Problems solved by technology

[0004] On the other hand, in recent years, the wall surface in the house, especially in the bathroom, toilet or kitchen, the chance of using coloring agents such as strong irritating detergents such as acids and hair dyes has increased. Deterioration and deterioration of the wall surface may occur, as well as discoloration and staining
There is no doubt that deterioration and deterioration are undesirable phenomena, and once discoloration occurs, the original color cannot be restored. In addition, if staining occurs, it will become more difficult to return to the original color as time goes by. This is also undesirable. The cause of the phenomenon

Embodiment 1

[0090] The photocurable resin composition C1 prepared above was coated on the upper surface of a substrate made of FRP (DIC Matt (registered trademark) 2415, manufactured by DIC Kako Inc.) to a thickness of 20 μm. Next, UV irradiation (1000mW / cm 2 , 4000mJ / cm 2 ) to cure the photocurable resin composition C1 to obtain a functional panel.

Embodiment 2～6

[0092] A functional panel was obtained in accordance with Example 1 except that various photocurable resin compositions C2 to C6 prepared above were used.

Abstract

Provided is a functional panel which can withstand the damage, alteration, discoloration, and dyeing caused by acid-containing detergents or dyeing materials such as hair dyes, which are coming to be used more frequently in recent years.  The functional panel is characterized by comprising: a coating layer having a glass transition temperature of 50°C or higher obtained by curing a photocurable resin composition obtained from a photopolymerizable monomer having a solubility parameter (SP value) of 20.0 (J / cm3)0.5 or less and a photopolymerizable oligomer; and a base layer.

Description

technical field [0001] The present invention relates to a functional panel having improved chemical resistance and staining resistance by using a photocurable resin composition containing a specific photopolymerizable monomer. Background technique [0002] A functional panel as a building material is a member arranged as a wall surface, a floor surface, or a ceiling wall surface of a building, and various functions such as sound insulation effect and humidity control are provided according to the location where it is arranged. Especially when it is used as a member for a water place such as a bathroom, a toilet, or a kitchen in a house, it is required to have various characteristics such as water resistance and moisture resistance that can withstand a more severe use environment. [0003] For example, Patent Document 1 discloses a decorative board in which a topcoat film made of an ultraviolet curable acrylate resin paint is further formed on a primer film formed on the surf...
