Rainbow mark manufactured by embodiment 3, including substrate 200,200 one side of substrate are equipped with molding chromatograph 100；
100 head end of molding chromatograph to end is successively arranged the first primary colors glue part 110, the second primary colors glue part 130 and
Three primary colors glue part 150；
The first primary colors glue part 110, the second primary colors glue part 130 and third primary color glue part 150 correspond respectively to three primary colors
A kind of middle color；
Color part 120 is laminated between the first primary colors glue part 110 and the second primary colors glue part 130 for first；Described second is former
Color part 150 is laminated between coloring agent part 130 and third primary color glue part 150 for second.
Glue part uses IR transparent adhesive tape.
The three primary colors are red, yellow, blue.
It is yellow that a kind of situation, which is the first primary colors glue part 110, and the second primary colors glue part 130 is red, described the
Three primary colors glue part 150 is blue；In order to make it easy to understand, being illustrated on this basis, do not have restriction effect；
Than as shown in Figure 2, from the side A to the side B；The side A is close to the first primary colors glue part 110, the side B close to the second primary colors glue part
130, in molding, the former material of the first coloring agent element 110 also can partially shift the side A arrival first and laminate 120 left side of color part, from
And make first to laminate color part 120 yellow former material gradually decreases from left to right, red former material gradually increases；
Since yellow and red fusion form orange, so that the gradual change chromatograph of yellow-orange-red colors is formed from the side A to the side B,
And it is orange also orange for gradual change, it is done certainly to right color and is gradually deepened；
Yellow is different with red former material fusion proportion, so that first laminates color part 120 and form yellow from left to right to red
Graduated colors.
For another situation herein in connection with content in Fig. 2, setting third primary color glue part 150 at this time is yellow, the second primary colors glue
Part 130 is red, and the first primary colors glue part 110 is blue；
From the side A to the side B；The side A close to the first primary colors glue part 110, the side B close to the second primary colors glue part 130, in molding, the
The former material of one coloring agent element 110 also can partially shift the side A arrival first and laminate 120 left side of color part, so that first laminates
Blue former material gradually decreases color part 120 from left to right, and red former material gradually increases；
Formation purple is merged with blue due to red, so that purple-red gradual change chromatograph of blue-is formed from the side A to the side B, and
And purple is also gradual change purple, is done certainly to right color and is gradually deepened；
Red and blue former material fusion proportion is different, thus first laminate color part 120 formed from left to right it is blue to red
Graduated colors.
The first primary colors glue part 110, first laminates color part 120, the second primary colors glue part 130, second laminates 140 and of color part
Third primary color glue part 150 is transparent material.
Described first, which laminates color part 120 and second, laminates 140 width L1 of color part as the 130 width L2 of the second primary colors glue part
40-50%.
Described first, which laminates the second primary colors glue described in color part 120 first primary colors glue and multilayer as described in multilayer, is overrided to form；
Described second, which laminates third primary color glue described in color part 140 second primary colors glue and multilayer as described in multilayer, is overrided to form.
