Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a printing surface formed on a satin surface to decorate the surface of the glasses.

[0002]

[Prior art]

 The eyeglass frame can be hung on the face by fitting the lens to the rim formed on the front part. Therefore, the eyeglass frame needs to be light and hard to get tired, and a recent metal eyeglass frame is often made of a light material having excellent spring properties such as titanium. On the other hand, eyeglasses are worn on the face, so fashion is required, and various decorations are given as well as mere functionality.

[0003] This is not limited to a metal eyeglass frame, but is the same for a resin frame. For example, the surface of the eyeglass frame is often decorated by plating, painting, or printing. In addition, other decorative parts, such as diamonds and rubies, may be installed.

[0004] Conventionally, a decorating method in which the surface of the spectacle frame has a matte surface has been preferred. FIG. 3 shows a case in which the outline of a decorating process having a matte surface is illustrated. (1) The surface (a) of the eyeglass frame or its parts is shown. (2) A case in which a tape (b) is pasted on the surface (a) to perform masking. Here, the masking tape (b) is formed in various shapes, but it is difficult to make a small and thin tape.

[0005] (3) is a sanding process in which the surface (a) is roughened to leave a pear surface (c) except for the portion where the tape (b) is adhered. (4) This is a case where the attached tape (b) is peeled off. Therefore, the frame surface (a) exists only at the mark where the tape (b) has been removed, and the other surface is a matte surface (c). Of course, there is a very slight step between the surface (a) and the matte surface (c), but a pattern, a figure, or a character is completed on the matte surface (c).

(6) This is a case where a plating layer (d) is formed by plating the entire surface. The entire eyeglass frame surface will be covered by the plating layer (d), but through the plating layer (d), patterns, figures, etc. will be formed by the combination of the matte surface (c) and the surface (a). Here, there are other ways to form a matte surface on the frame surface.However, in order to form a pattern or figure, a masking tape must be attached and sanded in any case. Requires a lot of man-hours.

By the way, a pattern, a figure, and the like are formed on the frame surface by the matte surface (C) shown in FIG. It is impossible to make a masking tape (c) for masking (a), which has a fine and complicated shape or a slender line, and to stick it. At the same time, even when masking fine and complex shapes and thin lines, patterns and figures cannot be formed by sanding.

[0008] In a pattern or figure formed by such a conventional method, the width dimension is limited to about 1 mm, and is impossible if the width dimension is as small as 0.1 mm. In addition, since steps such as the pasting of a tape (b) and sanding are required, the number of working steps is increased and the cost becomes extremely high.

[0009]

[Problems to be solved by the invention]

 As described above, the patterns and figures provided with the conventional masking process have the above-mentioned problems. The problem to be solved by the present invention is this problem, and provides a decorative printing surface of a spectacle frame that can form fine figures and patterns in a simpler manner.

[0010]

Means for Solving the Problems The decorative printing surface of the eyeglass frame according to the present invention forms the same matte surface as when sanded by printing. That is, a predetermined ink is printed to form a pattern, a figure, a character, or the like, which is dried. Drying can be performed by forced heating or natural drying at room temperature, but it is selected in consideration of the material and efficiency of the eyeglass frame. The ink layer forms a pattern, a figure, or a character, and a means for transferring the image with a pad is generally used.

Here, the ink that forms the ink layer contains very fine beads. By printing this ink on the surface of the frame and then drying it, a matte surface without gloss is obtained. In other words, the present invention is a technology for easily forming a matte surface by printing.

More specifically, it comprises a 20-30% solution of cyclohexanone, a 20-30% solution of ethyl acetate, a 40-50% solution of xylene, and beads composed of ultrafine particles as a mat material. Basically, an ink composed of cyclohexanone, a mat material, and ethyl acetate may be used. The weight ratio is such that ethyl acetate is mixed at a ratio of 10 to 20% with respect to the mixed weight of the cyclohexanone and the mat material.

