The inclined surface 55 may include a plurality of inclined surface elements. The inclined surface 55 may be formed by connecting a plurality of inclined surface elements. In the removed decorative member 12 shown in FIG. 6, a circumferential inclined surface 55 is formed by a first inclined surface element 551, a second inclined surface element 552, a third inclined surface element 553, and a fourth inclined surface element 554. Of these inclined surface elements, FIG. 3 shows the first inclined surface element 551 and the second inclined surface element 552 that are separated from each other in the circumferential direction RD. The first inclined surface element 551 and the second inclined surface element 552 extend in a direction perpendicular to both the stacking direction LD and the circumferential direction RD.

[0088] The inclined surface 55 is inclined with respect to the stacking direction LD. FIG. 3 shows a first inclined surface element 551 and a second inclined surface element 552 inclined with respect to the stacking direction LD. In the first inclined surface element 551 inclined with respect to the stacking direction LD, the connection portion between the first inclined surface element 551 and the second surface 40b is farther from the second inclined surface element 552 in the circumferential direction RD than the connection portion between the first inclined surface element 551 and the first surface 40a.

The coloring material may be a dye, a pigment, or a combination of a dye and a pigment. The repair coating film 71 is formed by solidifying a repair paint applied to the filled decorative member 13. The repair paint may include a plurality of paints including different coloring materials. As will be described in detail later, the composition of the repair paint, i.e., the composition ratio of each of the plurality of paints included in the repair paint, may be adjusted according to the part of the decorative member 10 to be repaired.

[0092] In the repaired decorative member 15 shown in FIG. 3, the repair coating film 71 includes a portion that is overlapped with the filled decorative member 13 via the functional film 72. The functional film 72 is located between the filled decorative member 13 and the repair coating film 71 in the stacking direction LD. The functional film 72 may have various functions. The functional film 72 may have a function of improving adhesion between the filled decorative member 13 and the repair coating film 71. The functional film 72 may display a design together with the repair coating film 71. The functional film 72 may function as a base for the repair coating film 71. The functional film 72 may be colored. The functional film 72 functions as a base, thereby improving the design of the design displayed by the repair coating film 71. The functional film 72 may have both the above-mentioned adhesion improving function and the function as a base. The functional film 72 may include the above-mentioned resin cured product. The repair coating film 71 may be directly laminated on the surface 13a of the filled decorative member 13 without the functional film 72 therebetween.

[0093] As shown in FIG. 3, a surface film 73 may be further superimposed on the repaired decorative member 15. The surface film 73 constitutes the surface 15a of the repaired decorative member 15. The surface film 73 may be superimposed on the repair coating film 71 as shown in FIG. 3. The surface film 73 may be formed over a wider area than the repair coating film 71 as shown in FIG. 2.

[0095] In the repaired decorative member 15 shown in Fig. 2 and Fig. 3, the portion of the surface 13a having the uneven shape AS is covered by at least a surface film 73. In other words, in the repaired decorative member 15 shown in the figures, the surface film 73 covers the portion of the surface 13a having the uneven shape AS and the peripheral portion of the portion having the uneven shape AS. The portion of the surface 13a having the uneven shape AS may be covered by a repair coating film 71 as shown in Fig. 2. The repair coating film 71 may cover the portion of the surface 13a having the uneven shape AS and the peripheral portion of the portion having the uneven shape AS. The portion of the surface 13a having the uneven shape AS may be covered by a functional film 72. The functional film 72 may cover the portion of the surface 13a having the uneven shape AS and the peripheral portion of the portion having the uneven shape AS. By having the uneven surface 13a have the uneven surface AS, the adhesion of the repair coating film 71, the functional film 72 and the surface film 73, which come into contact with the uneven surface AS, to the filled decorative member 13 can be improved.

[0096] A description will be given of the operation of the illustrated repaired decorative member 15. Specifically, a method for repairing the decorative member 10 (damaged decorative member 11) shown in Figs.

