than 0.1 Z100, the effect on blocking resistance and slip resistance is insufficient, and conversely, if it is larger than 100/1100, the effect does not change and it is economically disadvantageous. is there.
- the coating amount of the water-based polyurethane resin containing a surfactant, the water-soluble polyepoxy compound and the water-based coating agent containing fine particles as a main component is 0.005 to 0.030 g / dry weight after stretching. m2, preferably from 0.010 to 0.025 gm2. If it is less than 0.05 g / m2, a uniform coating film cannot be obtained, and the water resistance and adhesiveness are insufficient. Conversely, if the coating is 0.030 g / m2 or more, the coating surface becomes more likely to block on the non-coating surface. Also, no improvement in performance was observed, which was not desirable because it increased costs.
