Description

Detailed Description of the Invention 2. Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a colored mirror and a method for manufacturing the same. More specifically, it is a colored mirror for high-mix, low-volume production in which a hard base material layer formed on one or both sides of colorless transparent glass is provided with a colored coating ffQ5, and a coating layer is formed on either surface, and its manufacture. Regarding the method.

(Prior art) Conventionally, colored mirrors have been made by coating a colored material with a metal reflective film or backing paint, or by providing a colorless transparent material with a colored synthetic resin film and then applying a metal reflective film or backing paint. , In addition, a metal colored film is fused to a transparent metal material, and a backing paint is applied with or without a metal reflective film, and in addition, vacuum vapor deposition on a colorless transparent material,
Those subjected to metal vapor deposition by sputtering, ion blasting, etc. are known.

However, the methods described above (such as glass materials colored by mixing paint or pigments, or colorless transparent materials coated with metal vapor deposition) are disadvantageous in terms of productivity and cost, and the color range is limited. However, products made of colorless and transparent materials coated with colored synthetic resin coatings have the disadvantage of inferior product stability.In this way, products that use conventional colored materials or those that have been colored Various problems were observed in terms of cost, productivity, quality stability, workability such as cutting, fashionability, etc.

(Problems to be Solved by the Invention) As described above, the range of colors available for colored mirrors using conventional colored glass plates is limited, and colored glass is quite expensive and also has problems in terms of quality. However, it was not suitable for high-mix, low-volume production.

The present invention was completed as a result of various studies in order to solve these conventional problems, and the present invention has a colorless transparent material having compatibility with the glass plate and dyeability on one or both sides of the slope. A colored mirror comprising a mirror material provided with a hard base layer made of a resin composition, and a coating layer formed on either surface of a colored coating layer formed by dyeing the mirror material, and a method for manufacturing the same. The purpose is to provide Another object of the present invention is to obtain a colored mirror that has clear hue reflectivity, is excellent in productivity and quality stability, and can be produced at low cost for high-mix, low-volume production.

(Means for solving problems) Hereinafter, the configuration of the present invention will be explained based on illustrated embodiments.

FIG. 1 is a schematic cross-sectional view of a glass plate with a colored coating layer provided on both sides, and FIG. 2 is a schematic cross-sectional view of a glass plate with a colored coating layer provided on one side. In FIG. 1, a colored mirror body l according to the present invention is shown.
A hard base material layer 4 is layered on both sides of the glass plate 2 by a dipping method or the like using a resin composition that has affinity and hardness with the transparent uncolored glass plate 2 and is dyeable. After the mirror material 3 has been formed, a colored film layer 9 is provided by dyeing the mirror material 3 using a disperse dye or the like, and then a reflective liquid solution is coated on one side of the mirror material 3 by a conventional method. Following the film 5 and the copper coating 6, a coating layer 8 consisting of a backstop coating 7 is provided.

Next, in FIG. 2, a resin composition having an affinity with the glass plate 2, the necessary hardness, and dyeability is sprayed or roll coated on only one side of the transparent uncolored glass plate 2. After applying a layer to the hard base material layer 4 by flow coating or the like, dyeing is performed to form a mirror material 3 provided with a colored coating layer 9, and then the surface of the coating layer 9 is coated in vacuum by a metal vacuum evaporation method. The structure is such that a coating layer 8 made of a metal vapor-deposited film 10 is provided by vapor deposition. Moreover, when forming the hard base material layer 4 on one side, it can also be set as the structure which provided the coating layer 8 on the other one side, if necessary.

In the present invention, the resin composition layered on the transparent uncolored glass plate 2 needs to have affinity with the glass plate 2, dyeability, and surface hardness suitable for the mirror material 3. For example, those whose main component is a polysiloxane resin composition such as a carbon functional silane resin made of a hydrolyzed condensate of γ-glyndoxypropyltrimethoxysilane or γ-methacryloxypropyltrimethoxysilane, etc. The hard base material layer 4 is formed by applying the layer by dipping, spraying, roll coating, flow coating, etc., setting, baking, and cooling.

In addition, for dyeing the mirror material 3 on which the hard base material layer 4 is formed,
The dye is appropriately selected depending on the desired hue.

For these dyeings, it is appropriate to use disperse dyes, and if necessary, dyeing aids and the like may also be used in combination. When the colored film layer 9 is formed, under the same conditions, when the hard base material layer 4 is thick, the coloring becomes relatively dark;
If it is thin, a light coloring will be obtained.

The thickness of the hard base material layer 4 is suitably in the range of 1 μm to 20 μm, preferably in the range of 5 μm to 20 μm. If the thickness is less than the above range, the effect of the colored coating layer will be poor, and if the thickness exceeds this range, cracks will easily occur on the membrane surface, and it will also be unfavorable in terms of product processing such as cutting and drilling.
