Description

High-gloss pattern film for vehicle, and manufacturing method thereof

The present invention relates to a high-gloss pattern film for a vehicle, and a method for manufacturing the same, and more particularly, to a high-gloss pattern film for a vehicle that has excellent gloss, implements various patterns and colors, and has excellent durability, and a method for manufacturing the same.

Paint Protection Film (PPF) is being constructed for the purpose of protecting the painted surface of a vehicle from scratches or contamination by stone chips and tree branches. Recently, a color film (Color PPF) in which design elements such as color and pattern are added to the existing PPF, and a pattern film (Pattern PPF) are being developed.

In general, PPF is made of PVC material, so it is inexpensive, and various colors and patterns can be realized through surface printing and special treatment, so that the gloss can be effectively maintained. However, PVC material has relatively weak elasticity and physical properties such as tensile strength, so there is a problem that it can be easily damaged even by a small impact.

On the other hand, the pattern film is a PPF in which a pattern including irregularities is added, and Korean Patent No. 10-1173918 (three-dimensional pattern film, protection cover and manufacturing method thereof) is a three-dimensional pattern in which a pattern is formed on an adhesive layer or a hard coating layer. Disclosed is a technology for a film. When such a film is applied to the painted surface of a vehicle, a pattern may be given to the painted surface, or the color may be changed at the same time as the pattern is given depending on the product.

However, these patterned films are not suitable for protecting the painted surface of a vehicle because they are vulnerable to shocks or scratches from the external environment due to irregularities. In addition, when a film layer having a self-healing function is formed on the pattern for scratch restoration, there is a problem in that the inner space of the unevenness is filled and the three-dimensional effect of the pattern is rapidly reduced.

Structure of high-gloss pattern film (1) for vehicles

1 schematically shows a laminated structure of a high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention.

As a high-gloss pattern film for a vehicle according to an embodiment of the present invention (1), the self-healing layer 110 comprising a polyurethane methacrylate, and an isocyanate curing agent; a first base layer 120 disposed under the self-healing layer 110 and comprising a thermoplastic polyurethane film; a pattern layer 200 disposed below the first base layer 120 and having a pattern including concavities and convexities formed thereon; a second base layer 310 disposed under the pattern layer 200 and comprising a thermoplastic polyurethane film; and a third base layer 320 disposed under the second base layer 310 and including an adhesive layer 321 , wherein a portion of the upper surface of the pattern layer 200 is the first base layer By laminating on 120 , an empty space may be formed between the pattern layer 200 and the first base layer 120 due to the unevenness.

The third base layer 320 according to an embodiment of the present invention may further include a color layer 322 disposed above the adhesive layer 321 .

1, the high-gloss pattern film for a vehicle according to an embodiment of the present invention (1) according to an embodiment of the present invention is a self-healing layer 110, the self-healing layer 110, a first base layer disposed under the 110, 120, The pattern layer 200 disposed under the first base layer 120 , the second base layer 310 disposed under the pattern layer 200 , and the second base layer 310 disposed under the second base layer 310 . A third base layer 320 may be included. In addition, the third base layer 320 may include a color layer 322 disposed under the second base layer 310 , and an adhesive layer 321 disposed under the color layer 322 . .

That is, the vehicle high-gloss pattern film (1) is the self-healing layer 110, the first base layer 120, the pattern layer 200, the second base layer 310, and the third base layer ( 320) may be included.

In an embodiment of the present invention, the self-healing layer 110 may include polyurethane methacrylate, and an isocyanate curing agent.

The self-healing layer 110 of the existing vehicle protective films has low performance for scratch restoration and water repellency. Due to this, there is a problem in that the contamination resistance property is not good, and thus it is vulnerable to external contamination.

In order to solve this problem, the self-healing layer 110 including the above components is formed on the surface of the high-gloss pattern film 1 for vehicles of the present invention. In this case, the self-healing layer 110 has excellent properties for scratch restoration, water repellency, and stain resistance, so that it is possible to effectively protect the painted surface of the vehicle from scratches or contamination.

Preferably, the self-healing layer 110 according to an embodiment of the present invention may include 75 to 90 parts by weight of polyurethane methacrylate, and 15 to 40 parts by weight of an isocyanate curing agent.

The composition range of the self-healing layer 110 as described above corresponds to a range capable of implementing self-healing properties of self-recovering scratches.