[0097] In the example shown in Figures 4 and 5, the decorative member 10 includes a linear damaged area 19 in the middle portion 34c of the front bumper 34. A portion of the decorative sheet 40 is missing at the damaged area 19. In the illustrated damaged decorative member 11, the second sheet 42 is missing at the damaged area 19. In other words, in the illustrated damaged decorative member 11, the decorative layer 44 and the sheet surface layer 45 are missing. In the illustrated damaged decorative member 11, the resin layer 43, the decorative layer 44, and the sheet surface layer 45 are exposed at the damaged area 19. The first removal area 21 of the decorative member 10 is constituted by the portion where the decorative layer 44 and the sheet surface layer 45 are missing.

[0098] In the removal step, the decorative sheet 40 is removed from the peripheral region located around the damaged region 19 of the decorative member 10. In the removal step, the second sheet 42 is removed. In the removal step, the first sheet 41 may be removed. In the removal step, the adherend AB may be removed. In FIG. 8, the second removal region 22 is formed by removing the decorative sheet 40 and the adherend AB from the peripheral region. The removed decorative member 12 is formed by removing the decorative sheet 40 and the adherend AB from the peripheral region. In the example shown in FIG. 8, the removal region 20 is formed by the first removal region 21 and the second removal region 22. The peripheral region may be removed by applying a polishing device such as a sander or sandpaper such as waterproof paper to the decorative sheet 40 and the adherend AB.

[0099] In the illustrated removed decorative member 12, the adherend AB is exposed in the removed portion 20. The removed portion 20 is defined by the adherend AB and an inclined surface 55. The removed portion 20 is defined by the exposed adherend AB on the second side in the stacking direction LD. The removed portion 20 is defined by the inclined surface 55 in a direction perpendicular to the stacking direction LD.

[0100] 6 and 8, the removed portion 20 has a tapered shape in the stacking direction LD toward the exposed adherend AB. The dimension of the removed portion 20 in a direction perpendicular to the stacking direction LD decreases as the removed portion 20 approaches the adherend AB in the stacking direction LD. In the removed portion 20 shown in FIG. 8, the dimension of the removed portion 20 in the circumferential direction RD decreases as the removed portion 20 approaches the adherend AB in the stacking direction LD.

[0101] The removed decorative member 12 includes the inclined surface 55 described above. In the removed decorative member 12 shown in FIG. 6, the inclined surface 55 includes the first inclined surface element 551, the second inclined surface element 552, the third inclined surface element 553, and the fourth inclined surface element 554 described above. The inclined surface 55 has a circumferential first edge 55a that connects to the adherend AB, and a circumferential second edge 55b that connects to the second surface 40b of the decorative sheet 40. The first edge 55a and the second edge 55b extend in a direction perpendicular to the stacking direction LD. In the example shown in FIG. 7, the first edge 55a and the second edge 55b are spaced apart from each other in the circumferential direction RD. In the example shown in FIG. 8, the intersections of the first edge 55a of the inclined surface 55 and the cutting line of the removed decorative member 12 are shown as points P10 and P20. 8, points P12 and P22 are indicated as intersections between the second edge 55b of the inclined surface 55 and the cutting line of the removed decorative member 12. The inclined surface 55 faces in a direction away from the adherend AB in the stacking direction LD, that is, toward the first side in the stacking direction LD in FIG.

[0102] Incidentally, in a damaged decorative member, as shown in FIG. 5, a step may be generated by the end face of the decorative sheet facing the damaged area. In the damaged decorative member, when force is applied to the end face forming the step, the decorative sheet may peel off from the end face. When the decorative sheet peels off from the end face, the damaged area may expand. The expansion of the damaged area may cause a problem of further deterioration of the design of the damaged decorative member.

[0103] In contrast, in the illustrated removed decorative member 12, the decorative sheet 40 has an inclined surface 55 inclined with respect to the lamination direction LD. The inclined surface 55 reduces the step generated on the surface 12a of the removed decorative member 12 as shown in FIG. 8. This makes it possible to prevent the decorative sheet 40 from unintentionally peeling off from the inclined surface 55 even if a force is applied to the inclined surface 55 of the decorative sheet 40. Therefore, it is possible to prevent the design of the damaged decorative member 10 from deteriorating.

