Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to novel iris foils and iris powders. More specifically, the present invention relates to an iris foil to which a reflective interference filter is applied and an iris powder obtained by crushing the foil.

Conventional = 9 Buddhist altars, Buddhist utensils, folding screens, sliding doors, lacquerware, and corner ware.

For high-quality decorations such as fans, picture frames, marks, @ registers, etc., or (ζ sweets, dairy products, and other foods.

For decoration of packaging for medicines, cosmetics, cigarettes, etc.

In addition, for the production of artificial flowers, etc., the stamping foil is made using an ancient Japanese method.
Gold leaf, silver foil), but these have the disadvantage that the color tone is limited to the color unique to the metal. A metal vapor-deposited foil consisting of a film and a metal vapor-deposited powder obtained by crushing this metal vapor-deposited foil are used, and these metal vapor-deposited foil and metal vapor-deposited powder can be made into various types by transparently coloring the resin coating. There were some advantages to having colored ones, but those with iridescent luster, such as pearlescent or dazzling colors, were very frightening.However, as a result of various research, the inventors of the non-inventor discovered that they were reflective type. We have discovered a completely new fact that iris foils and iris powders with p-iris luster can be changed by applying an interference filter, and have completed our invention.

In other words, the present invention consists of at least an interference resin coating (5), a translucent metal vapor deposited film (B), and a metal vapor deposited film C), which are laminated in close contact in the order of B/A/C. An iris foil having iris luster and at least an interference resin coating (8), a translucent metal vapor deposited film (B), and a metal vapor deposit film C)
To provide an iris powder having iris luster, characterized in that it consists of broken pieces of iris foil formed by closely laminating the stiffness in the order of B/A/C.

The present invention O (whitening powder and iris powder)

・Evening 1) Forming a thin film using the Nkue, Nomanfruting method, etc., including the metal base (same as below). This means that the metal-deposited film is a semi-transparent metal-deposited film, which contains all of the metal C and film formed in accordance with the reduction and thin film process. Toniko tl-etc. metal C thin film form ε and τ: was muttered = all transparent Q gold R thin film included t-ib 7.

The thickness of the metal-based N film C1 is usually 30 to 2.
It is selected from the range of 00 mμ○, more preferably from the range of 40 to 100 mμ. The thickness of the metal evaporated film is 3atnμ, and the light reflectance of the metal 7 film is low and the iris light f1 is sufficient.
cannot be obtained and is not desirable.

On the other hand, even if the value exceeds 2'OOm,u, the light reflectance of the metal vapor-deposited film does not change, so it is undesirable from the economic point of view, regardless of the iris gloss.

Examples of metals for forming the strong metal vapor deposited film C1 include aluminum, copper, silver, and gold.

Platinum, chromium, indium, zinc, tin, nickel, titanium, etc. are used, and aluminum is usually preferred because of its light reflectance and economic efficiency. The thickness is usually in the range of 006 to 2μ, more preferably (106 to 04μ).
The range force of μ is chosen. The thickness of the interference resin coating is 0.0
If it is less than 6 μm, iris gloss cannot be obtained, which is not preferable. On the other hand 2
If it exceeds μ, the iris luster will be poor, and in addition, the iris foil will become rigid as a whole, lacking the soft and elegant texture characteristic of conventional gold and silver foil (beating foil), and will become a plate-like foil with minute irregularities, such as This is not preferable because it makes it difficult to attach it to objects to be decorated such as Buddhist altar fittings.

The resin for forming the interference resin coating includes thermoplastic resin, thermosetting resin, electronic hardening resin, and ultraviolet I hardening resin.
! Any curable resin may be used, such as acrylic resins, vinyl-enhanced vinyl-hinyl acetate copolymers, and polyvinyl petyral.

Polycarbonate, nitrocellulone, cellulone acetate, urethane resin, urea resin.

Melamine thread resin, urea-melamine thread resin, epoxy resin, alkyd resin, aminoalkyd resin, rosin-modified maleic pine resin, etc. alone or blends of the two are often used.

Formation of an interference resin coating (7) Conventional methods such as an organic solvent solution of the resin, a water bath solution, a traroll coating method, a gravure coating method, a reverse coating method, a Nupilay coating method, etc. to form an interference resin coating film. This is done by applying by a coating method and drying (curing in the case of thermosetting resin, electron beam curable resin, ultraviolet curable resin, etc.).

