Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a radiation-curable resin composition for a transfer sheet, and a method for producing a transfer sheet and a decorative sheet using the same.

[0002]

2. Description of the Related Art In recent years, as interior and exterior wall materials of buildings such as houses and buildings, many using decorative panels such as tiles and panels have been used.

[0003] In general, a clear layer made of a thermosetting resin is often formed on the surface of such a decorative board in order to impart gloss, durability, and scratch resistance. Such a clear layer can be formed by applying a paint containing a thermosetting resin, but recently, a UV curable resin is used instead of the thermosetting resin on a peelable base film. A method for forming a clear layer by applying a coating containing a transfer layer to form a transfer layer, bonding the transfer sheet to a substrate, and then irradiating with ultraviolet light to cure the transfer layer and peeling and removing the base film. Has been developed and put into practical use. With this method,
High heat resistance is not required for the base film, and an inexpensive polyethylene terephthalate (PET) film can be used.

In many cases, the transfer sheet to be bonded to the base material is actually 300 to 1000 m long in view of workability and production efficiency. Therefore, from the viewpoint of ease of transportation and reduction of the occupied space, the transfer sheet is stored and transported as a product in a rolled state around a core of a paper tube or the like, and then the cosmetic sheet is transferred. In most cases, when it is attached to a board, it is pulled out from the rolled material and used.

However, in the production process of the transfer sheet, the environmental temperature is generally not controlled in many cases, and the environmental temperature is -10 ° C. depending on the season and time zone.
To around 60 ° C. In particular, when the temperature is high, such as in the daytime in summer, there is a problem that the resin layer of the radiation-curable resin contained in the transfer sheet is softened and a winding deviation occurs when the transfer sheet is wound into a roll. Also, in the same manner as in the manufacturing process, the place where the transfer sheet wound in a roll is stored is often not controlled in the environmental temperature.
There has been a problem that wrinkles are generated when the transfer sheet is bonded to the base material due to the occurrence of creasing or blemishes on the surface of the transfer sheet or the deformation of the roll cross-sectional shape.

[0006]

Therefore, according to the present invention, the transfer sheet can be easily attached to a decorative board without causing the above-mentioned problem due to a change in environmental temperature when the transfer sheet is wound and stored.

(2) irradiating the base film, and after the step (2), a step (3) of peeling the base film, wherein the transfer sheet is the transfer sheet described above. It is characterized by the following.

In the transfer sheet, when a protective film layer is provided on the transfer layer, or when the pattern layer is formed of a transfer foil layer and a mount layer is provided thereon, After the protective film layer and the backing layer are peeled off to expose the transfer layer or the design layer, the above step (1) can be performed.

In the step (1), specifically, an adhesive is applied to the surface of any one of the transfer layer, the design layer and the base coat layer, and the solvent component remaining in the adhesive is This is a step of drying after drying so as to remove it, bonding to a base material, and heating and curing at a predetermined temperature. here,
The above-mentioned drying is not performed for curing but is performed from the viewpoint of adhesion, and the drying temperature and the drying time are appropriately determined depending on the type of the adhesive and the thickness of the adhesive layer. The predetermined temperature is determined depending on the type of the adhesive, but is preferably from 60 to 150 ° C. from the viewpoint of energy saving and resource saving and the heat resistance of the transfer layer and the design layer.

As a method of applying the adhesive, for example,
Brush coating, dip coating, spray coating,
Examples of the method include roll coating and curtain flow coating. From the viewpoints of economy and stability of mass production of the adhesive layer obtained, roll coating is preferred. Further, the coating thickness of the adhesive is not particularly limited, but is generally 5 to 5 as a dry film thickness.
It is set to 100 μm. If the dry film thickness is less than 5 μm, the effect as an adhesive cannot be sufficiently obtained.
On the other hand, if the dry film thickness is more than 100 μm, an effect proportional to the dry film thickness cannot be obtained, so that it is not economical and it may take time to dry the formed adhesive layer.

The adhesive is not particularly limited, but preferably contains the thermosetting resin component described in the above base coat composition from the viewpoint of adhesiveness.

The type of the adhesive can be selected according to the required performance as a decorative board. For example, when a decorative board is used for a bathroom wall material, a water-resistant adhesive is preferable, and when it is used for a kitchen wall material, a heat-resistant adhesive is preferable.

As described above, the above adhesive has not only the performance as a normal adhesive but also the effect of hiding the base such as unevenness and color of the base when the obtained transfer sheet is pasted on the base. A design property can also be imparted by having them together or by further including a pigment.

In the method for producing a decorative board according to the present invention, after the above-mentioned step (1), the above-mentioned steps (2) and (3) are further carried out. The same thing as the case where it does not exist can be mentioned.

The decorative board of the present invention can be obtained by the above step (1),
It can be obtained by (2) and (3).
