Problems solved by technology

[0007] However, in the above-mentioned decorative sheet, a plurality of layers is formed by printing special ink on the synthetic resin sheet, so it is difficult to manufacture and the manufacturing cost is high compared with the conventional synthetic resin sheet used for folders.

Embodiment 1

[0057] Table 1 shows the evaluation results of the color rendering and shielding properties of the synthetic resin double-layer sheet 11 obtained by laminating the first synthetic resin layer 12 and the second synthetic resin layer 13 having different thickness ratios and integrally molding them.

[0058] In addition, in the synthetic resin double-layer sheet 11, the first synthetic resin layer 12 contains color pigments and is in a colored and transparent state, and the second synthetic resin layer 13 contains white pigments and is in a state of shielding properties.

[0059] [Table 1]

[0060]

[0061] In sample No. 1, the ratio of the first synthetic resin layer 12 to the second synthetic resin layer 13 was 1:9, and when integrally molded, the first synthetic resin layer 12 was thin, so deformation occurred, and molding could not be ensured.

[0062] In the samples of sample number 2 to 4, the ratio of the first synthetic resin layer 12 to the second synthetic resin laye...

Embodiment 2

[0067] Table 2 shows the shielding properties of the synthetic resin double-layer sheet 11 that is integrally molded by laminating the first synthetic resin layer 12 and the second synthetic resin layer 13 with different thickness ratios, and further having recesses 14 on the surface of the first synthetic resin layer 12. The evaluation result of the shadow effect.

[0068] In addition, in the synthetic resin double-layer sheet 11, the first synthetic resin layer 12 contains color pigments and is in a colored and transparent state, and the second synthetic resin layer 13 contains white pigments and is in a state of shielding properties.

[0069] In addition, the surface of the first synthetic resin layer 12 is mirror-finished.

Abstract

The invention provides a synthetic resin double-layer sheet which can be manufactured easily and inexpensively and has well color rendering and shielding property. The inventive synthetic resin double-layer sheet is integrally formed by laminating a first synthetic resin layer (12) and a second synthetic resin layer (13), the first synthetic resin layer (12) is formed by synthetic resin colorized by color pigments and having transparency, the second synthetic resin layer (13) is formed by synthetic resin which is colorized by the color pigments with transparency and which has shielding property. It is possible to improve the color rendering based on the first synthetic resin layer (12) and the first synthetic resin layer (12) based on the second synthetic resin layer (13) by laminating the two layers of synthetic resins. Furthermore, the color rendering of the first synthetic resin layer (12) can be enhanced once white pigment having the shielding property is used to colorize the second synthetic resin layer (13). Besides, on account of the integral forming that is implemented only by laminating the first synthetic resin layer (12) and the second synthetic resin layer (13), the invention can be manufactured easily and inexpensively.

Description

technical field [0001] The present invention relates to a synthetic resin two-layer sheet formed of a sheet having transparency and a sheet having opacity. Background technique [0002] The thickness of the synthetic resin sheet used for folders such as transparent folders is preferably 0.4 mm to 2.0 mm. However, synthetic resins having a thickness in this range do not have shielding properties, and synthetic resin sheets cannot ensure shielding properties. Therefore, in order to improve the synthesis The color development and masking properties of the resin sheet are colored by making the synthetic resin sheet contain a mixture of color pigments other than white and white pigments having masking properties. [0003] Here, the synthetic resin sheet contains a white pigment in order to improve the hiding property, and due to the presence of the white pigment, the color formed by the color pigment other than white becomes cloudy, and the color rendering property deteriorates. ...
