Description

BACKGROUND OF THE INVENTION The present invention relates to a multilayer decoration, preferably to a glass, ceramic, porcelain substrate, and a process for making it.

The decoration according to the invention is mainly used to decorate glass bottles, plates, mugs, tiles.

For decorative purposes, a variety of surfaces, preferably glass, porcelain and ceramic, are often used for decoration, for which the durability, abrasion resistance, water and chemical resistance of the figure are important, not least the sharp outlines of the figure, vivid colors and many color shades.

Often, drawings are applied to a glass surface where the surface is matted or etched.

Hungarian Patent Application P99 02356 discloses a method of applying an image, such as figures, motifs or text, to the surface of a glass object by applying a computer-generated adhesive transfer foil overlay to the glass surface and subsequently treating the glass surface over the surface. sandblasting while creating a level difference between the figure and the surface and then removing the self-adhesive template.

The above procedure is very labor intensive and less economical.

Also known are methods for applying ceramic or glass surfaces such as bottles, mugs, plates, tiles, vases, etc. the decoration is applied to the surface by fusing stickers.

In this process, the die is pressed onto the surface of the object by means of a clamp or tool and then fired with the object at 500-850 ° C.

After this, the object is cooled down for 6-8 hours.

In this case, the colors of the so-called Pantone® color scheme cannot be used to create the decorations, because due to high temperature burns, color differences are possible and the decor colors are limited.

Fuser stickers are manufactured using a printing or screen printing process, but nowadays they are made using computers.

However, stickers produced by the fusing technique are generally not sufficiently abrasion resistant and not sufficiently abrasion, scratch and chemical resistant.

This latter aspect is particularly important for decorated objects (such as plates, mugs) that are often cleaned, especially in the dishwasher.

They also have the drawback of high energy requirements for production, length of the process and inadequate sharpness of the contours of the figures.

It is an object of the present invention to provide a multilayer decoration (figure, motif, text) embossed with a sticker, preferably glass, ceramic, porcelain, etc. on a surface where the contours of the decoration are sharper and more colorful than those made by known methods.

A further advantage of the decoration according to the invention is that it is possible to use particularly bright colors and that the decoration is less costly and energy consuming and more productive than the known methods, and according to the invention it is possible to produce objects containing multilayer decoration. In addition to the above, the surface of the substrate (e.g., glass bottle, porcelain or ceramic, tile, etc.) may be shaped to any color or matte surface. This is particularly important in the case of glass bottles.

A method of producing a multilayer decoration with a sticker, characterized in that:

a) A digitally generated image and / or text is printed on a water-soluble coating matrix with absorbent base paper 5, and then a transfer lacquer layer is coated with a transfer lacquer layer 8 and a transfer lacquer layer 8 at a temperature of 20-160 ° C. dried,

b) optionally coating the substrate 1 with a base coat of additive fusible plastic varnish 2 and firing the coating at 140-200 ° C,

c) placing a layer 5 of impregnated base paper impregnated with water, covered with a transfer lacquer layer 8, on the surface of the coated substrate 1, dried, and the transfer lacquer layer 8 removed;

d) heat-treated the substrate so decorated at 140-200 ° C,

e) optionally coating the entire surface with a transparent fusible plastic lacquer coating 4; and

f) annealing the lacquer at 140-200 ° C, provided that at least one of steps b) or e) is carried out.

Glass, porcelain or ceramic objects such as plates, mugs or tiles are preferably used as carriers.

The additive fusible plastic lacquer may conveniently comprise an adhesive enhancer, a pigment and / or a filler, but a fusible plastic lacquer may be used which does not contain any pigment and / or filler. When applied, the surface of the substrate may be colored with a varnish, or a coating may be applied to the substrate which produces a matt, sandblasted effect. The fusible plastic lacquer base coat containing additives or the transparent fusible lacquer protective coating can be applied by dipping or spraying (spray gun).

One embodiment of the multilayer decoration applied with a sticker according to the invention is shown in sectional view in Figure 1 and another embodiment in sectional view in Figure 2. Figure 3 is a sectional view illustrating a different embodiment.

Figure 4 is a sectional drawing of a sticker required for the production process of the present invention.

