Abstract

PURPOSE:To form a polychromic pattern with three-dimensional feeling, by preparing a layer to be decorated on the surface of a glass product, transferring a transferring material onto it, heat-treating it, so that a thermally movable dye in an ink layer of the transferring material is moved to the layer to be decorated and cooled, removing a resin and the dye left in the layer to be decorated. CONSTITUTION:The transparent or semitransparent layer 2 to be decorated made of ink consisting essentially of a synthetic resin having affinity or adhesiveness to glass is formed on the whole or part of the surface of the glass product 1. The transferring material 3 obtained by laminating successively the release layer 5, the ink layer 6 and the adhesive layer 7 to the substrate sheet 4 is transferred to the layer to be decorated. The resultant material is heated so that a thermally movable dye in the ink layer 6 is moved to the layer 2 to be decorated, and the layer 2 to be decorated is dyed. The transferring material 3 is removed from the layer 2 to be decorated by washing with water, solvent treatment, or buffing, the surface of the decorated layer 2 is simultaneously abraded, and transferring and drawing on the surface of the glass product 1 is finished.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for decorating glass products that can easily form a three-dimensional multicolored pattern on the glass products.

Traditionally, pictures on glass products ("iJ") were printed directly using silk screen printing, and then fired (=J iJ).
The method was to do this. However, the silk screen printing method has the disadvantage that it is difficult to achieve registration and gradation, making it difficult to print beautifully in multiple colors, and that the number of colors increases (therefore, the number of colors increases). Furthermore, since the ink is printed directly on the glass, there is a drawback that the ink in a fluid state flows on the glass surface and is difficult to store. Furthermore, it was not possible to create a three-dimensional effect in the multicolored patterns that were being painted.

In order to eliminate the above-mentioned drawbacks, the present inventors investigated various Ei'I hook methods, and discovered that a transfer material consisting of a release layer iJ3 and an ink layer of a transferred pattern was applied to the substrate sheet 1 as an anode. The dye is transferred to the oxidized aluminum surface, and the dye is transferred to the aluminum surface by utilizing the permeability and adsorption properties of the sublimable dye in the ink layer to the aluminum surface, creating a transferred picture (= J iJ I learned that there is a method to print on glass products.With this method, there is no need for registration when printing on glass products, and beautiful multicolored designs can be printed on glass surfaces without ink flow in the same way as on aluminum. However, this method does not allow the dye to penetrate into the glass.
8″I (A-like multicolored pattern that cannot be covered).

In response to this, the present inventors continued their research and development and discovered that the main component of the surface of the glass product is a synthetic resin that has affinity and adhesion to glass, such as tin boxy, melamine, and Alkyra 1 resin. A transparent or translucent ink or paint is printed or applied, and this is left to stand at room temperature or forcedly dried at a predetermined temperature to form a semi-cured or hardened decorated layer. If a decorative fs layer (transfer picture above) is applied, the sublimable dye in the ink layer of the transfer material will penetrate into the decorated layer, creating a multi-layered color with depth and a three-dimensional effect. It was discovered that color patterns can be obtained.

The present invention has been made based on this knowledge.

The present invention will be explained in detail below with reference to the drawings.

First, as shown in FIG. 1, a predetermined surface or the entire surface of a glass product 1 to be decorated is covered with a >+' hardened layer 2 to be decorated. This decorated layer 2 was formed as follows. However, a rough surface is formed on a part or the entire surface of the glass product 1 by chemical corrosion, such as corrosion by a hydrogen fluoride solution, or physical corrosion, such as corrosion by Lint Plus 1, etc. , compatible thermoplastic and thermoset inks or coatings (
For example, one type or a mixture of 42 or more types of T-boxy, melamine, alkyd acrylic, etc. is printed or coated using methods such as screen printing, gravure printing, and A-printing. Then, store this at room temperature r lj
'i, or force dry at 80°C to 100°C to leave it in a semi-cured state with virtually no tack and partially cured but not completely cured. It was formed by In addition, it is also possible to completely cure the material by forced drying. Whether the decorated layer 2 is provided on a part of the glass product 1 or on the entire surface may be determined as appropriate depending on how the glass product 1 is to be used. At this time, if the entire surface is to be coated, it can be done by applying a coating material that is difficult to print.For example, one glass product can be made into a frosted glass shape, and a part of it can be painted in three-dimensional multicolored colors. When it is desired to form a pattern, a decorated layer 2 marked with -F is formed on the entire surface of the glass product 1 by coating a), and this decorated layer 2 is coated as shown in (e). Transfer painting may be applied to the desired portion of 2.

Transfer material 3 used in the present invention (usually, as shown in FIG. 2, a release layer 5 and an ink layer 6 are sequentially applied to base sheets 1 to 4
3 and an adhesive layer 7, the peel-off layer 5 can be omitted by covering the base sheet 1 with 4 made of resin with high peelability, and the adhesive layer 7 can also be covered. It can be omitted if the ink layer 6 is provided with an adhesive t1 by applying an adhesive or the like. Therefore, the essential constituents of the transfer material 3 used in the present invention are the base sheet 4 and the ink layer 6.
That is.

