Embodiment 1
[0046] like Figure 4 As shown, its basic structure is as follows: film material / red dye layer / aluminum pigment layer / silicon dioxide buffer layer / adhesive-film cutting cavity and solvent core layer / adhesive film surface material.
[0047] Production steps:
[0048] Production of discoloration part A:
[0049] The first step: select the film material (base layer 1), such as 50um transparent PA.
[0050] Step 2: Apply the red dye layer (color ink layer 2), aluminum pigment layer (opaque layer 3), and silica buffer layer (buffer layer 6) in sequence; the red dye layer is the word "failure".
[0051] Step 3: Die-cut and ready for use.
[0052] Inspire the production of part B:
[0053] The first step is to coat or print a release layer on the film substrate (easily peelable layer 9), or partially hollow out the release layer (the hollowed out area is similar in size and corresponding to the solvent holding chamber). Optionally, a half-cut is made on the release layer near th...
Embodiment 2
[0059] like Figure 5 As shown, its basic structure is as follows: film material / red-green-blue dye layer / aluminum pigment layer / alumina buffer layer / adhesive-heat-sealing film cut into cavity and solvent core layer / heat-sealing cover layer .
[0060] Production steps:
[0061] The production of discoloration part A: the steps are the same as in Example 1, wherein the color ink layer 2 is a black layer composed of a red-green-blue dye layer, and the opaque layer 3 is printed with blue dye after printing the aluminum pigment layer. √” symbol.
[0062] Inspire the production of part B:
[0063] The first step is to coat or print a release layer on the film substrate (easily peelable layer 9), or partially hollow out the release layer (the hollowed out area is similar in size and corresponding to the solvent holding chamber). Furthermore, it can be considered to cut half through the release layer near the solvent containing chamber, so that the stickers in the subsequent proc...
Embodiment 3
[0069] like Figure 6 As shown, its basic structure is as follows: film material / blue nano-pigment layer / pearlescent pigment layer / corncob silicon buffer layer / adhesive-film cutting cavity and solvent core layer / adhesive film surface material.
[0070] Production steps:
[0071] Production of discoloration part A:
[0072] The first step: select the film material (base layer 1), such as 50um PET;
[0073] The second step: apply the blue nano pigment layer (color ink layer 2), pearlescent pigment layer (opaque layer 3), and corncob buffer layer (buffer layer 6) in sequence;
[0074] Step 3: Die-cut and ready for use.
[0075] Inspire the production of part B:
[0076] In the first step, the surface material with adhesive film is cut out and drained, and then laminated on the film substrate (easy to peel off layer 9) to form a solvent holding chamber;
[0077] Step 2: select diacetyl with a melting point of -3 to -4°C as a solvent material, and fill the diacetyl solvent mat...
