Problems solved by technology

[0008] However, when the above-mentioned resin sheet coated with an antifogging agent is subjected to container molding (especially deep drawing molding), its antifogging properties are greatly reduced.
Especially when the coating amount is reduced, container molding (especially deep drawing molding) will lead to a significant decrease in its anti-fog properties, and it is difficult to obtain high anti-fog properties

[0147] Prepare a water-based surface treatment agent (anti-fog treatment agent) so that the solid content ratio of each component (the weight ratio of each component after drying) satisfies the ratio (parts by weight) shown in the table. Here, the concentration of the treatment agent differs depending on the evaluation item, and the concentration of the treatment agent indicates the concentration (% by weight) of the solid content. Next, on the corona discharge-treated surface of a biaxially stretched polystyrene sheet having a sheet thickness of 0.25 mm, a specified amount of a water-based surface treatment agent (anti-fog treatment agent) corresponding to the following evaluation characteristic items was applied, and used Drying was performed at 80°C for 2 minutes with a hot air dryer to form an anti-fog layer.

[0148] The properties (initial properties) of the obtained anti-fog resin sheet and the properties of the sheet obtained by laminating and pressing the anti-fog res...

Abstract

The object of the invention is to obtain an anti-fogging surface treating agent and an anti-fogging resin sheet having excellent anti-fogging property. In terms of 100 parts by weight of base composition, the anti-fogging surface treating agent contains 0.1 to 400 parts by weight (C) of non-ionic surface active agent such as sucrose fatty ester and the like, and / or 0.1 to 20 parts by weight (D) of anionic surface active agent such as paraffin sulfonate and the like. The base composition contains (A) C8-30 fatty amide such as alkanolamide and the like, and (B) water-soluble polymer such as vinyl pyrrolidone polymer. An anti-fogging resin sheet applied to shaping a deep-drawing container can be prepared by coating the surface treating agent on at least one face of the stilbene resin sheet.

Description

technical field [0001] The present invention relates to an antifogging surface treatment agent (antifogging treatment agent) capable of imparting antifogging properties to the surface of a resin sheet or the like, an antifogging resin sheet obtained by treating a resin sheet with the antifogging treatment agent, and A production method thereof, and a container provided with anti-fog properties. Background technique [0002] Hydrophobic synthetic resin sheets such as styrene-based resin sheets used in packaging containers for food and the like have low antifogging properties. If a container made of such a resin sheet is used to store food, etc., due to changes in temperature and humidity, water vapor will adhere to the surface of the container in the form of tiny droplets, causing blurring and reducing transparency. As a result, the visibility of the contents may be reduced. [0003] Then, the method of providing antifogging property to a resin sheet using fatty acid ester ...
