cremation material

The present invention relates to a cosmetic material.

In building materials, furniture, home appliances, etc., when a member to be used is to be decorated (加飾), a cosmetic material is generally used.

In particular, when a cosmetic material is used as a flooring material, slip resistance is required from the viewpoint of safety.

For example, Patent Document 1 discloses a laminate for the surface of a flooring material in which a surface protective layer has a laminated structure of two or more layers, and a resin-based bead is added only to the outermost layer to reduce friction and impart anti-slip properties. has been

On the other hand, in everyday life, in an environment in which water typified by a kitchen, a changing room, etc. may be used, ie, in an environment around water, a person may fall down when a floor gets wet with water.

By the way, in the laminated body for flooring surfaces mentioned above, although it was considered to improve the slip resistance at the time of drying, it did not consider about the slip resistance at the time of getting wet with water, and there existed room for improvement.

Conventionally, as a flooring material used in bathrooms, etc., which is always wet with water, a flooring material having a deep recessed portion and a wide recessed portion provided with a surface shape to improve anti-slip properties when wet with water is sold.

However, the surface shape is a geometric thing such as a checkerboard shape with regularity, and there is a problem that the design of the underlying material is limited, and there is little demand for applications requiring high designability such as a wood grain pattern or a protrusion pattern.
