Abstract
The present invention provides a transparent resin film which enables visual check of the adhesion state after lamination of the transparent resin film on a picture layer provided on a substrate, a decorative board including the transparent resin film, and a method for producing the decorative board. Provided is a transparent resin film for protecting a picture layer provided on one side of a substrate, the transparent resin film including at least: a thermoplastic resin layer; and an external haze layer on a picture layer side.
Claims12
A transparent resin film for protecting a picture layer provided on one side of a substrate,
- the transparent resin film comprising at least:
- a thermoplastic resin layer;
- and an external haze layer on a picture layer side,
- the transparent resin film having a haze value of 90% or lower under the following conditions:
- A polyethylene terephthalate film having a haze value of 0.1% or lower is attached to an opposite side to the thermoplastic resin layer side of the external haze layer with a pure water layer, and the haze value is measured from the thermoplastic resin layer side in a state where a rear surface of the external haze layer is wet,
- the external haze layer having a thickness of 0.5 μm or larger and 20 μm or smaller,
- the transparent resin film having a pattern of protrusions and depressions on an opposite side to the picture layer side, and
- the thermoplastic resin layer having a thickness of 60 μm or larger and 500 μm or smaller.
A transparent resin film for protecting a picture layer provided on one side of a substrate,
- the transparent resin film comprising at least:
- a thermoplastic resin layer;
- and an external haze layer on a picture layer side,
- the transparent resin film having a pattern of protrusions and depressions on an opposite side to the picture layer side, and
- the transparent resin film having a haze value (1) of 70% or higher and a haze value (2) of 70% or lower, where the haze value (1) is a value of haze excluding surface haze on an opposite side to the picture layer side, and the haze value (2) is a value of haze excluding surface haze on the picture layer side and surface haze on the opposite side to the picture layer side.
