Description

DETAILED DESCRIPTION OF THE INVENTION (1) Industrial Application Field The present invention relates to a card based on aluminum foundation PATn used for, for example, business cards, greeting cards, postcards, award display layers, nameplates, etc., and the manufacture thereof. The method is inspirational.

(b) Conventional technology Aluminum metals have a unique surface that gives off a metallic luster, and moreover, that surface is anodized. I! With the development of coloring techniques such as fermentation treatment and subsequent dyeing, it has become possible to color it in a variety of colors.

In addition, certificates made of aluminum-based metal M that utilize such surface characteristics in design have already been developed.

Products based on aluminum metal foil have a unique appearance and have the advantage of making a deep impression and impression on Buddhist people, so they are suitable for use in cards such as certificates of merit. Are suitable.

By the way, as a conventional method for forming letters and patterns on the surface of aluminum-based metal foil, the above-mentioned Aluminum Foundation! I4Wi has been proposed to undergo an etching process.

(c) The interlayer that 'A Ming is trying to solve, 6% However, when etching letters and 16 on aluminum metal foil, it requires skill and productivity. However, it is extremely expensive, and in addition, some of the aluminum metal foil that has been etched is eluted by the etching solution, and this etching solution is a serious and poisonous substance, so it is difficult to handle it. In addition, the waste liquid produced by the treatment is acidic or alkaline and cannot be discharged as it is, and requires wastewater treatment such as neutralization, precipitation and removal of dissolved ions. Waste liquid treatment TI! ．． There are problems such as the need for additional equipment and T-equipment, and the considerable expense required to dispose of the precipitates generated during this treatment.

By the way, if you look back on your daily life, for example, you may add an addendum to a business card and use it as a letter of introduction, add a personalized message to a greeting card, or write your name on an award certificate. It is not uncommon for people to write various information on the card.

However, in cards based on 7-luminium-based metal foil, a QFi anodized oxide film is usually formed on the surface of the aluminum-based metal foil by anodizing treatment, and in many cases, the anodic oxide film is Since a transparent coating layer such as acrylic resin is formed on the card, even if you try to write something on the card with a fountain pen, pencil, etc., ink or lead material will not stick to it, and the ink or pencil will not stick to the card. The core material is also extremely easy to peel off.

Furthermore, in order to improve the overall decorativeness of postcards, the back side of the card is sometimes painted or printed.

The present invention has been made in consideration of the above circumstances, and
Objective D is to provide a card made of aluminum metal foil as a base material, on which words and patterns can be easily written with a pencil, etc., or which has been imprinted to improve decorativeness. It is.

(d) Interval 3 2: f, R? The means for determining this, that is, the invention of the present MPtS1, is to print and form a required pattern layer using curable ink on the oxide film on the surface of the aluminum base RM having an oxide film, and at least a part of the back surface thereof. It is characterized in that it is formed by fixing a base sheet to an Mt layer.

In addition, the second invention of the present invention is to form an oxide film on the surface of an aluminum-based metal foil, and print a desired pattern on the oxide film on the surface of the aluminum-based gold JAM with an ink that hardens through a hardening process. On the other hand, US means that a base sheet is laminated and fixed to at least a portion of the back surface of the aluminum-based metal.

Hereinafter, first, the first invention of the present application will be explained in detail.

The aluminum-based metal having an oxide film used in the present invention refers to an aluminum-based metal in which an oxide film is formed chemically or electrochemically (anodic oxidation, oxidation) on the surface of aluminum or an alloy containing aluminum. In particular, it is preferable to form an anodic oxide film because a uniform film can be obtained.

The thickness, width, length, etc. of the aluminum metal foil (r method is not particularly limited) and may be appropriately selected depending on the application.

A desired pattern layer such as letters and figures is printed and fixed on the surface of the oxide film.

A curable ink is used for this printing, but this printing ink is not particularly limited as long as it can print on the above-mentioned oxide film.For example, official metal printing ink, printing equipment What is necessary is to adopt a printing method.

Examples of the metal printing ink include, but are not particularly limited to, oil-based inks using alkyd vehicles, electron beam/ultraviolet curable inks, etc., but the curing time after printing is extremely short and the energy is low. It is recommended to use significantly less UV-curable ink.

The above-mentioned ultraviolet curable ink usually consists of a coloring agent <A material), a prepolymer, a monomer added as necessary, an additive, and an additive.

Using the above-mentioned curable ink, using ordinary printing equipment such as sheet-fed lithography, letterpress printing, off-sera) rotary printing, overprinting, silk screen printing, gravure printing, etc.
The desired pattern layer can be printed and formed on the above oxide film by using a normal printing method, but flat metal printing, which is the most suitable sheet-fed planar printing, or letterpress printing are recommended. Ru.

Therefore, in the present invention, a base sheet is laminated and fixed to the surface of the aluminum metal foil on the side opposite to the pattern-forming surface, that is, on the back surface.

The above-mentioned base material sheet is preferably a writing sheet on which notes, messages, etc. can be written.

The above-mentioned writing sheet is not particularly limited as long as it is easily adhered to by pen ink, ballpoint pen ink, lead material, etc. For example, it can be paper, cloth, or has four minute convexes or holes on the surface. It may be constructed from a synthetic resin sheet or film having the following properties.

If the resin sheet or film is
Examples include nonwoven fabrics.

If the writing sheet itself is made of a non-adhesive material, a self-hardening adhesive layer or a Hora 1 Nord adhesive layer should be placed between the aluminum P4 board and the base sheet. It is sufficient that the aluminum-based gold YC whistle and the base sheet are attached to each other by adhesion by intervening them and applying heat and/or pressure.

When forming a base sheet (writing sheet) using a sheet or film made of resin, synthetic resin is deposited directly on the aluminum metal foil by coating, laminating, printing, etc., heating and/or heating. Alternatively, the synthetic four mt layer may be cured by applying pressure, and at the same time, it may be attached and fixed to an aluminum metal foil as a base sheet (writing m sheet).

Further, the base sheet may be used to improve the decorativeness and increase the added value of the product.

Further, the base sheet may be attached to the entire surface of the aluminum metal foil, or may be laminated and fixed to a portion thereof.

By the way, the base sheet needs to be laminated and fixed to at least a portion of the back surface of the aluminum metal foil.

That is, the base material sheet is anti-layered over the entire back surface of the aluminum metal foil. iI'X1, or may be fixed by forming an Mt layer on a part of the back surface of the aluminum metal foil.

Incidentally, if desired, the base sheet may be laminated and fixed to a portion of each of the front and back surfaces of the aluminum metal foil, or may be laminated to a portion of the surface of the aluminum base xti to form the Ii
! It is possible to finish i1.

Next, the second 51 of this application! The light will be explained in detail.