That is, as the self-healing layer 110 is made of the above composition, the high-gloss pattern film 1 for a vehicle can implement a self-healing ability suitable for self-repairing scratches generated on the surface. Due to this, when a scratch is generated on the surface of the high-gloss pattern film 1 for a vehicle, the scratch is restored by itself by the self-healing layer 110 , thereby improving scratch resistance.

In addition, the composition range of the self-healing layer 110 as described above corresponds to a range capable of implementing excellent water repellency.

That is, as the self-healing layer 110 is made of the above composition, the high-gloss pattern film 1 for a vehicle has excellent water repellency that does not easily permeate the surface of contaminants such as rainwater, mud, and insects. Accordingly, when contaminants are deposited on the surface of the high-gloss pattern film 1 for vehicles, the contaminants do not permeate by the self-healing layer 110 , so that the contamination resistance characteristics can be improved.

That is, by forming the self-healing layer 110, it is possible to implement the high-gloss pattern film 1 for a vehicle excellent in scratch resistance, water repellency, and stain resistance.

Preferably, the high-gloss pattern film for a vehicle (1) forms the self-healing layer 110 made of a material having high elasticity, thereby improving the scratch resistance, water repellency, and stain resistance of the high-gloss pattern film for a vehicle (1). It can be improved, and the effect of effectively protecting the painted surface can be exhibited.

In an embodiment of the present invention, the first base layer 120 may be disposed below the self-healing layer 110 .

The existing pattern film for vehicles is manufactured by coating the self-recovery layer 110 immediately after forming a pattern including irregularities on the upper surface of the pattern layer 200 . At this time, since the self-healing layer 110 may be coated to the inside of the unevenness, there is a problem in that the gloss deterioration of the pattern film may occur.

In order to solve this, in the present invention, the first base layer 120 is disposed below the self-healing layer 110 . In this case, since the self-healing layer 110 is not coated with the pattern layer 200 by the first base layer 120 , it is possible to prevent deterioration of the gloss of the film.

In more detail, the first base layer 120 is disposed between the self-healing layer 110 and the pattern layer 200 so that the self-healing layer 110 is formed on the pattern layer 200 . Filling can be prevented. In this case, the blank space by the pattern can be maintained, thereby preventing the deterioration of the gloss of the film.

That is, as the first base layer 120 is laminated on the upper surface of the pattern formed on the pattern layer 200 , the gloss of the high-gloss pattern film 1 for a vehicle can be effectively improved.

Preferably, by arranging the first base layer 120 between the self-healing layer 110 and the pattern layer 200 and laminating it on the upper surface of the pattern formed on the pattern layer 200, excellent gloss is obtained. It is possible to exhibit the effect of providing the vehicle high-gloss pattern film (1) having.

In addition, in an embodiment of the present invention, the first base layer 120 may include a thermoplastic polyurethane film, and preferably, 95 to 100 parts by weight of the thermoplastic polyurethane film.

Existing pattern films for vehicles are made of PVC material, so various colors and patterns can be implemented relatively simply. However, due to the nature of the material, there is a problem that it can be easily damaged even if it receives a small impact from the external environment.

In order to solve this problem, the high-gloss pattern film 1 for a vehicle of the present invention is formed with the first base layer 120 including the above material.

Thermoplastic polyurethane takes a very long time to break, and has relatively high elasticity, so it is a material with excellent durability and impact resistance. The first base layer 120 including the thermoplastic polyurethane may have excellent durability and impact resistance.

That is, the high-gloss pattern film 1 for a vehicle having excellent durability and impact resistance can be implemented by the first base layer 120 made of a thermoplastic polyurethane film.

In addition, the thickness of the first base layer 120 according to an embodiment of the present invention is 25 to 200 micrometers. Preferably, the thickness of the first base layer 120 is 100 micrometers or more.

The thickness range of the first base layer 120 as described above corresponds to a range in which excellent durability and impact resistance can be realized, and excellent gloss can be realized.

Preferably, since the first base layer 120 is formed to have the same thickness as above, it is possible to effectively absorb an impact from the outside, and to prevent the void space formed in the pattern layer 200 from being pressed by the unevenness. Therefore, it is possible to implement a high-gloss pattern film (1) for vehicles having excellent gloss.

That is, as the first base layer 120 is made of the above components and thickness, it is possible to implement the high-gloss pattern film 1 for vehicles having excellent durability and impact resistance, and excellent gloss.

In an embodiment of the present invention, the pattern layer 200 is disposed below the first base layer 120 , and a pattern including concavities and convexities may be formed on the upper surface.