[0104] 6 to 8 includes a first portion 56 formed by the decorative sheet 40 and a second portion 57 formed by the adherend AB. The first portion 56 may be called a sheet inclined portion. The second portion 57 may be called an adherend inclined portion.

[0105] The first portion 56 shown in FIGS. 6 to 8 has a first end 561 connected to the first surface 40a of the decorative sheet 40 and a second end 562 connected to the second surface 40b of the decorative sheet 40. The first end 561 and the second end 562 extend in a direction non-parallel to the stacking direction LD. The illustrated first portion 56 has an intermediate portion 563 between the first end 561 and the second end 562. The intermediate portion 563 is located at the connection portion between the first sheet 41 and the second sheet 42. In the inclined surface 55 (first inclined surface element 551) shown in FIG. 7, the first end 561, the second end 562, and the intermediate portion 563 extending linearly are observed.

[0106] 7 includes a first first portion 565 formed by the first sheet 41 and a second first portion 566 formed by the second sheet 42. The first first portion 565 may be referred to as a first sheet inclined portion. The second first portion 566 may be referred to as a second sheet inclined portion.

[0107] 7 and 8, the length L56 of the first portion 56 is greater than the thickness of the decorative sheet 40. From the viewpoint of effectively suppressing peeling of the decorative sheet 40 from the inclined surface 55, an upper limit may be set for the ratio of the thickness of the decorative sheet 40 to the length L56 of the first portion 56. The ratio of the thickness of the decorative sheet 40 to the length L56 of the first portion 56 may be 0.70 or less, or 0.50 or less. The ratio of the thickness of the decorative sheet 40 to the length L56 of the first portion 56 may be 0.0010 or more, or 0.015 or more.

[0108] The "length L56 of the first portion 56" or the "length L56 of the sheet inclined portion 56" is measured by the following method. Consider a line segment that is perpendicular to the first end 561 and intersects the second end 562. An example of such a line segment is line VIII-VIII in FIG. 6. In the cross section of the removed decorative member 12 by this line segment, a first point that is the intersection point of the first end 561 and the line segment, and a second point that is the intersection point of the second end 562 and the line segment are obtained. The first point is exemplified by point P11 in the first inclined surface element 551 and point P21 in the second inclined surface element 552 shown in FIG. 8. The second point is exemplified by point P12 in the first inclined surface element 551 and point P22 in the second inclined surface element 552 shown in FIG. 8. The "length L56 of the first portion 56" is measured by pressing a ruler against the inclined surface 55 and measuring the distance between the first point and the second point. 8, the distance L56 between the first point P11 and the second point P12 corresponds to the length of the first portion 56 in the first inclined surface element 551. As a ruler for measuring the length of the first portion 56, a tape measure that satisfies the first grade of the grades specified in JIS B 7512:2018 (Microconvex 2m (NMY-20) manufactured by TJM Design Co., Ltd.) is used.

[0109] The length of the first portion 56 measured by the above method may be 3.0 cm or more, or 5.0 cm or less. The length of the first portion 56 may be 20 cm or less, or 15 cm or less.

[0110] In the removed decorative member 12, the "thickness of the decorative sheet 40" is measured at a position 20 mm or more away from the removed portion 20 of the decorative member 10. The thickness of the decorative sheet 40 is measured by observing the cross section of the removed decorative member 12 using an optical microscope.

[0111] In the first portion 56 shown in Fig. 7 and Fig. 8, the length L566 of the second first portion 566 is greater than the thickness of the second sheet 42. From the viewpoint of effectively suppressing peeling of the decorative sheet 40 from the inclined surface 55, particularly peeling of the second sheet 42, an upper limit may be set for the ratio of the thickness of the second sheet 42 to the length L566 of the second first portion 566. The ratio of the thickness of the second sheet 42 to the length L566 of the second first portion 566 may be 0.70 or less, or may be 0.50 or less. The ratio of the thickness of the second sheet 42 to the length L566 of the second first portion 566 may be 0.0010 or more, or may be 0.015 or more.

