Embodiment 1

[0077] A polyethylene terephthalate film (manufactured by Toray, trade name T60) having a thickness of 100 μm was used as the first transparent resin layer 102, and a dot pattern was printed on the first transparent resin layer 102 by gravure printing to form print layer 104 .

[0078] In addition, the dot pattern was formed using titanium oxide as an ink, and its total light transmittance was 5%. In addition, the area of ​​the dot pattern pattern with respect to the plane of the first transparent resin layer 102 was 50%, and the non-printed portion N had a portion where a plurality of circles C with a diameter of 1 mm could enter. That is, there are a plurality of spaces of the non-printed portion N corresponding to the size of the circle C having a diameter of 1 mm.

[0079] Next, a polyethylene terephthalate film (manufactured by Toray, trade name T60) having a thickness of 300 μm was used as the second transparent resin layer 106, and an adhesive (Toyobo Byron 63SS 3 μm t...

Embodiment 2

[0097] Example 1 was repeated except that the thickness of the first transparent resin layer 102 was changed to 50 μm and the thickness of the second transparent resin layer 106 was changed to 200 μm.

Embodiment 3

[0099] Example 1 was repeated except that the thickness of the second transparent resin layer 106 was changed to 4000 μm.

Abstract

A decorative film including, from the most surface side, a first transparent resin layer 102, a printed layer 104 having a printed pattern, a second transparent resin layer 106, and a foundation layer 110 in this order, wherein (a) the total light transmittance of the printed pattern of the printed layer is from 0 to 30%; (b) the area of the printed pattern of the printed layer relative to the area of the plane of the first transparent resin layer is 90% or less; (c) the thickness of the second transparent resin layer is form 50 to 5000 µm; and (d) the foundation layer is a brilliant layer or a monochromic layer having an L* value of 60 or higher.

Description

technical field [0001] The present invention relates to a decorative film, in particular to a decorative film having a deep and excellent three-dimensional effect. Background technique [0002] For a long time, decorative films have been widely used on metal or wood materials such as refrigerators, washing machines, air conditioners, automobiles, furniture, cabinets, sliding doors, and cupboards. [0003] In recent years, it has been required to impart design, especially a three-dimensional impression of depth, to the above-mentioned articles. For this reason, centering on home electric appliances, a decorative board in which a printed film is bonded to a glass plate is often used (see, for example, Patent Documents 1 and 2 below). [0004] However, although a glass plate can impart a deep three-dimensional impression, it requires a certain thickness, resulting in an increase in weight, and the problem of degrading handling and operability. In addition, the glass plate is ...