As described above, the first base layer 120 is disposed between the self-healing layer 110 and the pattern layer 200 so that the self-healing layer 110 is formed on the pattern layer 200 . Filling can be prevented.

That is, an empty space may be formed by maintaining a pattern including concavities and convexities on the upper surface of the pattern layer 200 according to an embodiment of the present invention.

At this time, when light is incident on the pattern layer 200, the diffuse reflection phenomenon can be suppressed by the unevenness, and the pattern three-dimensional effect of the high-gloss pattern film 1 for a vehicle can be improved.

Also, the pattern according to an embodiment of the present invention may be formed by rolling the upper surface of the pattern layer 200 applied to a predetermined thickness with a roll having a predetermined pattern engraved thereon.

That is, the pattern is formed by a coating method rather than a surface printing method, and thus has a relatively three-dimensional characteristic. At this time, although the gloss of the film may be reduced due to refraction of light in the pattern, excellent gloss may be realized due to the laminated structure with the first base layer 120 .

In addition, in an embodiment of the present invention, the pattern layer 200 may include 75 to 90 parts by weight of polyurethane methacrylate, and 15 to 40 parts by weight of an isocyanate curing agent.

The composition range of the pattern layer 200 as described above corresponds to a range that can implement a layer capable of forming a three-dimensional pattern through rolling by a roll. That is, as the pattern layer 200 is made of the above components, it is possible to form a pattern including concavities and convexities on the upper surface by a surface coating method.

However, the components and compositions of the pattern layer 200 are not limited thereto, and may be variably selected according to the working environment such as the complexity and size of the pattern.

In an embodiment of the present invention, the second base layer 310 is disposed below the pattern layer 200, and includes a thermoplastic polyurethane film, and preferably includes 95 to 100 parts by weight of a thermoplastic polyurethane film. can

As described above, the thermoplastic polyurethane corresponds to a material having excellent durability and impact resistance due to its high elasticity. That is, it is possible to exhibit the effect of improving the durability and impact resistance of the high-gloss pattern film 1 for a vehicle by the second base layer 310 made of a thermoplastic polyurethane film.

In addition, the thickness of the second base layer 310 according to an embodiment of the present invention may be 12 to 50 micrometers.

In general, a film attached to a vehicle paint surface has a problem in that construction becomes difficult as the total thickness of the product increases.

In consideration of this, in the present invention, the second base layer 310 was formed to have the thickness range as described above. That is, as the second base layer 310 was formed to be relatively thinner than the first base layer 120 , the workability of the high-gloss pattern film 1 for a vehicle was improved.

In an embodiment of the present invention, the third base layer 320 may be disposed below the second base layer 310 and include an adhesive layer 321 .

In addition, as described above, in an embodiment of the present invention, the third base layer 320 may further include a color layer 322 disposed above the adhesive layer 321 .

As shown in FIG. 1 , the third base layer 320 according to an embodiment of the present invention includes a color layer 322 disposed under the second base layer 310 , and the color layer 322 . ) may include an adhesive layer 321 disposed on the lower side.

The color layer 322 may include, in an embodiment of the present invention, 50 to 60 parts by weight of a urethane acrylate binder, 5 to 10 parts by weight of a color pigment, 1 to 5 parts by weight of a curing agent, and 30 to 60 parts by weight of a solvent. can

Existing vehicle pattern films implement color by surface printing or by adding pigments to thermoplastic polyurethane or the adhesive layer 321 .

However, since the film is made of PVC material, it is not suitable for protecting the painted surface of the vehicle. When a pigment is added directly to the thermoplastic polyurethane, yellowing is noticeable. There is a risk of this eluting, and there is a problem in that the physical properties are lowered.

In order to solve this problem, in the high-gloss pattern film 1 for a vehicle of the present invention, a separate color layer 322 is disposed under the second base layer 310 . In this case, since the color layer 322 includes a component having the above composition range, various colors can be stably implemented.

That is, the high-gloss pattern film 1 for a vehicle can exhibit the effect of stably implementing various colors by separately disposing the color layer 322 including a color pigment.

In addition, the composition range of the color layer 322 as described above corresponds to a range capable of implementing various colors and improving adhesion. In this case, the color layer 322 corresponds to a primer layer.

More specifically, in an embodiment of the present invention, when the adhesive layer 321 includes an acrylic component, it may not adhere well to the second base layer 310 including the thermoplastic polyurethane. At this time, by disposing the color layer 322 including a urethane acrylate binder between the second base layer 310 and the adhesive layer 321, the second base layer 310 and the adhesive layer ( 321) can strengthen the adhesion between them.

