The present invention relates to a transfer film capable of fine transfer of a pattern using partial deposition, and more particularly, to a partial deposition primer composition (A) which can be used in a transfer film having a metal deposition layer to exhibit a partial deposition effect. The invention relates to a primer composition (B) and an adhesive composition (C).

In general, the transfer film is prepared by selectively laminating a release agent layer, a primer layer, a printing layer, an adhesive layer, etc. on the base film, wherein the primer is appropriately controlled adhesion between each layer (layer) when manufacturing the transfer film Or for the purpose of protecting certain layers.

In the transfer film, the metal deposition layer is generally used to give gold or silver to the transfer object. As an example, referring to Japanese Patent Laid-Open No. 04-163198 published in 1992, a transfer film having a metallic luster composed of two metal deposition layers, one pattern layer, and an adhesive layer is proposed.

Although similar in structure, there is also a transfer film in which a metal layer is partially transferred to transfer a discontinuous metal pattern. Japanese Laid-Open Patent Publication No. 08-090999 published in 1996 describes a so-called "partially deposited transfer film". Partial deposition transfer film refers to a transfer film in which a metal deposition layer is formed only on a part of the transfer film, not the entire surface. In Japanese Patent No. 08-090999, after forming a flushing primer layer on a portion that does not require a metal deposition layer, metal deposition is performed. After this, the part is washed and removed.

The method of forming a pattern by removing a part of the metal layer by washing is a very common method used in most partial deposition transfer films, but a method that can exhibit the effect of partial deposition without a cleaning process is known. This method does not form a partial deposition layer by removing a part of the metal deposition layer deposited on the transfer film, but forms a predetermined pattern with an adhesive or a primer, and then transfers an image or an inverted image, such as the formed pattern, onto the transfer object. It is a skill to leave. Thus, the adhesive or primer layer thus formed determines the pattern of the metal layer to be subsequently transferred.

For example, Japanese Patent Laid-Open Nos. 56-000188 and 63-045081 describe a method of forming a pattern with an adhesive on a metal deposition layer, and then forming a partial metal deposition layer having the same shape as the pattern on a transfer object. Doing.

However, this kind of technology is not a method of forming a metal layer or removing only a part of the area on the transfer film, so the term "partial deposition" may not be suitable, but it has an effect similar to that of a real partial deposition transfer film. It is common to use the same terminology.

In addition to the above-described Japanese patents, Korean Patent Laid-Open Nos. 2002-0080690 and 2003-0000241 also describe partial deposition thermal transfer films that do not require a cleaning process. The transfer films described in these two patents have a complicated multilayered structure than those described in Japanese Patent Application Laid-Open Nos. 56-000188 and 63-045081, but the transfer layer partially transfers the metal deposition layer onto the transfer member using an adhesive layer. The same method can be used in that the method is used.

The prior art regarding the adhesive layer for partially transferring the metal layer is briefly introduced in Korean Patent Laid-Open Nos. 2002-0080690 and 2003-0000241. Referring to Korean Laid-Open Patent Publication No. 2002-0080690, an adhesive applied to an aluminum deposition layer and exhibiting a partial deposition effect is an adhesive including a ketone solvent, an acetate solvent, and an aromatic solvent in an acrylic resin, a vinyl resin, and a polyester resin. Korean Patent Laid-Open Publication No. 2003-0000241 also discloses a partial deposition adhesive having such a composition.

Using such a conventional adhesive composition has the advantage of obtaining a transfer film capable of partial transfer without a washing process, but there are disadvantages. Looking at the shortcomings of the adhesive composition for the partial deposition, first, the phenomenon that some of the deposition layer is not deposited due to the lack of adhesion with the metal deposition layer often remains on the base film side, second, using the adhesive composition for partial deposition When another ink layer is laminated thereon after the design is formed, the transferred pattern is easily removed due to poor adhesion with the ink layer.

