Embodiment 1

[0046] A transfer sheet according to the present invention was prepared by dissolving 300 g of a fluoropolyisocyanate resin as a fluororesin in 700 g of toluene to prepare a fluororesin solution, mixing 50 g of glass particles having an average particle diameter of 20 μm with 1 kg of the fluororesin The solutions were mixed and uniformly dispersed therein to prepare a fluororesin coating solution, and then the fluororesin coating solution was coated on one side of a polyethylene terephthalate film having a thickness of 75 μm as a carrier film 1, so that The film was dried to a thickness of 1 μm to form a fluororesin layer 2 , dried at a temperature of 100° C. and coated with an acrylic adhesive in a thickness of 2 μm on top of the fluororesin layer to form an adhesive layer 3 .

Embodiment 2

[0048] In addition to dissolving 500 g of fluoropolyisocyanate resin as a fluororesin in 500 g of toluene to prepare a fluororesin solution, mixing 1 g of pearlescent particles having an average particle diameter of 20 μm with 1 kg of the fluororesin solution and uniformly dispersing therein to prepare a fluororesin coating layer solution, and on one side of a polyethylene terephthalate film with a thickness of 75 μm as the carrier film 1, coat the fluororesin coating solution so that the thickness of the film after drying is 5 μm to form the fluororesin layer 2. , the transfer sheet according to the present invention was prepared by the same conditions and method as in Example 1.

[0049]

Embodiment 3

[0051] The exterior laminate sheet according to the present invention was prepared by thermally transferring the transfer sheet prepared in Example 1 above onto a synthetic resin film of vinyl chloride resin having a thickness of 100 μm as the colored synthetic resin film 4, This transfer sheet is adhered to a synthetic resin film so that the adhesive layer 3 of the transfer sheet is in contact with the synthetic resin film 4, it is heated and laminated, and the carrier film is removed.

Abstract

The present invention relates to a transfer sheet characterized in that a fluororesin layer, wherein reflective particles such as pearl particles or glass particles for giving metal texture are dispersed, is formed on a carrier film and an adhesive layer is formed on said fluororesin layer, and an exterior laminate film characterized in that by transferring said transfer film on a synthetic resin film, the fluororesin layer containing reflective particles forms a surface layer, and an adhesive layer and a synthetic resin film are in turn laminated under said fluororesin layer. The exterior laminate sheet according to the present invention can easily give physical properties, such as excellent weather resistance, corrosion resistance and stain resistance, resulting from the fluororesin to windows/doors and panels, and it is so flexible that it has an effect of easily constructing curved surfaces. In addition, the exterior laminate sheet according to the present invention is allowed to use pearl particles or glass particles having large particle size by adopting formation of a fluororesin layer containing reflective particles as a coating method, whereby it has an effect that a decoration effect may be maximized.

Description

technical field [0001] The present invention relates to a transfer sheet including a fluororesin layer containing light-reflecting particles, an exterior laminate sheet including a fluororesin layer containing light-reflecting particles, and a preparation method thereof. More specifically, the transfer sheet according to the present invention is characterized in that a fluororesin layer in which light-reflecting particles such as pearlescent particles or glass particles are dispersed for imparting a metallic texture is formed on a carrier film, and on the fluororesin layer forming an adhesive layer; and the exterior laminate film according to the present invention is characterized in that by transferring the transfer film onto a synthetic resin film, the fluororesin layer containing light-reflecting particles forms a surface layer, and the adhesive layer and the synthetic resin Films are sequentially laminated under the fluororesin layer. The exterior laminate sheet not only ...