That is, since the color layer 322 is made of a component series similar to that of the second base layer 310 and the adhesive layer 321 , it serves as a primer to prevent the transfer of the adhesive layer 321 . can be effective.

However, the components and composition ranges of the color layer 322 are not limited thereto, and may be variably selected according to a required color or texture. For example, in another embodiment of the present invention, the color layer 322 may include an acrylic binder including an acrylic copolymer.

Meanwhile, the adhesive layer 321 may include 70 to 80 parts by weight of an acrylic copolymer, 0.5 to 5 parts by weight of a curing agent, and 30 to 60 parts by weight of a solvent in an embodiment of the present invention.

When constructing a pattern film for an existing vehicle, an acrylic pressure-sensitive adhesive with high adhesive strength is mainly used to prevent the film from lifting.

However, since the acrylic pressure-sensitive adhesive has poor adhesion to the thermoplastic polyurethane, there is a problem in that the pressure-sensitive adhesive is transferred to the vehicle paint surface when the film is removed.

To solve this, in the present invention, an adhesive layer 321 including a component having the above composition range was formed. The composition range of the adhesive layer 321 as described above corresponds to a range showing strong adhesiveness. Accordingly, it is possible to prevent the floating phenomenon of the high-gloss pattern film (1) for a vehicle.

In addition, in one embodiment of the present invention, between the second base layer 310 and the adhesive layer 321 in order to improve the adhesion between the second base layer 310 and the adhesive layer 321. The color layer 322 may be disposed. Accordingly, it is possible to prevent the transfer phenomenon when removing the high-gloss pattern film (1) for the vehicle.

However, the components and compositions of the adhesive layer 321 are not limited thereto, and may be variably selected according to the construction target and environment.

Meanwhile, as shown in FIG. 1 , the high-gloss pattern film 1 for a vehicle may include a protective film layer 400 disposed above the self-healing layer 110 . Accordingly, the surface of the high-gloss pattern film 1 for a vehicle may be protected by the protective film layer 400 .

Meanwhile, as shown in FIG. 1 , the high-gloss pattern film 1 for a vehicle may include a release film layer 500 disposed under the adhesive layer 321 .

The release film preferably has a weak peeling force because it should be easily removed by the installer during the construction of the high-gloss pattern film (1) for the vehicle. In this case, the release film may include any general release film in which the peeling force is difficult to become strong even if time elapses while being attached to the adhesive layer 321 .

As shown in Figure 1, the high-gloss pattern film for a vehicle (1) is the self-healing layer 110, the first base layer 120, the pattern layer 200, the second base layer 310, The third base layer 320 including the color layer 322 and the adhesive layer 321 may have a laminated layered structure.

The thickness of the self-healing layer 110 according to an embodiment of the present invention is 5 to 30 micrometers, the thickness of the first base layer 120 is 25 to 200 micrometers, and the thickness of the pattern layer 200 is The thickness may be 5 to 50 micrometers, the thickness of the second base layer 310 may be 12 to 50 micrometers, and the thickness of the adhesive layer 321 may be 5 to 50 micrometers. In addition, the thickness of the color layer 322 may be 5 to 50 micrometers.

As each layer constituting the high-gloss pattern film (1) for a vehicle of the present invention is formed in the same thickness range as described above, a high-gloss pattern film (1) for a vehicle that has excellent gloss and various patterns and colors and has excellent durability is provided. can do.

At this time, the pattern layer 200 is formed between the upper film layer 100 and the lower film layer 300 , and the upper surface of the pattern formed on the pattern layer 200 is on the upper film layer 100 . By being attached, the upper film layer 100 , the pattern layer 200 , and the lower film layer 300 may form an integrated structure. That is, it is possible to provide a high-gloss pattern film 1 for a vehicle having an excellent gloss by the structure as described above.

On the other hand, as a method of manufacturing a high-gloss pattern film for a vehicle (1) according to an embodiment of the present invention, the high-gloss pattern film for a vehicle (1) includes a polyurethane methacrylate, and a self-healing layer comprising an isocyanate curing agent (110); a first base layer 120 disposed under the self-healing layer 110 and comprising a thermoplastic polyurethane film; a pattern layer 200 disposed below the first base layer 120 and having a pattern including concavities and convexities formed thereon; a second base layer 310 disposed under the pattern layer 200 and comprising a thermoplastic polyurethane film; and a third base layer 320 disposed under the second base layer 310 and including an adhesive layer 321 , wherein a portion of the upper surface of the pattern layer 200 is the first base layer By laminating on 120 , an empty space may be formed between the pattern layer 200 and the first base layer 120 due to the unevenness.

