(Field of Industrial Application) The present invention relates to a laminated glass used as an automobile window glass in which a ceramic color is formed on the peripheral edge. (Prior Art) Laminated glass used as automobile window glass is made by bonding an outer glass plate 10 and an inner glass plate 11 with an interlayer film 12 interposed therebetween, as shown in FIG. This is done using adhesive 14 or the like. A ceramic collar 15 is formed on the peripheral edge of the indoor side surface of the inner glass plate 11 to hide the attachment portion to the window frame 13 from the outside. Here, since the interlayer film 12 loses its adhesive strength when it comes into contact with moisture, the interlayer film is likely to peel off at the edge portions of laminated glass. In recent automobiles, there is a tendency to make the molding of the window frame portion smaller, and the peeled portion becomes noticeable from the outside. Therefore, it is conceivable to form the ceramic collar 15 on the inner and outer surfaces of the outer glass plate 10, that is, on the outer side of the interlayer film 12. However, if a method is adopted in which ceramic paste is applied to the inner surface of the outer glass plate and the ceramic paste is fired at the same time as the outer glass plate and the inner glass plate are bent and formed by bearing, the ceramic paste is heated due to lack of oxygen. The resin content cannot be sufficiently decomposed by heat, and a large amount of carbon is incorporated into the collar, resulting in a gray color and poor firing. Therefore, JP-A-55-67548 or JP-A-62-
As disclosed in No. 30643, after applying ceramic paste to the outer glass plate, the outer glass plate and the inner glass plate are exchanged, and the ceramic paste portion is not covered with the inner glass plate, and bending and forming are performed. or Japanese Patent Application Publication No. 1983
As disclosed in No. 72548, after applying ceramic paste to a flat outer glass plate and once firing the ceramic paste, the outer glass plate and the inner glass plate are placed on a ring mold in a separate process, and then their own weight is applied. A method is known in which the material is bent and formed. (Problem that the invention aims to solve) If the outer glass plate and the inner glass plate are reversed and bent and formed, the resin content in the ceramic paste can be sufficiently broken down, but the bending shape is complicated and the curvature is large. In some cases, when laminated glass is used, gaps are likely to occur between the glass plates. Furthermore, once the ceramic paste has been fired, bending the glass plate requires two heating steps, which is disadvantageous in terms of production efficiency. (Means for Solving the Problems) In order to solve the above problems, the present invention applies ceramic paste to the inner surface of the outer glass plate, overlaps the inner glass plate on this surface, and bends it and bakes it. , the thickness of the ceramic color after firing is 15μ or less, and the resin content in the ceramic paste applied to the inner surface of the outer glass plate of the laminated glass is
The content was set at 0.2-1.4wt%. (Function) 0.2 to 1.4wt% resin content in ceramic paste
Therefore, even if the outer glass plate and the inner glass plate are paired and bent on a ring mold so that the ceramic paste (already dry) is sandwiched between them, the paste will be damaged by the heating during bending. The resin content is fully decomposed by firing. (Example) An example of the present invention will be described below based on the accompanying drawings. FIG. 1 is a cross-sectional view of the main parts of the laminated glass according to the present invention.
The inner peripheral edge of the inner glass plate 3 is fixed to the window frame 5 with an adhesive 6. A ceramic collar 7 is formed on the periphery of the inner surface of the outer glass plate 2. Ceramic Color 7 is formed by firing a ceramic paste, which contains 55-65 wt% of low melting point lead glass, 15-25 wt% of pigment,
It consists of 15 to 20 wt% of vehicle, and the vehicle consists of oil such as terpineol and resin. Conventionally, the proportion of resin is 2 to 4 wt%.
However, in the case of the present invention, the proportion of resin was set to 0.2~
The content is 1.4wt% (preferably 0.2 to 0.8wt%).
In other words, 1 to 7 wt% (preferably 1 to 4 wt%) of resin is added to the oil to form a vehicle, and the breakdown is 7 wt% of ethyl cellulose (preferably 1 to 4 wt%).
4wt%) or less, rosin 5wt% (preferably 3wt%)
Below, acrylic resin 5wt% (preferably 3wt%)
It is as follows. The reason why the proportion of resin is set to 0.2 to 1.4 wt% to the whole paste is that if it exceeds 1.4 wt%, it will not be sufficiently decomposed by heating.
This is because the ceramic color, which is less than 0.2wt%, becomes faded. Further, it is preferable to use an acrylic resin which can be self-decomposed as the resin. To manufacture the above laminated glass 1, as shown in FIG. 2A, a ceramic paste 7a is applied to the inner surface of the flat outer glass plate 2 and dried, and then as shown in FIG. 2B, the outer glass plate 2 and the inner glass plate 3 are placed one on top of the other with the ceramic paste 7a sandwiched between them, and then, as shown in FIG. The ceramic paste 7a is bent and formed under its own weight, during which time the ceramic paste 7a is fired to form the ceramic color 7, and then an interlayer film 4 is formed between the outer glass plate 2 and the inner glass plate 3.
This is placed in an autoclave, and the outer glass plate 2 and the inner glass plate 3 are bonded via the intermediate film 4 as shown in FIG. 2D. Next, the thickness of the ceramic color 7 after firing and the quality of firing (judged by color, ○...good, ×...poor) are shown in the following [Table].

ことができる。[Table] As is clear from this [Table], the thickness of the ceramic color 7 after firing is preferably 15 μm or less. The drying temperature is 150 to 400℃ (preferably
150-250℃). (Effect of the invention) As explained above, according to the invention, the resin content in the paste that becomes the ceramic color can be reduced by 0.2 to 1.4wt.
%, so it decomposes sufficiently even in an atmosphere with little oxygen, so the paste can be applied to the inner surface of the outer glass of the laminated glass, and the inner glass can be stacked on this surface to perform bending, forming and firing, so that normal color development can be achieved. The peeled part of the interlayer film can be hidden using ceramic color. In addition, the resin content in the paste is 0.2wt% to 1.4wt%.
By forming the ceramic color with a thickness of 15 μm or less after firing, a ceramic color with normal color development can be obtained in a process performed simultaneously with bending and forming.