In the present invention, it was recognized the disadvantages of such a conventional deposition composition for the partial deposition, it was intended to solve this with a partial deposition primer composition (A) described in the present invention. Accordingly, the technical field to which the present invention pertains relates to a primer composition for partial deposition used for the purpose of partially transferring a metal deposition layer.

In addition, the primer composition (B) and the adhesive composition (C) of the present invention are used in close correlation with the primer composition for partial deposition, which are provided together in the present invention.

An object of the present invention is to solve the above problems of the prior art, the metal deposition layer is cleanly deposited using a primer composition (A), a primer composition (B) and an adhesive composition (C) for partial deposition, more clear It is to provide a transfer film capable of transferring fine and detailed patterns.

Hereinafter will be described in detail with respect to the configuration of the present invention.

1 is a diagram showing an example of a transfer film capable of transferring any pattern using the primer composition for partial deposition of the present invention. Referring to Figure 1, the transfer film according to the present invention is a base film (1), a release agent layer (2), the first printing layer (3), deposition protection and coloring layer (4), metal deposition layer (5), primer layer It turns out that it is comprised from (6), the 2nd printing layer 7, the adhesive bond layer 8, and the primer layer 9 for partial vapor deposition.

In FIG. 1, the base film 1 is a glossy or matte polyester-based film having excellent heat resistance, and is generally a PET (polyethylene terephthalate) film, and may be coated with matt to adjust light reflectance of the film.

The release agent layer 2 is for easily depositing the base film 1, and can be sufficiently used as long as it is a release agent containing an acrylic resin.

The first printing layer 3 is a layer provided to express various patterns and colors, and various materials such as dyes, pigments, or metal powder pigments can be used.

The deposition protection and coloring layer 4 is a layer that serves to protect the metal deposition layer 5, and a material having various colors may be used together to exhibit additional coloring effects.

The metal deposition layer 5 is a layer formed by vacuum evaporation of a metal such as aluminum, gold, or silver to give metallic texture and color.

A partial deposition primer layer 9 is provided between the metal deposition layer 5 and the primer layer 6. As shown in FIG. 1, the partial deposition primer layer is applied to the transfer film by a specific pattern such as gravure printing, and serves to leave the metal deposition layer of the reversed pattern on the transfer object after the transfer process.

The primer layer 6 is used for complete adhesion of the metal deposition layer 5, the second printing layer 7 and the adhesive layer 8.

Similar to the first print layer 3, the second print layer 7 is a layer that expresses various patterns and colors by a method such as gravure printing.

The adhesive layer 8 is provided for the purpose of completely bonding all the layers provided thereon to the transfer object.

Hereinafter, a partial deposition primer composition, an adhesive composition, and a method for preparing the primer composition used in the preparation of the transfer film will be described in detail.

Primer composition (A) for partial deposition of the present invention is 20 to 30 parts by weight of methyl methacrylate, 1 to 5 parts by weight of polyether modified dimethylpolysiloxane copolymer, 30 to 40 parts by weight of toluene, 30 to 40 parts by weight of methyl ethyl ketone is dispersed in a high speed mixer for 15 to 20 minutes and then solution polymerized at 100 to 110 ° C. for 9 to 10 hours, and then cooled to 30 to 35 ° C.

Among the compounds, polyether-modified dimethylpolysiloxane is an additive that is applied to a coating object to reduce surface tension, and is typically sold under the trade name BYK-333 by BYK-chemie of USA, and is used in an amount of 1 to 5 parts by weight. When the most desirable partial deposition effect is obtained.

Methyl methacrylate is used to impart a certain degree of adhesion to the primer composition (A) for partial deposition, and it is most preferable to use 20 to 30 parts by weight. It is because it becomes low and when it uses more than 30 weight part, it shows too big a viscosity.

Toluene and methyl ethyl ketone play the role of solvent, which shows the most desirable drying rate when used in total of 60 to 80 parts by weight, and good compatibility with the rest of the materials when both solvents are used in the same ratio.

