2. Description of the Related Art Conventionally, as a transparent face plate placed on the front side of display samples such as cans in vending machines, or a face plate for outdoor signboards used as large-sized signboards used at gas stations, etc. Since it is excellent in workability such as punching, thermoforming, etc., and weather resistance, one made of an impact-resistant acrylic resin is often used. However, those made of acrylic resin have a problem that they are easily burned and easily cracked.

However, when a polycarbonate resin is used, predrying is required when performing vacuum forming, which is often used for manufacturing a face plate for a signboard, and this requires a lot of time. Therefore, there is a problem that productivity is reduced. In addition, there is a problem that the suitable temperature for thermoforming is high, which in turn lengthens the molding cycle. Furthermore, since the masking melts, it is difficult to form the mask with the masking attached, and in addition, the face plate is often scratched during handling such as removing the masking after thermoforming.

On the other hand, it is possible to use a polyester resin as a solution to the above problems of the acrylic resin and the polycarbonate resin.
The polyester resin has a fatal defect that it is inferior in heat resistance such that it is easily deformed when exposed to sunlight outdoors. In particular, it becomes noticeable in the case of black printing. Due to such poor heat resistance, it is difficult to use the polyester resin as a substitute material for the acrylic resin or the polycarbonate resin.

Since the mixing ratio of the polyester resin and the polycarbonate resin is regulated within a specific range, it is possible to have both excellent moldability and excellent heat resistance. Moreover, since both resins are resins that are difficult to burn, sufficient flame retardancy can be provided. Furthermore, since the glycol-based polycondensation component constituting the polyester resin contains 40 mol% or more of 1,4-cyclohexanedimethanol, the refractive index of the polyester resin is extremely close to that of the polycarbonate resin. In addition to excellent transparency, the compatibility of both resins is also very good, so that excellent impact resistance is secured. In addition, since a terephthalic acid-based component is used as the dicarboxylic acid-based polycondensation component,

Above all, it is preferable that the proportion of the terephthalic acid-based component in the entire dicarboxylic acid-based polycondensation component is 95 mol% or more. If it is less than 95 mol%, mechanical strength, heat resistance and chemical resistance are lowered, which is not preferable. For example, mechanical strength, heat resistance, and chemical resistance are markedly reduced when more than 5 mol% of a commonly used dicarboxylic acid polycondensation component such as isophthalic acid is used in combination. Above all, it is particularly preferable that the content of the terephthalic acid-based component is 97 mol% or more based on the entire dicarboxylic acid-based polycondensation component.

On the other hand, as the glycol-based polycondensation component,
It is necessary to use 40 mol% or more of 1,4-cyclohexanedimethanol. That is, the proportion of 1,4-cyclohexanedimethanol in the entire glycol-based polycondensation component needs to be 40 mol% or more. If it is less than 40 mol%, the transparency is lowered and, at the same time, the compatibility with the polycarbonate resin is lowered and mechanical strength such as impact strength is lowered. Above all, 1, in the entire glycol-based polycondensation component
The proportion of 4-cyclohexanedimethanol is 50 mol%
The above is preferable, and in this case, since the refractive index of the obtained polyester resin is extremely close to the refractive index of the polycarbonate resin, excellent transparency can be obtained, and the compatibility of both resins is also very good. As a result, excellent impact resistance can be ensured. In addition,
Although 1,4-cyclohexanedimethanol has two isomers, a cis type and a trans type, any of them may be used.

In the present invention, the mixing weight ratio of polyester resin / polycarbonate resin is 60 / 40-80.
It must be in the range of / 20. If the mixing ratio of the polycarbonate resin is smaller than the above range, the heat resistance becomes insufficient. For example, it becomes difficult to prevent the occurrence of deformation under hot weather in summer. On the other hand, when the mixing ratio of the polycarbonate resin is larger than the above range, a preliminary drying step is required to prevent foaming in thermoforming such as vacuum forming, which requires a lot of time and lowers productivity.
In addition, the molding cycle becomes longer and the moldability is reduced. Above all, the mixing weight ratio of polyester resin / polycarbonate resin is preferably in the range of 65/35 to 75/25.

INDUSTRIAL APPLICABILITY As described above, the transparent face plate for outdoor use of the present invention has excellent moldability and excellent heat resistance because the mixing ratio of the polyester resin and the polycarbonate resin is defined in a specific range. be able to. Further, since it is not necessary to perform preliminary drying before thermoforming, the production efficiency is good and the cost is low. Further, since both resins are flame-retardant resins, they have sufficient flame retardancy. Furthermore, as a glycol-based polycondensation component constituting the polyester resin, 1,
Since it contains 40 mol% or more of 4-cyclohexanedimethanol, the refractive index of the polyester resin is very close to that of the polycarbonate resin, and excellent transparency is obtained, and the compatibility of both resins is also high. It becomes a very good product and excellent impact resistance can be secured. In addition, since a terephthalic acid-based component is used as the dicarboxylic acid-based polycondensation component, excellent mechanical strength and chemical resistance can be imparted, and heat resistance can be further improved.
