The present invention relates to a vapor-deposited hot stamp film, particularly a metallic transfer colored magnetic tape. Vapor-deposited hot stamp film is used as a thermal transfer film by vapor-depositing metals such as aluminum, tin, or zinc to hide the magnetic layer etc. when manufacturing magnetic cards. It has been observed that the deposited layer corrodes and dissolves during use, and this phenomenon tends to be particularly accelerated in salt, acid, or alkaline atmospheres. For example, the structure of a conventional metallic transfer colored magnetic tape is as shown in FIG. 1, in which a release layer 3, an OP varnish layer 4,
Colored layer 5, vapor deposition layer 7, magnetic layer 11 and adhesive layer 1
2 are laminated, of which the vapor deposited layer 7 is the magnetic layer 1.
1, and is composed of a vapor-deposited metal thin film of aluminum or tin, but the aluminum, tin, and zinc that make up this vapor-deposited layer 7 are highly activated metals, and they do not react in an ionic atmosphere. It ionizes, causes an electrical reaction, and corrodes, generally resulting in poor adhesion and deterioration of the physical properties of the magnetic tape, such as abrasion resistance and cross-cut cellophane tape peeling. Therefore, in order to compensate for the lack of adhesion (adhesiveness) of the vapor deposited layer 7, the anchor layers 6 and 8 are often provided using an anchor agent. As the material of this anchor agent, resins such as vinyl, acrylic, and urethane are used. However, although such anchoring agents have excellent magnetic properties such as magnetic properties and electromagnetic conversion properties, they have problems in chemical strength such as acid resistance, alkali resistance, and solvent resistance. It has also been proposed to use a resin with excellent moisture resistance (such as vinylidene resin) as an anchoring agent in order to improve the chemical strength of the deposited layer, but it has not been possible to obtain a satisfactory effect in practice. do not have. In particular, in a 24-hour immersion test in salt water, alkaline aqueous solution, or acidic aqueous solution, the deposited layer is completely immersed. For these reasons, it is desired to develop a technology that can satisfy all of the physical strength, chemical strength, and magnetic properties of vapor-deposited hot stamp films such as magnetic tapes. The present invention has been made in view of the above circumstances, and an object thereof is to provide a vapor-deposited hot stamp film that can practically satisfy all of physical strength, chemical strength, and magnetic properties. It is. Corresponding to this object, the vapor-deposited hot stamp film of the present invention is a vapor-deposited hot stamp film in which an anchor layer is interposed between at least a magnetic layer and a metal vapor-deposited layer, the anchor layer comprising It is characterized by using a modified alkyd resin as the main component of the anchor agent. The details of this invention will be explained below. When the vapor-deposited hot stamp film of the present invention is applied to a metallic transfer-type colored magnetic tape 1, the layer structure is as shown in FIG. layer 4, colored layer 5,
It is formed by laminating an anchor layer 6, a vapor deposition layer 7, anchor layers 6 and 8, a magnetic layer 11, and an adhesive layer 12. What is particularly important here is the material that constitutes the anchor layer 8. In this invention, a modified alkyd resin is used alone or in combination as a curing agent as the material for the anchor layer 8. The modified alkyd resin referred to herein refers to fatty acid-modified alkyd resin, resin-modified alkyd resin, and the like. Furthermore, sufficient characteristics can be obtained when the thickness of the anchor layer is in the range of 0.5 to 2.0 μm without affecting the electromagnetic conversion characteristics.
Further, although the anchor resin can be effective with just the resin, the same or better effect can be obtained by adding a stable pigment such as titanium oxide (TiO 2 etc.) to the anchor resin. Further, the anchor layer 6 between the colored layer and the vapor deposited layer 7 is the same, and if the colored pigment of the colored layer 5 and the vapor deposited metal are likely to cause an electrical reaction, the effect can be obtained by performing the same treatment. The modified alkyd resin used for the anchor layer is
It is based on oil-modified alkyd resin, and is modified with other component resins. If the oil length is short during oil denaturation, the coating film will be too hard and brittle.
Further, pigments such as titanium oxide have poor dispersion, which is undesirable. Long oils have poor coating strength and take too long to harden, making them impractical; medium length oils are used in the present invention to give the best results. As a modifying resin, medium oil modified alkyd resin alone shows good results, but if it is compatible with this resin, equally good results can be obtained.Among them, styrene modified, acrylic modified, and styrene acrylic modified The resin exhibited excellent properties such as adhesion, moisture resistance, water resistance, salt water resistance, acid resistance, and alkali resistance. In addition, epoxy-modified, polyester-modified, and vinyl-modified resins can also be used. Since this modified alkyd resin is of the oxidative polymerization type, no curing agent is used, but even better results can be obtained by adding cobalt, which promotes oxidative polymerization. What is particularly important is that when an isocyanate is used as a curing agent in this modified alkyd resin, a material can be obtained that has coating film properties that are several orders of magnitude better than those of conventional modified alkyd resins. In particular, when used together with a cobalt-based curing agent, the strength of the coating film (adhesion, toughness, water resistance, moisture resistance, solvent resistance, chemical resistance) is further improved. Furthermore, since the oil-modified alkyd is the main component, this coating film has lipophilic properties and functions to suppress the electrochemical reaction occurring between the vapor-deposited metal layer and the magnetic layer, thereby preventing the electrolytic corrosion reaction of the vapor-deposited layer. In addition, by improving the dispersibility of titanium oxide, which has very good stability, it is possible to increase the pigment content ratio to about twice that of ordinary white pigments, which also has the effect of preventing reactions between the vapor deposited layer and the magnetic layer. increases.
