性を損なうことが多く、効果の低い防曇剤は高添加量に
すると吹き出しによる透明性の低下が懸念される。[Prior art and its problems] Conventional methods for imparting antifogging properties to plastic sheets include a kneading method and a coating method. The kneading method is a method in which an antifogging agent is mixed with a base compound and made into a sheet.However, antifogging agents with high antifogging properties often impair the transparency of the sheet, and antifogging agents with low effectiveness often impair the transparency of the sheet. If the amount of fogging agent added is high, there is a concern that the transparency will decrease due to bubbling.

が、その効果を失ってしまう。Coating agents used in the coating method include higher alcohol sulfate esters, sulfated monocrycerides, and polyethylene glycol fatty acid esters, but even if they exhibit good antifogging properties immediately after application, most of them lose their properties when subjected to secondary molding. It loses its effectiveness.
従って、プラスチック系透明シートで二次加工後も安定
な防曇性を示すものが強く求められていた。Therefore, there has been a strong demand for a plastic transparent sheet that exhibits stable antifogging properties even after secondary processing.
