Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a suede-like surface imparting material used to impart a soft and distinct matte appearance similar to suede. [Prior Art] Various methods are used to make surfaces matte in various fields such as furniture, building materials, and light electrical appliances. For example, there is a method of directly applying suede paint (matting ink), which is a solvent-soluble resin material with bead pigments such as acrylic beads or nylon beads added to the vehicle, on the surface of the object. There are problems in that coating unevenness tends to occur on the surface, making it impossible to obtain a uniform and beautiful matte surface, and in addition, the cost is high. The above-mentioned bead pigments are made by converting the surface of fine powder of ordinary pigments such as Fezes, Ti01, CaCO3, and quinacridone into repellent materials such as polyurethane, acrylic, epoxy, polyester, nylon, fluororesin, vinyl chloride-vinyl acetate copolymer, etc. It is coated with a certain resin, and the vehicle is the same as that used in ordinary inks, such as urethane resin. In addition, as other matte imparting means, decorative sheets having a finely uneven surface and transfer foils that impart a finely uneven surface layer by transfer are also known. The finely uneven surface of a decorative sheet can be formed by: ■ A surface created by sandblasting, embossing, etc., ■ A matting agent kneaded into the resin material that forms the surface layer, and ■ A surface created by incorporating a matting agent into the resin material that forms the surface layer. There are those with a chemical matte surface, and those with a coating matte layer applied to the surface of the base material, but all of these have a 75" surface gloss value of approximately 2.0 to &0%.
The matte effect was not very strong. In addition, even with transfer foil constructed using a matte film with fine irregularities as described in ■ to ■ above, the surface of the resin layer that is transferred and formed by peeling off the matte film has small irregularities and has the same gloss as above. The value was about ZO ~ 7.5%, and the matting effect was low and the design was lacking.
In any case, conventional means for imparting a faded appearance are mainly those with a surface gloss value higher than 2.0% at 75°, and have not been able to impart a distinctive faded appearance. In recent years, there has been an increasing demand for products with super matte surfaces, and there has been a desire for a means to easily and inexpensively impart an excellent matte appearance similar to that of suede. The present invention was made in view of the above points, and provides a suede-like surface imparting material that can easily and inexpensively provide a surface condition that has a distinctive matte appearance similar to that of suede, and is also excellent in feel and design. The purpose is to [Means for Solving the Problems] The present invention provides the following features: (1) Using a releasable binder resin to which fine particles having a spherical shape or a shape similar to a sphere are added, the center of gravity of the fine particles protrudes from the average level plane of the binder component coating film.

On the shaping film provided with a finely uneven coating layer of m,
A suede-like transfer foil characterized by being provided with a suede-like surface shaping resin layer having at least an inwardly expanded concave portion. (6) The transfer foil according to claim 5, wherein the fine particles are silicon. The gist is: [Example] Hereinafter, an example of the present invention will be described based on the drawings. The suede-like surface-imparting material 1 of the present invention includes at least a resin layer 4 having a suede-like surface 3 having concave portions 2 with an inwardly expanded surface as shown in FIG. The suede-like surface 3 is produced using a forming film 6 having a finely uneven coating layer 5 on a base material 14 as shown in FIG.
As shown in the figure, the surface shape of the finely uneven coating layer 5 is changed to the resin layer 4.