[0112] The "length L566 of the second first portion 566" or the "length L566 of the second sheet inclined portion 566" is measured by the following method. Consider a line segment that is perpendicular to the second end portion 562 and intersects the middle portion 563. An example of such a line segment is line VIII-VIII in FIG. 6. In the cross section of the removed decorative member 12 by this line segment, a second point that is the intersection point of the first end portion 561 and the line segment, and a middle point that is the intersection point of the middle portion 563 and the line segment are obtained. As the second point, point P12 in the first inclined surface element 551 and point P22 in the second inclined surface element 552 shown in FIG. 8 are exemplified. As the middle point, point P13 in the first inclined surface element 551 and point P23 in the second inclined surface element 552 shown in FIG. 8 are exemplified. The "length L566 of the second first portion 566" is measured by pressing a ruler against the inclined surface 55 (first portion 56) and measuring the distance between the second point and the midpoint. In the removed decorative member 12 shown in FIG. 8, the distance between the first point P12 and the second point P13 corresponds to the length L566 of the second first portion 566 in the first inclined surface element 551. As a ruler for measuring the length of the second first portion 566, a tape measure (a micrometer 2m (NMY-20) manufactured by TJM Design Co., Ltd.) that satisfies the first grade in the grades specified in JIS B 7512:2018 is used.

[0113] In addition, the length L565 of the first first portion 565, i.e., the length L565 of the first sheet inclined portion 565, can also be measured in a similar manner. The length of the first first portion 565 is obtained by measuring the distance between the midpoint and the first point in the manner described above.

[0114] From the viewpoint of effectively suppressing peeling of the decorative sheet 40 from the inclined surface 55, a lower limit may be set for the angle between the inclined surface 55 and the stacking direction LD. The angle between the inclined surface 55 and the stacking direction LD may be 45° or more, 50° or more, or 60° or more. From the viewpoint of reducing the amount of removal of the decorative sheet 40 and efficiently repairing the decorative member 10, an upper limit may be set for the angle between the inclined surface 55 and the stacking direction LD. The angle between the inclined surface 55 and the stacking direction LD may be 175° or less, 90° or less, or 70° or less.

[0115] The "angle between the inclined surface 55 and the lamination direction LD" is measured by the following method. Consider a line segment that is perpendicular to the first edge 55a of the inclined surface 55 and intersects with the second edge 55b when viewed from the normal direction of the adherend AB at a certain point on the first edge 55a. An example of such a line segment is line VIII-VIII in FIG. 6. In the cross section of the removed decorative member 12 by this line segment, a first point is obtained that is an intersection point between the first edge 55a and the line segment, and a second point is obtained that is an intersection point between the second edge 55b and the line segment. Examples of the first point include point P10 in the first inclined surface element 551 and point P20 in the second inclined surface element 552 shown in FIG. 8. Examples of the second point include point P12 in the first inclined surface element 551 and point P22 in the second inclined surface element 552 shown in FIG. 8. The angle is measured between the normal direction of the adherend AB at the first point and a straight line connecting the first point and the second point that are connected to each other via the inclined surface 55. Examples of the straight line connecting the first point and the second point that are connected to each other via the inclined surface 55 include a straight line connecting the points P10 and P12 in Fig. 8 and a straight line connecting the points P20 and P22. The measured angle is the angle θ 1 , and the angle θ 2The "angle between the inclined surface 55 and the stacking direction LD" is the average value of the above-mentioned measured values ​​of the angle obtained by measuring ten different points on the inclined surface 55 by the above-mentioned method.