Referring to FIG. 1, the partial deposition primer composition (A) is printed on a metal deposition layer 5 in a predetermined pattern to form a partial deposition primer layer 9 of FIG. 1. When the transfer film on which the pattern is printed is applied on the transfer member, the metal layer in the region where the partial deposition primer is printed is removed like the transfer film, so that only the metal layer of the reversed image remains on the transfer object.

Primer composition (B) of the present invention is a vinyl chloride-vinyl acetate copolymer, 10 to 20 parts by weight, 5 to 15 parts by weight of methyl methacrylate, 35 to 45 parts by weight of toluene After the dispersion, 30-40 parts by weight of methyl ethyl ketone is dispersed in a high speed mixer for 15-20 minutes and then solution polymerized at 90-100 ° C. for 10-11 hours, followed by cooling to 35-40 ° C.

The vinyl chloride-vinyl acetate copolymer of the primer composition (B) is most typically supplied by Occidental Chemical Co., Ltd. under the trade name Oxy6338. This vinyl chloride-vinyl acetate copolymer is used in the range of 10 to 20 parts by weight, showing the most desirable coating properties.

Methyl methacrylate is used in an amount of 5 to 15 parts by weight, which is smaller than that of the partial deposition primer composition (A), since a sufficient amount of vinyl chloride-vinyl acetate copolymer is used so that sufficient adhesion is ensured. to be.

The primer composition (B) of the present invention is uniformly applied as a primer layer 6 on the metal deposition layer 5, and used for the purpose of more fully bonding the metal deposition layer 5, and oxidation of the metal deposition layer Preventing is another purpose.

After the primer layer 6, a second printing layer 7 is provided, followed by an adhesive layer 8, and the adhesive composition (C) used for the adhesive layer 8 is ABS, PVC, expanded polystyrene, or the like. It has a strong adhesive force to the transfer object of.

Adhesive composition (C) of the present invention is 4 to 10 parts by weight of vinyl chloride-vinyl acetate copolymer, 10 to 20 parts by weight of methyl methacrylate, polyvinyl chloride resin 1-7 parts by weight, 1 part by weight of silica powder, 30-40 parts by weight of toluene, 30-35 parts by weight of methyl ethyl ketone, and 2-8 parts by weight of ethyl acetate, followed by mixing for 25-30 minutes, and mixing the mixture. It is prepared by cooling the polymerization to 75 ~ 80 ℃ for 7 to 8 hours.

Toluene, methyl ethyl ketone, ethyl acetate in the adhesive composition (C) of the present invention is a solvent, and is prepared in the above-mentioned ratio in consideration of the viscosity of the finally prepared adhesive and the solubility of polyvinyl chloride.

In the present invention, the above-described partial deposition primer composition (A), primer composition (B), adhesive composition (C) is used in a modified form as shown in FIGS.

The transfer film shown in FIG. 2 excludes the primer layer 6 and the second print layer 7 from the transfer film of FIG. 1 and directly forms the adhesive layer 8, while simplifying the structure of the transfer film and transferring the transfer film of FIG. There is an advantage that can exhibit the same effect as the film.

The transfer film shown in FIG. 3 is a pattern formed directly on the metal deposition layer 5 by the adhesive composition (C) of the present invention. Using the method of FIG. 3, the pattern formed with the adhesive remains on the transfer object, which is the reverse of the method of FIG. 1 in which the inverted pattern remains. In addition, in FIG. 3, it can be seen that the partial deposition primer layer 9, the primer layer 6, and the second printed layer 7 of FIG. 1 are removed.

4 is a photograph showing an example of transferring a metal deposition layer using the primer composition (A) for partial deposition of the present invention. In the photograph of FIG. 4, the black area is the area where aluminum is transferred and the white area is an empty space. At this time, the actual area of the picture shown in Figure 4 is a very small area of about 0.5 cm x 0.5 cm using the primer composition (A) for partial deposition of the present invention can be seen that a high-resolution clear transfer is possible.
