Black pattern 123, ink logo 123 and the second heat discoloration ink 122 are located at side by side in one layer of distribution, which covers
It is placed on 123 surface of the second heat discoloration ink 122 and ink logo.After variation of ambient temperature, second heat discoloration oil
Ink 122, at this point, can highlight ink logo 123, so as to improve aesthetic feeling, reaches decoration then by coloured bleach
Effect, and interest can be enhanced.
The ink logo 123 can be pattern, text, letter, number, any one or more than one in symbol
Combination.
The third structure: as shown in connection with fig. 4, the heat discoloration ink layer 12 is double-layer structure comprising at least one
It is covered in the ink logo 123 on 11 surface of plastic layer and is covered in 123 surface of ink logo and after temperature-sensitive by coloured
Second heat discoloration ink 122 of bleach, the PET hyaline layer 13 are covered in 122 surface of the second heat discoloration ink.This
Two heat discoloration ink 122 cover ink logo 123 when not changing colour, which cannot show
Come, after variation of ambient temperature, the second heat discoloration ink 122 is then by coloured bleach, at this point, ink logo 123 can be saturating
It crosses the second heat discoloration ink 122 and PET hyaline layer 13 highlights, so as to improve aesthetic feeling, achieve the effect that decoration, and
Interest can be enhanced.
The ink logo 123 can be pattern, text, letter, number, any one or more than one in symbol
Combination.
4th kind of structure: as shown in connection with fig. 5, the heat discoloration ink layer 12 is single layer structure comprising at least one
It by the first heat discoloration ink 121 for having discoloration coloured and is set to 121 periphery of the first heat discoloration ink after temperature-sensitive and feels
By the second heat discoloration ink 122 of coloured bleach after temperature, and the first heat discoloration ink 121 and the second heat discoloration ink
122 color before discoloration is identical, and the second heat discoloration ink 122 and the first heat discoloration ink 121 are located at is in side by side
One layer of distribution, the PET hyaline layer 13 are covered in 122 surface of the first heat discoloration ink 121 and the second heat discoloration ink.Often
Under rule state, the first heat discoloration ink 121 is identical with color of the second heat discoloration ink 122 before discoloration, works as temperature
After variation, which becomes another color from a kind of color, and the second heat discoloration ink 122 is
By coloured bleach after temperature-sensitive, the first heat discoloration ink 121 is highlighted with this, the pattern of the first heat discoloration ink 121 can
To be made into pattern, text, letter, number, any one or more than one combination in symbol reach so as to improve aesthetic feeling
The effect of decoration, and interest can be enhanced.
5th kind of structure: as shown in connection with fig. 6, the heat discoloration ink layer 12 be single layer structure comprising after temperature-sensitive by
There are the first heat discoloration ink 121 that discoloration is coloured and at least one to be set to 121 periphery of the first heat discoloration ink and feels
By the third heat discoloration ink 124 for having discoloration coloured, the first heat discoloration ink 121 and third heat discoloration ink after temperature
124 discoloring temperature is different, and the color before discoloration is identical, the third heat discoloration ink 124 and the first heat discoloration
Ink 121 is located at side by side in one layer of distribution, which is covered in the first heat discoloration ink 121 and third temperature-sensitive
124 surface of color shifting ink.Under conventional sense, the first heat discoloration ink 121 and third heat discoloration ink 124 are before discoloration
Color it is identical, since the discoloring temperature of the first heat discoloration ink 121 and third heat discoloration ink 124 is different, thus
After temperature change, the first heat discoloration ink 121 and third heat discoloration ink 124 show two different colors, with this
Different combinations of patterns is formed, so as to improve aesthetic feeling, achievees the effect that decoration, and interest can be enhanced.
Certainly, the heat discoloration ink layer 12 can also be other different structures, and this is no longer going to repeat them.
In conclusion the present invention can will be set to 11 He of plastic layer according to the heat discoloration ink layer 12 of temperature discoloring
Between PET hyaline layer 13, when variation of ambient temperature, the color of the heat discoloration ink layer 12 also can with the variation of temperature and
Variation, so as to improve aesthetic feeling, achievees the effect that decoration, and can enhance interest；Furthermore when switch generation is short-circuit or other
Phenomenon and when generating a large amount of heat, which can be transmitted on switch panel, at this point, heat discoloration ink layer 12 can change colour
(as red), has the function that warning with this, reduces the risk that safety accident occurs, the present invention is enabled to have extremely strong market competition
Power.In addition, PET hyaline layer 13 is shaped in 11 surface of plastic layer by in-mould injection technique and covers heat discoloration ink layer
12, not only stable structure, and heat discoloration ink layer 12 can be preferably protected, prevent heat discoloration ink layer 12 from being scraped
Flower improves aesthetics and service life.
Certainly, the above is only a specific embodiment of the present invention, be not to limit the scope of the present invention, it is all according to
The equivalent change or modification that structure, feature and principle described in scope of the present invention patent is done should be included in Shen of the present invention
It please be in the scope of the patents.