[0013] The ratio of cyclohexanone and matte material is free. Further, if necessary, a solvent of 40 to 50% of xylene may be mixed at a ratio of 2 to 3%. Among the above-mentioned ink components, beads, which are mat materials, are components that make the frame surface a matt surface. Then, the ink is transferred to the frame surface and then dried. In the case of forced heating and drying, the heating is performed at 110 to 115 ° C. for about 20 minutes. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

【Example】

 FIG. 1 is an embodiment showing an outline of a process of forming a decorative printing surface according to the present invention. (1) shows the front surface 1 of the metal eyeglass frame. The place where printing is performed is not particularly limited, and may be an outer surface of a crane or a front surface. (2) is a case where plating is performed on the surface 1 of the eyeglass frame to form a plating layer 2. The plating is generally applied to the entire eyeglass frame so that the plating layer 2 is formed on the entire surface. Here, the specific method of plating is not limited, and painting may be performed instead of plating.

(3) The ink layer 3 for forming a predetermined pattern, figure, or character by printing on the plating layer using ink. This printing is generally performed by transfer, so that even very fine patterns, figures, or characters can be accurately formed, and even long and thin lines can be formed without interruption. For example, a line having a width of 0.1 mm can be formed.

Incidentally, the ink used in the printing of the present invention comprises a solvent of 20 to 30% of cyclohexanone, a solvent of 20 to 30% of ethyl acetate, a solvent of 40 to 50% of xylene, and a mat material. This ink is used to transfer onto the plating layer 2. The cyclohexanone functions as an adhesive, and the ethyl acetate functions as a strengthening agent to aid adhesion. The mat member is formed of beads, for example, glass beads, gold beads, or the like, and is formed of ultra-fine particles of 3 μm to 5 μm. Xylene is a component for preventing bubbles and the like from remaining on the printed surface.

Here, the mixing ratio of cyclohexanone and beads as matting material is free, but ethyl acetate is mixed in a ratio of 10 to 20% with respect to the total weight of the above cyclohexanone and beads as matting material. You. If the glasses frame is made of resin, 10% is suitable, and if it is made of plated metal, 20% is suitable.

Here, since the specific method of the transfer is well known, detailed description thereof will be omitted. However, in general, a pattern, a figure, a character, or the like is copied on the pad surface using a pad. This pad is transferred to the plating layer 2 provided on the surface of the frame. Thereafter, the ink layer 3 is heated and dried at a high temperature, and then heated and dried at a temperature of 110 ° C. to 115 ° C. for about 20 minutes, so that the ink layer 3 is fixed so as not to be separated from the plating layer.

The mat material composed of beads of the ultrafine particles, which are components in the ink, is dried to form a matte surface sanded on the surface. FIG. 2 shows the case where the ring-shaped ink layer 3 is transferred to the surface. The outer portion 4 and the center 5 of the ring are the surface of the mech layer 2, and the ring portion shows the color of the ink used. When presented, it becomes a matte pear ground. In other words, the printing of the present invention is a decorative pattern in which a printing pattern or figure is formed on the matte surface, and is formed by a combination with an unprinted plating layer.

By the way, in the present invention, a spectacle frame made of resin is also a target, and a pattern, a figure, and the like of a matt surface can be formed by directly transferring to a surface of the resin frame. Also, the printing means is not limited to transfer, and silk printing can be adopted, and a printing method suitable for the shape of the eyeglass frame can be adopted. As described above, the printed surface of the present invention has the following effects.

[0021]

【The invention's effect】

 The printing surface of the present invention is formed in three steps: a plating or painting process, a printing process such as transfer, and a drying process. The printing surface is very simple compared with the case of processing a conventional satin surface pattern. The production cost is lower. Needless to say, due to the small number of man-hours, the delivery period is shortened, and the cost can be reduced. In particular, the absence of traditional masking and sanding processes can provide significant benefits.

In addition, in the present invention, since there is no masking or sanding process, very fine patterns, figures, and characters can be formed. I can do it. Since printing is performed by transfer, there is no problem even if the surface of the frame is curved, and it is not affected by the material of the frame.
