Description

Thermal transfer paper of partial solution for solid letter shape}

The present invention relates to a partially dissolved thermal transfer paper having an improved function for three-dimensional patterns by direct transfer with an adherend, and more specifically, to a printed coating film laminated on a base film made of polyester or polypropylene. The present invention relates to a partially melted thermal transfer paper which has a three-dimensional pattern formed on a surface of a wood or a resin molding through dry bonding and secondary melting.

Generally, when manufacturing decorative materials such as frame frames, furniture, interior materials, etc., using wood or synthetic resin molding material, it is necessary to repeat the painting process and drying using paint several times at least once to form three-dimensional patterns on the outer surface. And through the melting process to implement a predetermined three-dimensional pattern. In other words, the three-dimensional pattern was formed by applying the background color on the frame first, applying another color on the frame, and dissolving the applied color partially and then dissolving it again. Since the above method requires a lot of working time due to the complexity and hassle of the processing process, the cost is increased, and the efficiency of the process and production is low, and it also includes a fundamental problem that there are limitations in providing various pattern patterns. Doing.

Therefore, there has been a continuous demand for proposals for patterns diversity and work efficiency.

The purpose of the present invention is to solve the conventional problems of applying paint and removing the dried coating of the paint. The direct thermal transfer method with the adherend dissolves the resin after dry adhesion of the thermal transfer film by heat and pressure only. It is conceived that the three-dimensional pattern can be formed by partially dissolving the printed layer after transfer through the characteristics of the solvent. The formation of the three-dimensional pattern is greatly facilitated, thereby improving work efficiency and speeding up work time, thereby reducing workforce. The manufacturing cost is significantly lower and various patterns of patterns can be created, thereby providing a partly soluble thermal transfer paper for three-dimensional pattern that can be sold at a high price.

The object of the present invention is to coat a release agent layer composed mainly of an acrylic resin to have a peelability on a base film made of polyester or polypropylene, and to apply a printing layer of a water-soluble acrylic resin to impart a partial dissolution function and to deposit metal on it. The layer was formed and the thermosetting protective layer, the secondary acrylic resin printing layer, and the adhesive layer were sequentially laminated and applied on the metal deposition layer. The purpose of this is achieved by dry bonding the thermal transfer film with pressure alone and enabling the formation of a three-dimensional pattern through the secondary dissolution process, which simplifies the process, enables fast working time, and creates various pattern patterns.

With reference to the accompanying drawings, the three-dimensional pattern-dissolving transfer paper according to the present invention will be clearly understood its features and advantages by the embodiments described in detail below.

As shown in FIG. 1, the three-dimensional pattern-dissolved transcription paper according to the embodiment of the present invention expresses a total of seven layered structures.

First, a base film (1) of a polyester or polypropylene film having excellent glossiness or matte thermal stability, and a release agent layer synthesized from ketone, ethyl acetate, and toluene as main components of acrylic (MMA) resin are applied to the base film. Step being made,

After the coating step of the release agent layer is applied to the water-soluble acrylic resin pigment and the primary printing layer made of methanol, ethanol, isopropyl alcohol, water, and

Coating the metal powder on the primary print layer or applying a metal layer to vacuum-deposit the metal thin film after the coating step of the primary print layer;

Applying a protective layer comprising a ketone, acetate, toluene, alcohol solvent and a thermosetting curing agent to the acrylic resin to prevent dissolution of the lower printed layer after coating the metal layer;

Applying a second printing layer after application of the protective layer;

Through the step of applying the adhesive layer for adhesion with the adherend, a three-dimensional pattern-dissolving transfer paper (A) having a total of seven layered structures is manufactured.

The release agent layer 2 applied on the base film 1 of the partially dissolved transfer paper (A) is uniformly dissolved in a ketone, toluene, and ethyl acetate solvent on the surface of the base film (1). The release agent layer 2 achieves peelability between the primary printing layer 3 and the base film 1. The resin weight of the release agent layer is 15 to 20wt% is correct.

Subsequently, the first printing layer 3 is coated with a thin film of a liquid prepared by dissolving a water-soluble acrylic resin in a solvent such as methanol, ethanol, water, and dispersing a weather-resistant pigment freely selected. (3) Applying bronze or aluminum powder and paste to give the appearance efficiency, or forming a metal layer 4 using a metal deposition film, acrylic to prevent the dissolution of each of the lower printed surface The protective layer 5 formed of a mixture of a ketone-based, acetate-based, alcohol-based solvent and a thermosetting curing agent is applied to the urethane as a main component. The resin weight of the primary printed layer is preferably 25 to 30wt%.

Thereafter, the secondary printed layer 6 of a thin film is laminated on the protective layer 5, and the secondary printed layer 6 also has a small amount of additives, pigments, ketones, and toluene in acrylic (MMA) resin and vinyl resin. Prepared using isopropyl alcohol, ethyl acetate solvent, and finally by applying an adhesive layer (7) mainly based on acrylic (MMA) system, simply thermal transfer to wood or synthetic resin molding material (not shown) and then separated By processing, the desired three-dimensional pattern can be implemented.

At this time, the adhesion may be preferably to crush the transfer paper at a pressure of about 130 degrees and a speed of about 36 m / min, the pressure roller, but is not limited to this, the adhesive layer 7 through the Mayba or copper plate By uniformly coating the already laminated coating film, it is provided with a transfer paper having excellent three-dimensional pattern formation.

Hereinafter, the present invention will be described in more detail with reference to Examples.

<Example 1>

A release agent layer (15 wt% resin), a water-soluble primary printing layer (25% resin weight), a metal printing or metal vacuum deposition layer, a thermosetting protective layer, and a secondary layer on a polyester or polypropylene film having a thickness of 12 to 25 microns. The printing layer and the adhesive layer are sequentially laminated to prepare a partially dissolving transcript for three-dimensional patterns. The partially transferred thermal transfer paper to be transferred is squeezed at a speed of about 5 m / min and a temperature condition of about 130 degrees. In the following process, the aqueous printing layer 2 is first partially dissolved with the designated solvent, the metal printing or metal vacuum deposition layer 4 is secondly dissolved with the designated solvent, and the desired product is produced after drying.

Comparative Example 1

After spraying the coating material with a predetermined color, it is completely dried. After the second spraying operation with gold and silver powder in the next process, it is completely dried. Then, the water-soluble paint is completely sprayed and dried in the next process. After washing, the aqueous paint is partially dissolved and dried first, and then the gold and silver layers are secondly washed to dissolve the desired product.

Therefore, the present invention, in the production of decorative frames such as frame frames, furniture, architectural interior materials, such as wood or synthetic resin molding material, by heat-bonding the thermal transfer film only by heat and pressure by dissolving the printed layer by part by secondary melting process It is possible to form various three-dimensional patterns as well as simplify the work process and at the same time have excellent surface patterns and economics.
