Embodiment

[0482] Hereinafter, the present invention is described in more detail by means of examples, but the present invention is not limited to these examples.

[0483] It should be noted that a biaxially stretched polyethylene terephthalate film (trade name: "MRN38", manufactured by Mitsubishi Chemical Polyester Film) having a thickness of 38 μm on which a silicone-based release treatment was performed was used Each cover film and substrate film were used for each of the following examples.

[0484]

[0485] The following flame retardancy of the polymer sheet was evaluated.

[0486] pass figure 2 The evaluation of flame retardancy was carried out in the horizontal burning test shown in. figure 2 The measurement method is shown. Each polymer sheet was cut into a piece having a size of 5 cm x 12 cm, which was then evaluated. Care should be taken to peel off the cover films on both sides of each polymer sheet.

[0487] In each physical functional flame-retardant polymer sheet a...

Synthetic example 1

[0546] (Synthesis Example 1) (Preparation of Slurry (b-1))

[0547] 50 parts by weight of isobornyl acrylate, 50 parts by weight of lauryl acrylate, 0.1 part by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by Ciba Specialty Chemicals Inc.) and 0.1 part by weight of a photopolymerization initiator (trade name : "IRGACURE184", manufactured by Ciba Specialty Chemicals Inc.) was stirred in a four-necked separable flask equipped with a stirrer, a thermometer, a nitrogen gas introduction tube, and a cooling tube until the mixture became homogeneous. Thereafter, bubbling with nitrogen gas was performed for 1 hour to remove dissolved oxygen. Thereafter, UV light was applied from outside the flask by using a black light lamp to perform polymerization. At the point when a moderate viscosity is obtained, the lights are turned off and nitrogen sparging is stopped. Thus, a partially polymerized slurry composition having a polymerization rate of 7% wa...

[0548] (Synthesis Example 2) (Preparation of Slurry (a-1) Containing Layered Inorganic Compound)

[0549] 30 parts by weight of layered clay mineral (trade name: "LUCENTITE SPN", manufactured by Co-op Chemical Co., Ltd., shape: flat plate) was added to 100 parts by weight of cyclohexyl acrylate, 0.2 parts by weight of 1, 6-hexanediol diacrylate, 0.2 parts by weight of a photopolymerization initiator (trade name: "IRGACURE651", manufactured by Ciba Specialty Chemicals Inc.), and 0.2 parts by weight of a photopolymerization initiator (trade name: "IRGACURE184", manufactured by Ciba Specialty Chemicals Inc.), and then the whole was allowed to stand at room temperature (25° C.) for 24 hours. Thus, a monomer mixture (cloudy) to which layered clay minerals have been added is obtained. Thereafter, the layered clay mineral-added monomer mixture was irradiated with ultrasonic waves from an ultrasonic disperser (manufactured by NIPPON SEIKI CO., LTD.) at an irradiation intensity of 500...
