。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a laminated film containing a hydrophilic film, and more particularly to a laminated film formed by laminating a hydrophilic film to an arbitrary material using a moisture-curing adhesive.

を接着する際に利用されている。Conventionally, there has been known a method of producing a polyurethane resin by reacting a compound having a plurality of incyanate groups (-NCO groups) with a compound having a hydroxyl group (-○H group). , used in paints and adhesives. Among them, there are moisture-curing adhesives that use water (moisture) as a hydroxyl group, such as nylon and polyvinyl alcohol! + Fat, ethylene/vinyl alcohol M
It is used when adhering a hydrophilic synthetic resin film such as a combination to any material.

、５〜５０日の時間を必要とした。Incidentally, it is known that these hydrophilic films have excellent oxygen barrier properties, and it is also known that this oxygen barrier property deteriorates as the water content increases. In order to prevent this deterioration of oxygen barrier properties, the moisture content of these films is usually suppressed to 1% or less. To bond these films to other materials, first spray water or steam on the bonding surface.
While applying moisture necessary for curing, an adhesive was applied and bonded together, and the adhesive was cured, but the curing speed was extremely slow and required 5 to 50 days.
そこで、本発明者は、この硬化速度を速めるべく鋭意研

明を完成した。Therefore, as a result of intensive research in order to speed up this curing speed, the present inventors found that either by using a hydrophilic film whose water content was adjusted to 1 to 5% in advance, or by laminating the hydrophilic film with other materials, By adjusting the water content to 1 to 5% by finely distributing water from the hydrophilic film side, the curing speed becomes significantly faster, and the oxygen and barrier properties do not deteriorate due to an increase in water content to this extent. discovered this and completed the present invention.

ィルムを含む積層フィルムである。That is, in the present invention, when bonding a hydrophilic film to an arbitrary material using a moisture-curing adhesive, the water content of the hydrophilic film is adjusted to 1 to 5% in advance, or
Alternatively, after lamination, water is added to the hydrophilic film to adjust the moisture content to 1 to 5%.The hydrophilic film can be laminated to any material using a moisture-curing adhesive. The present invention is a laminated film including a hydrophilic film, characterized in that the hydrophilic film has a water content of 1 to 5%.

水率は、常温で１週間以上保存しても変化しない。Examples of the hydrophilic film according to the present invention include nylon, polyvinyl alcohol, and ethylene vinyl alcohol copolymer. In order to make the moisture content of these films 1 to 5%, it is sufficient to treat these films in steam (the moisture content of films treated with steam in this way does not change even if stored at room temperature for more than a week). .

エージングにおいても、この含水率は変化しない。In addition, in order to achieve a moisture content of 1 to 5% after bonding with other materials, it is sufficient to apply water to the surface of the hydrophilic film using, for example, Molton containing water, which will allow the adhesive to harden. Even during aging, this moisture content does not change.

After drying under reduced pressure for 6 days, the moisture content of the laminated film was examined, and the zirconia method was used to dry the laminated film at 20°C at 65°C. :=
As can be seen from the results for RI-I and 55'C, 70 RH, when using a hydrophilic film with a moisture content of 1 to 5%, it is almost completely cured in one day. , films with lower moisture content require 6 days. Physical properties such as oxygen permeability and surface resistivity hardly change due to this increase in water content.