Comparative Example 1

PVC Color Wrapping Film (Product Name: Carbon Real) sold by CYS. That is, Comparative Example 1 corresponds to a vehicle pattern film made of PVC material.

Comparative Example 2

Color TPU PPF (product name: G-suit) sold by Ad-Winner. That is, Comparative Example 2 corresponds to a PPF in which a color is directly implemented on a thermoplastic polyurethane.

Comparative Example 3

Color PSA PPF. That is, Comparative Example 3 corresponds to a PPF in which a color is realized by adding a pigment to the adhesive layer 321 .

3 schematically shows the appearance of a high-gloss pattern film 1 for a vehicle and a comparative example according to embodiments of the present invention.

Figure 3 (a) shows the appearance that can confirm the pattern shape of Example 1, Figure 3 (b) shows the appearance that can confirm the pattern shape of Example 2, Figure 3 (c) is the appearance of Comparative Example 1 It shows the appearance that can confirm the pattern shape.

As shown in FIGS. 3(a) to 3(c), it can be confirmed that Examples 1, 2, and Comparative Example 2 are all products to which a carbon pattern is applied.

Figure 4 schematically shows the tester used for the gloss test.

In this experiment, gloss test was performed using LINSHANG's LS-192 equipment. In this test, the glossiness can be measured by irradiating the product with light at a certain angle, and the higher the measured value, the brighter it is seen with the naked eye.

Table 1 shows the results of testing the glossiness of Examples 1, 2, and Comparative Example 2.

film glossiness Example 1 123.1 Example 2 39.5 Comparative Example 1 97.2

As shown in Table 1, it was found that the glossiness of Example 1 was 123.1, the glossiness of Example 2 was 39.5, and the glossiness of Comparative Example 1 was 97.2.

Example 1 corresponds to a film in which a separate base layer exists between the self-healing layer 110 and the pattern layer 200 . In this case, an empty space can be maintained between the patterns of the pattern layer 200 , thereby suppressing diffuse reflection of light irradiated to the film, thereby realizing excellent gloss.

On the other hand, Example 2 corresponds to a film in which a separate base layer does not exist between the self-healing layer 110 and the pattern layer 200 . In this case, the self-healing layer 110 may be filled between the patterns of the pattern layer 200 , and the light irradiated on the film may be refracted by the pattern, so that the gloss may be rapidly reduced.

In addition, Comparative Example 1 corresponds to a film in which a pattern and a color are formed through surface printing. Comparatively superior glossiness can be realized compared to Example 2, but it can be seen that the glossiness is relatively reduced compared to Example 1 due to the diffuse reflection phenomenon due to the pattern.

That is, it can be seen that Example 1 has relatively excellent gloss among the high-gloss pattern films 1 for vehicles according to an embodiment of the present invention.

5 schematically shows the impact resistance test results of the high-gloss pattern film 1 for a vehicle and a comparative example according to embodiments of the present invention.

In this experiment, the impact resistance test was performed using the Gravelometer test equipment. This test can confirm how much the product can be protected when an impact is applied to the surface of the film using a weight attached to the equipment.

5(a), 5(b), and 5(c) schematically show the impact resistance test results of Examples 1, 2, and Comparative Example 1, respectively.

As shown in Figures 5 (a) and 5 (b), Examples 1 and 2, the first base layer 120, and the second base layer 310 intrinsic elasticity, and the film by the restoring force It appeared undamaged.

On the other hand, as shown in Fig. 5(c), Comparative Example 1 was made of a PVC material without elasticity and restoring force, so that the film was severely damaged.

As described above, it can be determined that Examples 1 and 2 according to the present invention have very excellent shock absorption performance. In this case, the first base layer 120 and the second base layer 310 of Examples 1 and 2 include thermoplastic polyurethane, and the base layer of Comparative Example 1 includes PVC.

That is, since the first base layer 120 and the second base layer 310 are formed of thermoplastic polyurethane, the impact resistance of the high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention can be improved. .

6 schematically shows the scratch resilience test results of the high-gloss pattern film 1 for a vehicle and a comparative example according to embodiments of the present invention.

