Abstract

The utility model relates to a rainbow film having multi-way changing light lines. The utility model comprises an overlapping layer, and a plurality of ultra thin layers are stacked and compounded, which forms the overlapping layer. The thin layers are respectively made of different transparent plastic materials and have different refractive indexes. At least one surface of the overlapping layer is provided with myriad different lines. Different pitches and line surface angles are arranged between the lines. The utility model leads each line to reflect different shapes and colors of bright lines following different viewing angles. Because the overlapping layer which is composed of a plurality of thin layers which are overlapped is arranged on each line, myriad thin and uniform bright colorful points can be formed in line colors, and compared with common single plain type bright lines, the utility model is soft and beautiful.

Description

Rainbow film with multi-way changing light line

The utility model relates to a kind of rainbow film, relates in particular to a kind of rainbow film with multi-way changing light line.

The embossing of logic light line early sees present so-called tinfoil paper and draws, that is, the logic ridge design is compressed on the aluminium foil applying paper,, can produces the variation and the special light line decorative effect of each angle different pattern on aluminium foil surface because the decorative pattern reflection angle that extrudes is had nothing in common with each other.Its principle is as follows, as shown in Figure 1, if on aluminium foil 10, extrude multi-turn light line, for example, the lines in the first lap 1 are straight line, and the lines in second circle 2 differ from 30 degree than first lap, lines in the 3rd circle 3 differ from 30 degree than second circle 2 again, lines in the 4th circle 4 differ from 30 degree than the 3rd circle 3 again, as shown in Figure 2, and when watching this pattern, in a certain angle, can only see a circle wherein, remaining then be can't see, when angle changes, then see an other circle, therefore, if continuously during angle changing, then can continue and constantly see the mobile effect of pattern, certainly, the angle of each circle changes hour, and for example 5 degree are to 10 degree, and its variation effect will be more obvious.

The grown form of rainbow film, a kind of plastic film of being produced by U.S. Mearl company for example, it need not use any pigment and dyestuff, can reflect different line shape and color along with different viewing angles; But its light line that can produce is to be the planar light that a simple surface is reflected, and its line coloured silk is comparatively dull and stiff.

Shortcoming at the prior art existence, the purpose of this utility model is to provide a kind of rainbow film with multi-way changing light line, this rainbow film is composited by most thin layer, and respectively two two-phase laminations of this thin layer are respectively made with different clear plastic materials, make respectively to have different refractive indexes; And impression has the lines of multiple different deflection angle or pitch at least one surface of lamination, makes each lines along with different viewing angles, reflects different line coloured silk and color.

For achieving the above object, the utility model is achieved through the following technical solutions: a kind of rainbow film with multi-way changing light line, comprise by most thin layer the folded mutually lamination that is composited, and the adjacent layer of thin layer each make with the clear plastic material of different refractivity; It is characterized in that: there is the lines of multiple different directions or pitch at least one surface of this lamination.

Plastic material is tygon, polypropylene, Polyvinylchloride or polystyrene.

Pitch is between 0.05 to 0.5 millimeter.

The one side of lamination is fitted with one deck backing at least.

Backing is formed of material or plates such as low PP, PE, PVC, PET or PS.

By the utlity model has the rainbow film of multi-way changing light line, overcome the shortcoming of prior art, reached the purpose of above-mentioned creation, the utility model is stamped in above-mentioned logic light line on the rainbow film and makes, can utilize the MULTIPLE COMPOSITE structure of rainbow film, make this light line have the line coloured silk that countless trickle luminous points form of one's own, present the visual impression of more soft grace.

The utility model is described in further detail below in conjunction with drawings and the specific embodiments.

Fig. 1 is the tinfoil paper applying recto lines form that is suppressed with logic light line;

Fig. 2 is the cross-sectional view of the tinfoil paper applying paper of Fig. 1;

Fig. 3 is the processing synoptic diagram by embossing machine compacting the utility model rainbow film;

Fig. 4 is the cross-sectional view with rainbow film of multi-way changing light line of the present utility model, and each lines has different reflection angles and pitch.

The utility model be as above-mentionedly impress logic light line on the mutually stacked at least one surface that is compounded to form a lamination rainbow film of institute as thin as a wafer by multilayer and make.According to the rainbow film with multi-way changing light line of the present utility model, its method for making is to produce the egative film of required pattern with computer printing, make the plane embossing plate with general plate-making etching method again, or directly make knurling tool 31, rainbow film can be separately or with other backing 21 (for example: applying paper, PP plate or film, PE plate or film, and the plate or the film of other plastic materials such as PVC, PET, PS) fit, compression moulding in various forms of embossing machines (Embossing machine) again.

As shown in Figure 3, in the utility model one embodiment,, at least one surface pressure of rainbow film 20 is made the lines that contains a plurality of different tropisms by above-mentioned embossing machine 30; So, because rainbow film includes most thin layer, each makes with the clear plastic material of different refractivity this thin layer again, make at least one surface of lamination rainbow film contain most lines of consolidating different directions or pitch 25, the width of pitch 25 is roughly between 0.05 to 0.5 millimeter (as shown in Figure 4).Above-mentioned rainbow film can be made by transparent plastic material, such as: tygon, polypropylene, Polyvinylchloride or polystyrene.

So, be shaped on the rainbow film of logic light line in above-mentioned surface pressure, when different directions is observed, can produce difference and look light line mutually; And because the formation of this light line is to come free most thin layer institute rainbow film of folded formation mutually, in the light line, be evenly distributed and imperceptible little luminous point, bringing up a kind of uniqueness and soft honorable vision is more graceful than traditional one plane type light line, really is a more excellent light line that advances.
