Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to the wall structure of a synthetic resin container that has been subjected to transfer printing. The purpose is to increase

[Prior art and problems to be solved by the invention]

When a transfer printing foil with a metal vapor deposition layer is transfer printed on the outer wall surface of a container molded from polyethylene resin or polypropylene resin, especially a container with flexible walls such as a tube container, due to the composition of the transfer foil, it is difficult to resist alcohol. The disadvantages were that it had poor hardness, oil resistance, and water resistance, and was extremely susceptible to bending.

[Means for solving the problem]

The present invention was devised to eliminate the drawbacks of the transfer printed container having a metal vapor deposited layer, and has the following configuration.

The wall structure of a synthetic resin container that has been subjected to transfer printing according to the present invention has a structure on the outer surface of a container made of polyethylene resin, polypropylene resin, etc.
The structure of the wall is transferred and printed with a metal vapor deposition layer, and the adhesive layer T6, the vapor deposition layer anchor layer T5, the metal vapor deposition layer T4, and a part of the wall K are printed on the outer surface of the wall K of the container from the outer surface side of the wall K. A transfer foil in which a pre-deposition anchor layer T3 having a layer T7 and a release layer T2 are laminated in this order.
The surface of the release layer T2 is further coated with an overcoat O made of a two-component paint, a vinyl paint, an acrylic paint, or a modified paint thereof.

[Effect]

As described above, in the present invention, the outer surface of the transfer foil Ta is coated with the overcoat O, and the overcoat O is a two-component paint (a particularly good polymeric urethane-based paint) or Since it is molded using vinyl paint, acrylic paint, and modified paint thereof, the peeling layer T2, the printing layer T7, and both vapor-deposited anchor layers T3, T5, etc.
Each layer that is sensitive to Kent-based and alcohol-based solvents can be sufficiently protected.

In addition, since the overcoat O is far more difficult to stretch and deform than the transfer foil Ta, it has a strong ability to prevent cracks from occurring due to stretching and deformation (due to bending, etc.) in the metal vapor deposited layer T4. Therefore, the decoration by the metal vapor deposition layer T4 is not deteriorated.

〔Example〕

An embodiment according to the present invention will be described with reference to the drawings.

As shown in FIG. 1, the transfer film T used in the present invention is composed of a base film T1 and a transfer foil Ta bonded to the base film T1 in such a manner that it can be easily peeled off.

This transfer foil Ta has a structure in which, from the base film T1 side, a peeling T2, a pre-evaporation anchor layer T3 having a printing layer T7 in part, a metal deposition layer T4, a post-evaporation anchor layer T5, and an adhesive layer T6 are laminated in this order. It's summery.

Since the transfer film T is synthesized as described above, when the transfer foil Ta is transferred and printed on the outer wall surface of a container made of synthetic resin such as polyethylene resin or polypropylene resin using a well-known transfer printing method, the transfer foil Ta is formed. The layers are laminated and adhered to the outer surface of the wall K in the reverse order from the above-mentioned order, starting from the outer surface of the wall K.

In this way, the transfer foil glued onto the outer surface of wall K
The release layer T2 is coated on the outer surface of Ta, that is, on the outer surface of the release layer T2, and two-component paints (polymer urethane-based, epixy-based, and modified paints thereof), vinyl-based paints, acrylic-based paints, etc. It is constructed by forming an overcoat O using a paint and its modified paint.

〔Effect of the invention〕

As is clear from the above description, the present invention can significantly enhance the alcohol resistance, oil resistance, water resistance, and bending resistance of the transfer foil Ta transferred and printed on the outer surface of the container wall K. , deterioration of container decoration due to transfer printing can be prevented. or,
Its molding is extremely simple, as it only requires transferring and printing the transfer foil Ta on the outer surface of the wall and then covering it with the overcoat O, and it has excellent functions and effects, such as not requiring any special measures. It is.