In this experiment, scratches were generated on the surface of the film with steel wool (#0000) using a rubbing test equipment under the conditions of 80 rpm and 200 reciprocations. After the scratch occurred, heat was applied to the surface of the film using a dryer to check whether the scratch was restored.

6(a), 6(b), and 6(c) schematically show the scratch resilience test results of Examples 1, 2, and Comparative Example 1, respectively.

As shown in Fig. 6 (a), and Fig. 6 (b), Examples 1 and 2 showed that all scratches were restored after applying heat with a dryer.

On the other hand, as shown in FIG. 6( c ), it was found that in Comparative Example 1, there was no self-healing layer 110 , so that all scratches generated on the film surface remained intact.

As described above, Examples 1 and 2 according to the present invention can effectively restore most of the scratches generated on the surface by the self-healing layer 110 having scratch restoring force.

That is, the high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention may self-restore the scratch by the self-healing layer 110 when a scratch occurs on the surface, thereby improving scratch resistance.

In addition, according to the results of FIGS. 5 and 6 , it can be determined that the high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention can effectively protect the vehicle paint surface from external impact. On the other hand, in Comparative Example 1, it may be determined that the paint surface of the vehicle cannot be protected from external impact.

7 schematically shows a water repellency test result of a high-gloss pattern film 1 for a vehicle and a comparative example according to embodiments of the present invention.

In this experiment, a droplet of the same mass was dropped on the surface of the film using a micropipette, and the shape of the droplet formed on the surface was observed.

7(a), 7(b), and 7(c) schematically show the water repellency test results of Examples 1, 2, and Comparative Example 1, respectively.

As shown in Fig. 7(a), the water droplets falling on the surface of Example 1 were found to have a round shape. That is, it can be confirmed that Example 1 exhibits excellent water repellency.

In addition, as shown in Fig. 7(b), the water droplets falling on the surface of Example 2 were found to have a relatively spread shape compared to Example 1. In the case of Example 2, a water repellency similar to that of Example 1 is implemented by the self-healing layer 110 , but as the self-healing layer 110 is coated on the pattern layer 200 , it is formed on the pattern layer 200 . It can be determined that the water repellency is relatively decreased as the pattern is slightly raised upwards.

On the other hand, as shown in Fig. 7(c), the water droplets falling on the surface of Comparative Example 1 were found to have an elongated shape. In the case of Comparative Example 1, it can be seen that there is no self-healing layer 110 on the surface, indicating a relatively low water repellency.

As described above, Examples 1 and 2 according to the present invention may have excellent water repellency by the self-healing layer 110 formed on the surface. That is, it can be determined that the high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention has improved water repellency by the self-healing layer 110 to effectively protect the painted surface.

8 schematically shows the adhesion retention test results of the high-gloss pattern film 1 for a vehicle according to an embodiment of the present invention and Comparative Examples.

In this experiment, each film was sampled in the size of 2.5cm*19cm and attached to the same position. After that, the center of each film was cut with a knife to check the holding power of the adhesive for 24 hours.

8(a), 8(b), and 8(c) schematically show the adhesion holding force test results of Example 1, Comparative Example 2, and Comparative Example 3, respectively.

As shown in Fig. 8(a), Example 1 exhibits excellent adhesion retention. This can be determined as a result of not directly injecting a color into the adhesive layer 321 of Example 1, so that the physical properties of the adhesive layer 321 are stable, and the color layer 322 serves as a primer.

In addition, as shown in FIG. 8(b), in Comparative Example 2, it can be confirmed that peeling occurred between the substrate layer and the pressure-sensitive adhesive. It can be determined that the adhesion between the base layer and the adhesive layer 321 is reduced as the color is directly added to the base layer including the thermoplastic polyurethane.

On the other hand, as shown in FIG. 8(c) , it can be seen that in Comparative Example 3, there was a large gap between the cut surfaces. It can be determined that the physical properties of the adhesive layer 321 are deteriorated as a color is realized by adding a dye to the adhesive layer 321 .

That is, when Comparative Examples 2 and 3 are constructed in a vehicle with many curved portions on the exterior of the vehicle, such as a sports car, the film may be lifted or the pressure-sensitive adhesive may be transferred.

As such, in Example 1 according to the present invention, the adhesion retention of the high-gloss pattern film 1 for a vehicle can be improved by adding a color pigment to the color layer 322 to implement a color.

According to an embodiment of the present invention, by forming a self-healing layer made of a material having high elasticity, the scratch resistance and water repellency of the high-gloss pattern film for vehicles can be improved, thereby effectively protecting the painted surface. can
