example 1

[0107] Example 1: Manufacture of red multilayer sheet

[0108] Use 250g / m2 Main paper sold by Ayo Wiggins Premium Paper Co. Paper as the lower support layer, an aluminum deposition with a thickness of 20 nm as a metal layer, a red varnish with a thickness of 3 μm, a PET film with a thickness of 12 μm as a plastic layer, and a matt varnish layer with the following composition were produced Figure 7 A printable multilayer sheet of the type shown in (without primer sublayer 733). The matt varnish layer has the following composition:

[0109] - By weight, polyurethane particles account for 33%, and its average diameter is about 4μm (trade name sold by Dainishiseika Corporation),

[0110] - By weight, precipitated silica particles (used as a smoothing agent) account for 0.3%, and their average diameter is about 5 μm (trade name Sold by Grace Division),

[0111] - By weight, based on the trade name Rolflex sold by Lamberti The mixture of polyurethane and acrylic adhesive ...

example 2

[0114] Example 2: Manufacture of a multilayer sheet of the type of Example 1 with an additional primer sublayer

[0115] Using the same product used in Example 1, except the product used for the support layer is different, prepare Figure 7 Another multi-layer printable sheet of the type (with primer sublayer 733). In this example, the support layer uses 300g / m2 Main The primer sublayer is provided by Luminescence INC., No. 10843X or 11035G. It was provided in an amount of about 1 g / m2 on the upper surface of the PET film, which had been preliminarily treated with acrylic in this example.

example 3

[0116] Example 3: Manufacture of a multilayer sheet of the type of Example 1 additionally with a crosslinker in the matt varnish wear layer

[0117] The matt varnish wear layer included, in addition to the products listed in Example 1, an aziridine-based crosslinker sold under the trade name CX1000 by the company DSM Neoresin.

Abstract

The invention relates to a multilayer printable sheet (10), including a bottom support layer (12), an intermediate metal layer (14) and a top layer (16) made of transparent or translucent plastic material, a top surface of said layer of plastic material being covered with a coating layer (18) made of a transparent or translucent matte varnish with a soft or silky touch.

Description

technical field [0001] The invention relates to a multi-layer board and its manufacturing method, wherein said board comprises a lower support layer, a middle metal layer and an upper layer made of transparent or translucent plastic material. Background technique [0002] The superimposition of layers of plastic material and metal gives the optical properties of the sheet to produce a visual depth effect, which is aesthetically very beneficial. Also, when the layer of plastic material is coloured, the sheet can have a color-changing appearance, characterized by changes in reflection, color or nuance of the sheet as the viewing angle changes. [0003] Such sheets can be used in different fields, such as in the field of packaging, for example for packaging food or cosmetics, or in the field of graphic arts, such as printing supports for advertising and the like. In the packaging sector, the sheet may be subjected to multiple cutting and folding operations, so it must have sui...