[0116] In the filling step, a filling composition 61 for forming the filler 60 is provided to the removed decorative member 12. Prior to the filling step, the surface 12a of the removed decorative member 12 may be degreased as a pre-filling degreasing step. In the degreasing step, a degreaser is applied to the surface 12a of the removed decorative member 12. In the degreasing step, the applied degreaser is wiped off from the surface 12a of the removed decorative member 12. The degreasing step can remove foreign matter such as oil and dust adhering to the surface 12a of the removed decorative member 12. This can improve the adhesion between the removed decorative member 12 and the filler 60. An organic solvent may be used as the degreaser. The degreaser may include one or more of isopropyl alcohol (IPA) and a hydrocarbon.

[0117] The filling composition 61 provided in the filling step may be in the form of a paste. The filling composition 61 may be a composition containing the above-mentioned thermosetting compound and a curing agent.

[0118] The filling composition 61 fills the removal area 20. The filling composition 61 contacts the adherend AB exposed in the removal area 20. The filling composition 61 contacts the inclined surface 55 of the decorative sheet 40. The filling composition 61 may contact the second surface 40b of the decorative sheet 40 as shown in FIG. 9. The filling composition 61 is solidified to form the filling material 60. The filling composition 61 may be solidified by curing. In the filling composition 61, the thermosetting compound may react with the curing agent to cure the thermosetting compound at room temperature. In this manner, a filled decorative member 13 including the filling material 60 is formed.

[0119] In the example shown in FIG. 3 and FIG. 9, the filler 60 (filling composition 61) is in contact with the inclined surface 55 of the decorative sheet 40. The filler 60 is in contact with each layer of the decorative sheet 40 exposed at the inclined surface 55. Since the decorative sheet 40 having a layered structure has the above-mentioned inclined surface 55, the area where the filler 60 contacts each layer of the decorative sheet 40 increases in the filled decorative member 13 and the repaired decorative member 15. The filler 60 contacts each layer of the decorative sheet 40 exposed at the inclined surface 55, so that the movement of each layer of the decorative sheet 40 in the stacking direction LD relative to other layers can be suppressed. This makes it possible to suppress peeling between layers of the decorative sheet 40 having a layered structure at the inclined surface 55.

[0120] The surface 13a of the filled decorative member 13 may be polished. By polishing the surface 13a, the filler 60 located on the decorative sheet 40, i.e., on the first side of the decorative sheet 40 in the stacking direction LD, may be removed. By polishing the surface 13a of the filled decorative member 13, the second surface 40b of the decorative sheet 40 may be polished. In this manner, an uneven shape AS may be formed on the surface 13a of the filled decorative member 13.

[0121] A laminate 70 including a repair coating 71 is formed on the filled decorative member 13. Prior to the formation of the laminate 70, i.e., prior to the application of a repair paint to form the repair coating 71, the surface 13a of the filled decorative member 13 may be degreased as a pre-application degreasing step. In the degreasing process, a degreaser is applied to the surface 13a of the filled decorative member 13. In the degreasing process, the applied degreaser is wiped off from the surface 13a of the filled decorative member 13. The degreasing process can remove foreign matter such as oil and dust adhering to the surface 13a of the filled decorative member 13. This can improve the adhesion between the filled decorative member 13 and the laminate 70, and between the filled decorative member 13 and the repair coating 71. The degreaser may include one or more of isopropyl alcohol (IPA) and a hydrocarbon.

[0122] A functional film 72 is formed on the filled decorative member 13. The functional film 72 may be formed on the uneven shape AS of the filled decorative member 13 as shown in Fig. 3.

[0123] In the application process, the repair coating film 71 is formed on the functional film 72. In the application process, the repair paint forming the repair coating film 71 is applied on the functional film 72. Incidentally, in a decorative member including an adherend and a decorative sheet attached to the adherend, the decorative sheet may be attached to the adherend in a stretched state. By attaching the decorative sheet in a stretched state, the design displayed by the decorative sheet differs depending on the part of the decorative member. In order to ensure excellent design properties even in the repaired decorative member, the composition of the repair paint for repairing the repaired part differs depending on the part of the decorative member. However, information on the composition of the repair paint according to the part of the decorative member cannot be obtained, and an inappropriate repair paint may be mixed. The formation of the repair coating film by an inappropriate repair paint deteriorates the design of the repaired decorative member.