Obtained by shaping the surface. The above-mentioned finely uneven coating layer 5 uses a releasable binder tree 11B to which fine particles 7 having a spherical shape or a shape similar to a sphere are added, so that the center of gravity It is a coating layer that has a surface condition of 0.5 to 2.0% and a surface roughness of 1 to 30 μm. The reason why the center of gravity X of the fine particles 7 is in the above state is that the protrusion of the fine particles 7 must be in the form of outward expansion. The shape of fine particles that can take such a protruding shape is
Generally, it is spherical in shape, but other shapes include ellipses with smooth surfaces similar to spherical shapes, eggplant shapes, and bodies of revolution made by rotating cardioite around an axis of symmetry. The average standard surface of the binder-based paint film refers to the position of the paint film surface where no fine particles 7 are present. The surface gloss value is measured by a specular gloss measurement method according to JIS 28741, and the surface roughness is expressed as the distance from the average standard surface to the top of the fine particles 7. In the present invention, since the suede-like surface 3 is obtained by shaping with the shaping film 6 having the above-described structure, the concave portion 2 exhibits a shape that expands inside compared to the opening, that is, a shape that expands inward. Also, the surface gloss value (751 incidence) on the suede-like surface 3 is 0. 1 to 1.0%, resulting in an excellent super-matte appearance from the surface 3. As the fine particles 7, for example, silica, alumina, calcium carbonate, precipitated barium sulfate, clay, barium silica, penzoguanamine, talc, etc. can be used. The particle size of the fine particles is about 1.3 to 40 μm, preferably about 2 to 10 μm. The amount of fine particles added to the binder resin is adjusted as appropriate depending on the surface gloss value of the coating layer 5, etc. The releasable binder resin is not particularly limited as long as it has good adhesion to the base material 14 and good releasability to the other side (resin layer) when the shaping film 6 is peeled off. ．． The base material 14 of the shaping film 6 includes polyester, polyethylene, polypropylene, polyamide, acrylic, polycarbonate, polyacrylate, polyvinyl chloride, polyethylene terephthalate, polystyrene, polyvinyl fluoride, polytetrachloroethylene, Teflon, polyvinylidene fluoride, and polyvinyl alcohol. , polyether ether ketone, polyimide, polybutylene terephthalate, cellophane, etc. alone, or by laminating these films together as appropriate, or by directly applying the resin to make a laminated film, or with aluminum foil, etc. Examples include composite films, among which polyester films are the most preferred. The resin material for the resin layer 4 may be any material other than thermosetting resin, and thermoplastic resins, electron beam curable resins, etc. can be used. When the resin layer 4 is made of a thermosetting resin, there is a problem in that the thermosetting temperature is high, and the printing sheet is likely to be distorted due to the high heat during curing. Resin layer 4
Any coloring may be applied to enhance the matte effect. The suede-like decorative sheet 9 of the present invention is composed of at least the resin layer 4 as shown in FIG. Further, the decorative sheet 9 is constructed by forming the resin layer 4 with an electron beam curable resin layer 4a, and providing a polyvinyl chloride film 10 on the lower surface of the resin layer 4a, as shown in FIG. In the cosmetic sheet 9, it is preferable to use a matting agent such as silica or alumina as the fine particles 7 and a copolymer resin or mixed resin consisting of thermosetting allyl/urethane as the binder resin. Depending on the structure, there is an advantage that it is easy to obtain a decorative sheet with excellent matting agent retention, matte state, low gloss, surface scratch resistance, abrasion resistance, etc. In the case of the decorative sheet 9 having the structure shown in FIG.
As the electron beam curable resin, polyester, acrylate, urethane acrylate, 2-hydroxyethyl acrylate, neopentyl glycol diacrylate, etc. are preferably used. This decorative sheet 9 is manufactured, for example, by applying an electron beam curable resin to a polyvinyl chloride film 10, overlapping the shaping film 6, and then irradiating the polyvinyl chloride film 10 with the curable resin. By simultaneously curing and adhering to the film IO, and finally peeling off the forming film 6, a decorative sheet having a suede-like surface 3 formed on the cured resin layer surface can be obtained. As shown in FIG. 5, the suede-like transfer foil 11 of the present invention has a suede-like surface 3 having at least the above-described inwardly expanded concave portion 2 on a forming film 6 as shown in FIG. It is constructed by providing a shaping resin layer 4b for shaping. Further, a decorative layer 12, an adhesive layer 13, etc. can be provided on the resin layer 4b, if necessary. According to this transfer foil, after superimposing the resin layer 4b on the object to be transferred so that it is in contact with the object, by peeling off the forming film 6, the resin layer 4b with the suede-like surface 3 formed on the surface is transferred to the object. It can be transferred to the side of the body. As the material of the shaping resin layer 4b, the same material as that of the resin layer 4 can be used. As the decorative layer 12, a general printing ink can be used to form a colored layer or a pattern layer, and in particular, by appropriately coloring the colored layer, the matting effect of the resin layer 4b can be further enhanced. ．．
The adhesive layer l3 can be formed using an adhesive appropriately selected depending on the material of the object to be transferred, and is generally made of a simple material such as acrylic resin, vinyl chloride-vinyl acetate copolymer, rubber resin, thermoplastic urethane resin, etc. Alternatively, a mixed adhesive can be used. Although not particularly shown, a primer layer may be provided next to the resin layer 4b in the transfer foil 1l using the same printing ink used for the decorative layer 12, and by providing this primer layer, it is possible to Post-processing such as shaping of the decorative layer and adhesive layer can be facilitated, and furthermore, it is possible to transfer the resin layer 4b with good smoothness after transfer. Next, the present invention will be explained in more detail by giving specific examples. ! a[L (Production of decorative sheet) Electron beam curable ink (manufactured by Mitsubishi Kaei: PR-202/Mitsubishi Made by Kawei: UV