In the iris layer of the present invention, the thickness of the translucent metal vapor-deposited film is usually selected from the range of 1 to 20 mμ, preferably from 5 to 15 mμ. The thickness of the semi-transparent metal vapor deposition film is 1mmμ
If it is less than this, the translucent metal vapor deposited film has almost no light reflectivity, so the iris gloss cannot be changed, which is not preferable. On the other hand, 20rnμ
If it exceeds this value, the reflectance of the semi-transparent metal vapor deposited film is too high and causes specular reflection, which is not preferable because the gloss of the iris cannot be changed.

As the metal for forming such a semi-transparent metal vapor deposited film (B), for example, those used in the metal vapor deposited film Ω are preferably used, and the metal forming the metal vapor deposited film and the semitransparent metal vapor deposited film are preferably used. ii may be the same or different from the metal.

In the iris layer of the present invention, since the metal vapor deposited film C) and the semitransparent metal vapor deposited film (B) that constitute the iris layer have low mechanical strength and are easily damaged by friction, the metal vapor deposited film and the semitransparent metal vapor deposited film (B) A protective resin coating is provided on the surface of the film, especially on the surface of the translucent metal vapor-deposited film.1 The thickness of the protective resin coating is not particularly limited, but it is usually selected appropriately from a range of about 0.1 to 2 μm. It will be done.

As the resin for forming such a protective resin coating, for example, those used in the interference resin coating (a) are preferably used, and the resin forming the interference resin coating and the protective resin coating are preferably used. The forming resins may be the same or different.

The protective resin coating 2 may be colored with a coloring agent such as a dye or pigment in cases where it is transparent or translucent. Furthermore, the protective resin coating formed on the surface of the metal vapor deposited layer C) may be opaque.

The uninvented iris layer is coated with a protective resin coating (if necessary) on the support.
An undercoating film) is provided, and an interference resin coating film, a translucent metal vapor deposition film (B), and a metal N film C) are formed thereon, and at least these are closely laminated in the order of B/A/C. That is, (1) a translucent metal vapor deposited film (B), a dry resin coating layer, and a metal vapor deposited film C) are provided in this order. (2;

Translucent metal evaporation upper side [F]) 2 This I layer is provided to form an iris layer, and if necessary, a protective resin coating (top coating)
It can be easily seen by peeling off the iris layer (the groove fc is an integral structure of this and the protective resin coating) from the support.

As a support, it has sufficient self-retention properties and a smooth surface, and n can be any n, such as polyenether or polyamide.

Polyamide-imide, polyethylene, polypropylene, cellulone acetate, polycarbonate, polyvinyl chloride, fluororesins, pine resins, cellophane, and other film-like or sheet-like materials; A sheet-like material, a glass plate, etc. are used as appropriate.

Various methods can be employed for peeling off the support cam of the iris layer (or a monolayer structure of this and a protective resin coating) - for example, peeling the iris layer directly onto the support or through a release layer. A method is available in which a layer is provided and the attached layer f'L is mechanically peeled off. Mechanical peeling (e.g. by scratching the iris foil on the prongs), stretching or bending the laminate consisting of the support plate and the iris foil, or applying vibration to the laminate. Alternatively, the laminate may be stretched by bending or vibrating the laminate to facilitate peeling. As for the above board, the thickness of the fat S film-like material is about 6 to 1 (:0μ
Something like that? The method in which the laminate is peeled off by stretching the laminate with the gills is preferable because it can produce a large amount of continuous iris material without wrinkles or cracks.
By the way, the embroidery method is not good when the support is the iris 7-! 'S Aini (・; Silicone resin, wax, interface old quality,
metal oxide.

The surface of the support may be treated with a fluororesin or the like.

□ Also, a resin film soluble in water or an organic solvent is spread on the support, an iris foil (or an integrated structure of the protective resin film and the stiffness) is placed on top of this, and then this laminate is coated with water or an organic solvent. An example of this method is to peel the iris foil from the support by immersing it in "Arisakura Housai" to dissolve the resin film. In this case, the support, the interference resin coating, and the protective resin coating are made of materials that are not susceptible to water or organic solvents used to dissolve the resin coating.As the resin for the resin coating, , such as polyvinyl alcohol, polyvinyl butyral, gelatin, casein, methylcellulose, ethylcellulose.