The above-mentioned base sheets 1 to 4 are supports for forming each layer from layer 5 onwards, and include films such as polyester, polypropylene, polyethylene, and polycarbonate, metal foils such as aluminum, and synthetic materials. It is composed of papers such as paper, polyA reflex coated paper, or composite materials thereof. Note that polyolefin synthetic resin has good surface releasability, so if polyolefin synthetic resin is used for the base sheet 4, the peelable N1 layer 5 described below may be omitted.

The release layer 5 is made of a material with good releasability to the ink layer 6 and the base sheet 4 so that the transfer material 3 is peeled off to the base sheet 1 and the release layer 5 and below are transferred to the liquid added FRB layer 2. It is made of thermoplastic acrylic resin, polyethylene, ethylene-vinyl acetate copolymer resin, polyvinyl alcohol resin, delpene rubber, cyclized rubber, rubber chloride, chlorinated polypropylene, etc., or cellulose acetate. It is composed of cellulose resins such as , 21 to 21-chillulose alone or in combination.

The ink layer 6 is a layer that forms a pattern to be transferred onto the decorated layer 2, and is made of natural and synthetic resins commonly used for ink coating materials, such as edyl cellulose, Miscellaneous resins such as nitrorel [1-s], acrylic resins, styrene resins, chlorinated rubber, cyclized rubber,
Ink in which the vehicle is appropriately selected from vinyl chloride-vinyl acetate copolymer resin, polyamide resin, butyral resin, etc., and heat-transferable dyes such as acid dyes, oil dyes, and sublimation dyes are mixed into this as a colorant. : It is composed of. Note that when this ink layer 6 is mixed with an adhesive or the like to give it adhesion or adhesion, this ink layer 6 can be directly attached to or adhered to the decorated layer 2, which will be explained next. The adhesive layer 7 may be omitted.

The adhesive layer 7 is made of a resin that can be bonded or bonded to the decorated layer 2, such as an acrylic type, a styrene type, a resin type, a rubber type, a polyamide type, and modified products thereof, or It is composed of a thermoplastic resin such as an emulsion type dispersed in.

The transfer material 3 having the above structure can be obtained by sequentially printing and covering the paint constituting each of the layers on the base sheet 4 by a method such as screen printing, gravure printing, offset printing, or the like.

Next, a glass product 1 is manufactured using the transfer material 3 having the above structure.
Transfer the picture to Illi to explain how. First, the adhesive layer 7 side of the transfer material 3 is pressed against the portion (partial or entire surface) of the layer 2 to be decorated using a heating roller for transfer or the like. Then, as shown in FIG. 3, the adhesive layer 7 is adhered to the decorated layer 2, and the transfer material 3 is peeled between the base sheets 1 to 4 and the release layer 5. is transferred to the surface of the decorated layer 2. Next, put this in a heat chamber and heat it for 7
Heating is performed at 0 to 200 DEG C. for 10 to 60 minutes to transfer the heat-transferable dye in the C ink layer 6 into the layer 2 to be decorated, and dye the 11111 layer 3 with this liquid. Due to the heat treatment at this time, the adhesive layer 7 and the ink layer 6 are softened while maintaining their original shapes, and as a result, the contained dye 31 becomes extremely easy to diffuse C, and at the same time, the liquid-added M layer 2 Diffuses from the ink layer 6 through the adhesive layer 7 [Dye can diffuse and permeate deeply into the decorated layer 2 at high temperatures depending on the outline of the dye in the ink layer 6, that is, the pattern. becomes. When this diffusion and permeation have sufficiently progressed, the decorated layer 2 is crosslinked and hardened by the heat treatment. After cooling this, the remaining resin and dye on the layer 2 to be decorated are removed by puff polishing, and at the same time, the surface of the layer 2 to be decorated is polished, resulting in a glass product 1 as shown in FIG. The transfer of the picture onto the surface (= J-ri) is completed. The pattern picture of each color in the decorated layer 2 dyed in this way is continuous from the surface of the decorated layer 2 to the deep part, and it is When viewed from the outside, the pattern appears three-dimensional.Although the pattern appears three-dimensional, the surface of the decorative layer 2 is smooth, making it appear integrated with the glass product, creating a unique A beautiful and eye-catching decorative effect can be obtained.

Note that after heat treatment and cooling, residues such as the adhesive layer 6 may be removed by wiping them off with a cloth soaked in an appropriate organic solvent, such as toluol or pheasant roll, rather than using a puff as described above. Alternatively, the adhesive layer 6 may be made of a water-soluble adhesive such as polyvinyl alcohol in advance and removed and covered by washing with water.

As explained above, the present invention covers a part or the entire surface of a glass product in a transparent or semi-transparent semi-hardened state or hardened state by applying an ink or paint mainly composed of a synthetic resin that has affinity and adhesion to glass. A decorative layer is formed, and a transfer material is transferred onto this decorated layer with an ink layer of a pattern made of a color-sensitive dye, and this is heat-treated to transfer the heat-transferable dye in the ink layer to the above-mentioned. This method transfers and penetrates into the layer to be decorated, is cooled after that, and removes the resin and dye remaining on the layer to be decorated by buffing to a thickness of 1 to 100 mm. There is no need for registration for printing on glass products, no ink runs occur, and multicolor patterns with a three-dimensional effect can be easily and visually formed on glass products.

Next, the present invention will be explained in more detail with reference to Examples.
