Detailed Description

The term as used herein:

"by 8230; \ 8230; preparation" is synonymous with "comprising". As used herein, the terms "comprises," "comprising," "includes," "including," "has," "having," "contains" or any other variation thereof, are intended to cover a non-exclusive inclusion. For example, a composition, process, method, article, or apparatus that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, process, method, article, or apparatus.

The conjunction "consisting of 8230% \8230comprises" excludes any unspecified elements, steps or components. If used in a claim, this phrase shall render the claim closed except for the materials described except for those materials normally associated therewith. When the phrase "consisting of 8230' \8230"; composition "appears in a clause of the subject matter of the claims and not immediately after the subject matter, it defines only the elements described in the clause; no other elements are excluded from the claims as a whole.

When an amount, concentration, or other value or parameter is expressed as a range, preferred range, or range defined by a list of upper preferable values and lower preferable values, this is to be understood as specifically disclosing all ranges formed from any pair of any upper range limit or preferred value and any lower range limit or preferred value, regardless of whether ranges are separately disclosed. For example, when a range of "1 to 5" is disclosed, the recited range should be interpreted to include ranges of "1 to 4," "1 to 3," "1 to 2 and 4 to 5," "1 to 3 and 5," and the like. When a range of values is described herein, unless otherwise specified, the range is intended to include the endpoints thereof, and all integers and fractions within the range.

In these examples, the parts and percentages are by mass unless otherwise indicated.

"part by mass" means a basic unit of measure indicating a mass ratio of a plurality of components, and 1 part may represent an arbitrary unit mass, for example, 1g or 2.689 g. If the parts by mass of the component A are a parts and the parts by mass of the component B are B parts, the mass ratio of the component A to the component B is expressed as a: b. alternatively, the mass of the A component is aK and the mass of the B component is bK (K is an arbitrary number, and represents a multiple factor). It is not to be misunderstood that the sum of the parts by mass of all the components is not limited to the limit of 100 parts, unlike the parts by mass.

"and/or" is used to indicate that one or both of the illustrated conditions may occur, e.g., a and/or B includes (a and B) and (a or B).

In an alternative embodiment, the material of the substrate layer may be PET (polyethylene terephthalate) or PC (polycarbonate).

In an alternative embodiment, the tinted oil in the tinted oil layer comprises an infrared light transmissive ink.

When the fluorescent ink is used, silk-screen textures including CD (compact disc) textures, triangular pyramid textures and the like are printed, the effect brought out by the textures is covered after film coating, the color of the ink is too thick, the color is simple, and the fluorescent ink has certain timeliness, so that the target effect cannot be achieved. The IR (infrared) ink can adjust the transparency of the ink, the gloss oil is adjusted to be a single color, the effect of filtering the wavelength of visible light is achieved, the color of the gloss oil can only be transmitted, then the light color ink is used for covering the bottom, and the problems existing in the prior art can be solved because only one light beam is transmitted, and the light of the light color ink, whether reflected or transmitted, is a color.

In an alternative embodiment, the light transmittance of the pigmented oil layer is 70-90%.

The reason why the transmittances are different is because the light has a slight and dark distribution on the color display. For example, the light green color can be selected to have a transmittance of 80%, and the light transmittance of the dark green color needs to be higher to be displayed as much as possible by white oil on the bottom of the cover. The transmittance plays an important role in this respect, being adjusted to the color of the tint.

Alternatively, the light transmittance of the colored light oil layer may be 70%, 80%, 90%, or any value between 70 and 90%. In an alternative embodiment, the light ink layer comprises a plurality of white ink layers and the dark ink layer comprises one or more black ink layers.

In an alternative embodiment, the white ink layer is provided with two or three layers.

The white printing ink layer can be the colour of outstanding transmission, and the brush three-layer can increase white effect, the setting on black printing ink layer, and one of them purpose is in order to make the diaphragm can reach the service standard of normal film, including the dyne value test, and can paste the gum.

In an alternative embodiment, the thickness of the light ink layer and the dark ink layer is each independently 6 to 8 μm.

In an alternative embodiment, the white ink layer and the black ink layer have the same thickness.

Optionally, the thicknesses of the light color ink layer and the dark color ink layer can be any value between 6 μm, 7 μm, 8 μm or 6-8 μm independently.

In an alternative embodiment, the colored varnish layer is the same color system as the electroplated layer.

Note that the same color system as used herein means that the colored varnish layer and the plating layer have the same or similar color and are in the same color system.

In an optional embodiment, the electronic cover further includes a substrate, and the membrane with a high brightness texture is disposed on a surface of the substrate.

Here, the substrate is one of a glass substrate, a ceramic substrate, a gem substrate, and a metal substrate.

In an alternative embodiment, the electronic product may be one of a mobile phone, a tablet computer, a watch, and a bracelet, but is not limited thereto.
