Problems solved by technology

[0008] However, in the conventional laminated films mentioned above, it is difficult to ensure processability and originality while ensuring the above-mentioned coating properties.
That is to say, conventional laminated films have the following problems: if the focus is on ensuring the coating properties, the workability and originality will be reduced, and if the workability is emphasized, it will be difficult to ensure the coating properties and the originality
However, if emphasis is placed on flexibility as mentioned above, it is difficult to ensure the coating properties of the laminated film
In addition, there is a problem that it is difficult to ensure the originality of the laminated film due to the disorder in the arrangement of the glossy material, etc.
[0010] Therefore, conventionally, there has been a problem that, if the workability of the object to be coated with a laminated film is to be secured, it is impossible to obtain a coating of a level higher than that achieved by the above-mentioned spray coating method, dip coating method, etc. Character and originality

[0118] Hereinafter, the present invention will be described with reference to examples and comparative examples, but the present invention is not limited thereto.

[0119] In addition, the measurement of the weight-average molecular weight Mw, the calculation of the glass transition temperature, the calculation of the hydroxyl value (OHV), the evaluation of the transparent layer (B), the evaluation of the laminated film, the acrylic polymer (B1 ) manufacture.

[0120] [Measurement of weight average molecular weight Mw]

[0121] The weight-average molecular weight Mw of each polymer was measured in terms of standard polystyrene using gel permeation chromatography. And, use Gelpack R400, R450, R400M (all from Hitachi Chemical Industry Co., Ltd.) as a column, use tetrahydrofuran as an eluent, measure with Hitachi L6000 type high-speed liquid chromatography, use Hitachi L3350 type differential refractometer as Detector. In addition, the measurement conditions are: column temper...

Abstract

The laminating film has a clear layer (B) comprising an acrylic polymer (B1). The acrylic polymer (B1) has long-side-chain double bonds derived from a long-chain unsaturated carboxylic acid having a molecular weight of at least 150 and short-side-chain double bonds derived from a short-chain unsaturated carboxylic acid having a molecular weight of below 150. The weight-average molecular weight of the acrylic polymer (B1) is in the range of 50,000 to 500,000. To provide a laminating film which has design properties and coating film performances at least equivalent to those realized by e.g., spraying or dipping, exhibits a high ability to follow the shape of a molding, and realizes good decoration on the molding.

Description

field of invention [0001] The present invention relates to a laminated film used when modifying a shaped article by a film modification method. Background of the invention [0002] Molded products such as metal products, plastic products, inorganic products, and wood products are sometimes subjected to a finishing treatment to form a coating on the surface of the molded product for the purpose of imparting durability and artistic characteristics including color. Since the material and shape of the finished molded article (hereinafter referred to as the object to be painted) are various, in order to form a coating on the concave part and gap of the object to be painted easily, spraying method and dip coating method can be obtained. a wide range of applications. [0003] In general, many coating layers formed by coating an object to be coated are laminated films obtained by laminating a plurality of layers. For example, the above-mentioned laminated film is composed of a bas...
