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. ...
