Problems solved by technology

In the unexposed part, it is difficult to adhere the coloring material with good adhesion, and it is easy to cause partial defects, poor shape and poor adhesion of the coloring pattern.
In this way, dust and fingerprints are not easy to adhere to the surface of the laminate before the coloring layer is laminated, and the coloring material is glued to the unexposed part with good adhesion. These are opposite necessary characteristics, and it is difficult to achieve both.

[0217] Examples 1 to 7, Comparative Examples 1 to 6 (Manufacture of Resin Composition, Molding Laminate, and Cured Laminate Molded Article)

[0218] The resin composition shown in Table 2 was prepared, and the resin composition was coated on an acrylic resin plate (trade name: Comoglass Co., Ltd. Kuraray) with a length of 30 cm, a width of 21 cm, and a thickness of 2 mm, so that the thickness of the coating film reached 10 μm, ( Comparative Example 5 was not coated), and dried at 80° C. for 30 seconds to obtain a laminate for molding. After heating the obtained laminated body for molding at 190° C. for 3 minutes, vacuum molding was performed to obtain a box shape with a length of 20 cm, a width of 10 cm, and a height of 10 cm (maximum surface stretching ratio of 25 times), and then by UV irradiation (irradiation amount 2J, HTE-3000B, manufactured by HI-TECH Corporation) to obtain a cured laminated molded body. Table 2 shows the measurement and evaluation results of the resin ...

Abstract

The present invention provides an active energy ray-curable resin composition that can be used in an uncured state after film formation, has a short curing time, can be molded, and can provide a hard coat layer with high hardness. Active energy ray-curable resin composition comprising a vinyl polymer having an alkoxysilyl group on a side chain and a photoacid generator, and having a glass transition temperature in an uncured state of not less than 15°C and not more than 100°C , more than 90% by mass of the Si atom-containing compound or the Si atom-containing compound unit is represented by the following structural formula 1, (R1)nSi(OR2)4-n (structural formula 1), in the structural formula 1, R1 represents the component (a) A unit in the main chain of the vinyl-based polymer, a residue bonded to the main chain, a polymerizable group capable of forming the unit and / or the residue, or an alkyl or aryl group that may be substituted. R2 represents an alkyl group having 1 to 5 carbon atoms. n represents an integer of 1 to 3.

Description

technical field [0001] The present invention relates to an active energy ray-curable resin composition, a laminate in which an active energy ray-curable resin layer is laminated, a method for producing a cured laminate in which an active energy ray is irradiated to the laminate, and an application thereof. The cured laminate obtained by this manufacturing method. Background technique [0002] Compared with glass, plastic materials have the characteristics of excellent impact resistance, easy molding into a curved shape, and light weight. However, damages of various sizes and depths are easy to form on the surface. In addition, once stains enter the damage, it will It is difficult to remove, so there is a problem of easy contamination. For plastic moldings, therefore, there is an urgent need to improve the scratch resistance of the surface thereof. [0003] As a method of simply imparting a hard coat function to a plastic molded body with a curved surface, it has been propo...