Section 1 shows the substrate 1 to which the fusible plastic lacquer base layer containing the additive 2 is insoluble bonded.

Partly submerged in this layer are decorations applied with a sticker 3 attached to the base coat of the fusible plastic lacquer containing the additive 2, and the

EN 224 925 Β1 Transparent fusible plastic lacquer sealant, integral with the base coat of fused plastic lacquer, containing additives.

This embodiment is used for decorations applied to a substrate 1 in which the decoration applied with the sticker 3 is subject to abrasion or chemical action (for example: washing the object in a dishwasher) and the protective coating of the transparent fusible lacquer 4 prevents the decoration applied to the sticker.

Figure 2 illustrates a variant of the embodiment of the preceding figure, in which the substrate 1 is shown to which the fusible plastic lacquer base layer is insoluble bonded.

Partly submerged in this layer is a decoration embedded with a sticker attached to the base coat of fusible plastic varnish containing additives.

This embodiment is preferably used for decorating wine bottles.

Fig. 3 shows an embodiment in which the surface of the substrate 1 is insoluble bonded to the decoration applied by the sticker 3 and the surface of the substrate 1 and the entire surface of the substrate 1 are insoluble bonded to the protective layer of transparent fusible plastic lacquer 4.

Figure 4 is a sectional view of a sticker consisting of absorbent base paper 5, adhering water-soluble coating 6, printed decoration 7 thereon, and a transfer lacquer layer 8 bonded thereto.

When the sticker is soaked in water, the water-soluble coating 6 dissolves and the printed decoration with the transfer lacquer layer 8 is separated from the absorbent base paper 5. A printed decoration 7 with a transfer lacquer layer 8 is placed on the surface of the substrate 1 and the transfer lacquer layer 8 is removed.

The multilayer decoration applied by the sticker according to the invention and the process for its preparation are illustrated by the following examples.

Example 1

The fusing plastic lacquer (Dunaplast H AQUA, manufactured by Dunaplast Rt., HU) containing a tackifier and a pigment is diluted with water, and the plastic lacquer is applied to a wine bottle (1 carrier) at a spray gun thickness of 20 µm.

The coating is desiccated at 20 ° C for 30 minutes and the coating on support 1 is then annealed in a convection oven at 180 ° C for 45 minutes.

The digitally printed multicolor sticker is coated with a transfer lacquer (Sericol brand name, GB) at 20 µm thickness using a screen cloth.

By soaking in water, the absorbent base paper layer 5 of the sticker is peeled off and the decoration is placed on the surface of the coated substrate. The article was dried at 130 ° C for 20 minutes, and after complete cooling, the transfer lacquer layer was removed. The decorated object is then burned in a convection oven at 180 ° C for 35 minutes, during which time the decoration applied with the sticker 3 sinks into the base layer of the plastic containing the additives 2.

After cooling and storing at room temperature for 30 hours, the decorated wine bottle can be used for filling.

Example 2

In all of the procedures of Example 1, the substrate 1 is not a glass bottle but a ceramic plate.

The operation steps are the same as in Example 1, however, in order to increase the wear resistance of the decoration and to make it more decorative, a spray gun is applied to the surface with 4 transparent fusible plastic lacquers (Dunaplast H AQUA plastic lacquer, manufactured by Dunaplast Co., HU). 20 pm in thickness.

The object was then dried for 2 hours at room temperature and then oven-heated at 180 ° C for 45 minutes.

The object is stored at room temperature and the coating hardens at least 24 hours.

After this time, the decorated object is packed.

Example 3 The substrate used is a tile, which is adhered directly to the surface of the sticker applied as in Example 1 and then dried at 130 ° C for 20 minutes.

The transfer lacquer layer 4 is then removed and the transparent fusible lacquer protective layer 4 is applied by dipping on the decorated object as described in Example 2.

In the following, the procedure of Example 2 is followed.

The multilayer decoration applied by the sticker according to the invention and the process for its production have the following advantages:

The production of the decoration is economical, productive, and the process is suitable for mass production.

The figure and text in the decoration have a sharp outline.

This produces vivid colors with many shades of color.

Decoration applied to various objects, as required by the application, is abrasion and chemical resistant.

In the case of glass bottles, the desired base color can be created, or even matte glass can be created, besides applying the decoration.
