Abstract
A kind of have transparent position and the film and/or the coating at the opaque position that tilts, and the method for manufacturing is with transparent sheet and opaque or reflectivity thin slice layering and is glued together, and then with each thin slice separately.This film and/or coating are favourable as anti-copy film or coating.
Description
The present invention relates to particularly the transparent material film or the coating of plastics matter, this film or coating be formed with many parallel to each other, basically equidistantly, with the opaque position that film or coating surface are arranged by same predetermined angle, making this film or coating is that the separated transparent and opaque thin slice that will alternately bank up is adhered to one another.
For example, U.S. Pat-A-3,887,742 have introduced some is used for preventing the film special of xcopy.These films are made up of plastics, for example its surperficial xsect is groove shape or serrated profile, first sloping portion on surface is black or by with respect to film surface or reflective with respect to the visual angle of the surperficial approximate vertical of the file of using in the following general photorepeater, transparent when second of surface tilts or vertical component is looked by the predetermined angle of view that forms with each surface, thus data on the file can be discerned easily.
Also introduced this anti-film that duplicates in the above-mentioned patent, utilize the prismatic projection of film surface and by means of the special reflection coefficient of prism material with respect to surrounding medium, by reflection the data on the following file can be identified under predetermined visual angle, and under the vertical angle of view, discern not come out, as in duplicating applied like that.
Making this class section and be the film that groove or serrate even surface energy play the branch light action, make it reach desired precision, is very complicated technically.Opaque position must be quite even, and must accurately be limited in shape.
The purpose of this invention is to provide a kind of film and/or coating, it manufactures simpler, can be used as anti-transfer sheet or anti-copy film, and cost is not too big.
United States Patent (USP) 3,542,789 introduced can be in order to produce some optical effects and to can be used on the trough of belt transparent sheet that needs restriction visual angle occasion.The example of this class application scenario is as follows: TV screen, traffic signals prevent that the measurement instrument device is reflective or dazzle the eyes, and one-way glass.
The circular polymer sheet that this thin slice is normally cut by the lamination raw material of forming from the polymkeric substance of transparent polymer and reverse lining action is made, and the polymkeric substance that plays reverse lining action also can comprise by means of pigment (for example carbon black) makes opaque the sort of polymkeric substance.It is in a huddle that each disk is alignd on an axle, cooling then, and the coating with the edge excises or divests again, so thin slice has just been made.
For reaching predetermined optical characteristics, can adjust the thickness of variant sheet material or thin slice in case of necessity.For reaching desired beam cross-section and visual angle, also can make each sheet material of banking up tilt before divesting operation aforesaid.
U.S. Pat-A-3 more describes a kind of manufacture process of thin slice in 707,416 in detail, and this thin slice can be seen some opaque positions of angled orientation on its xsect, and wherein being formed with cone angle is the taper oblique base rods of 5 degree to 50 degree.Above-mentioned U.S. Pat-A-3 has introduced the excision or the strip of these base rods in 524,789.
We find that above-mentioned purpose can realize by a kind of like this film or transparent material coating of particularly plastics matter, this film or coating be formed with many parallel to each other, basically equidistantly, the opaque position of arranging by same predetermined angle with film or coating surface, when making this film or coating, be that the separated transparent and opaque thin slice that will alternately bank up is adhered to one another.This film or coating be as the anti-copy film or the coating of file, is used for overlay file, shelters data under the visual angle of approximate vertical, under another predetermined visual angle, can see data.
Like this, a kind of good method that just will make special film is used on the diverse purposes, promptly as anti-copy film or coating.
" sheltering data " speech that uses among the present invention is meant that data is become be can't see, and discovery or identification are not come out, or are in floodage.
In fact, film or coating can contain pigment, particularly white pigments at each layer that forms the inclination position.Do the manufacture process of having simplified film or coating like this, and the user produces cordial feeling when adopting white pigments.But also can adopt the pigment or the mineral black of other color, can obtain same benefit aspect the anti-print effect.
Each layer that forms the inclination position also can design to such an extent that make its tool reflectivity, the design during particularly by means of metallic pigments.
In addition, each layer that forms reflection inclination position can or cover metallized thin slice by sheet metal and make.
The predetermined angle of each inclined surface is got the scope of about 30 degree to about 70 degree, and particularly about 45 degree to the scope of 60 degree is advisable.
The thickness that forms the opaque or thin layer at opaque inclination position is advisable for particularly about 10 microns to about 16 microns scope with about 0.1.
The gross thickness of film or coating is advisable for particularly about 100 microns with about 50 to about 300 microns order of magnitude.This provides desirable condition for the optics aspect.
The anti-copy film that contains film of the present invention or coating, its substrate film also should be with transparent being advisable, and its employed any cementing agent also should be transparent certainly.
Then on the surface of the data that records that the film or the coating at the opaque inclination of above-mentioned tool position is applied to file, promptly can be made into anti-xcopy of the present invention.
Anti-xcopy also can comprise above-mentioned film or coating, and the opaque lamella of film or coating forms, and the printed information of file then is printed on the surface of film or coating.Opaque thin slice should be very little compared with the contrast of printed information color, so that can see the data of printing under predetermined visual angle, and under the visual angle with respect to film or coating surface approximate vertical the data of printing sheltered.
Accompanying drawing 1 shows anti-copy film and remains the situation that the anti-file that duplicates combines, below the mutual relationship of geometric condition and optics aspect among the brief description figure.
S is film or the coating that has thin slice L, and thin slice L is called opaque inclination position, disposes with the α angle that the surface of coating S in transparent plastic material T becomes to be scheduled to.Coating S also can be a self-bearing type, can directly be configured in the case on the file D that contains data (for example character I).As shown in the figure, be equipped with equally also transparent substrate film F,, directly be configured on the file D to keep the transparent way bonding.Each thin slice L spacing do each other should equate basically, and should make with same angle [alpha].The thickness of figure floating coat uses " h " to represent with " s " expression, the thickness of substrate film F.
φ is the angle, effective aperture of city's pin photorepeater, greatly about the scope of 6 degree to 54 degree.The thickness of thin slice is " q ".
Can draw following calculated relationship thus:
do＝s（A-Y）
A=l/tan α wherein
Y=tan φ/2; A＞Y wherein,
p＝s+h
Wherein p is the gross thickness of anti-copy film.
Y=tan φ/2 o'clock can draw the systematic parameter inequality by above-mentioned each angle
0.05≤Y≤0.5(6 ° or 54 °);
Comparatively ideal scope is 0.05≤Y≤0.1(6 ° or 12 °).
A=1/tan α＞Y 〉=0 o'clock by the 30.5 °≤α in angle≤73.2 °, draws 0.3≤A≤1.7
When coating thickness is S, suppose 5 microns≤S≤100 micron,
Can draw the scope of do thus:
Do=5 micron (0.3-0.05)=1.25 micron extremely
The scope that do=100 micron (1.7-0.1)=160 micron separates as thin slice.
The actual value of the thickness of coating or film should be
50 to 100 microns of s ≈ h ≈,
Thereby gross thickness is P=100 to 200 micron.
The thickness of each thin slice should be chosen about q=0.1 to 0.3do.Therefore, according to last value, the thickness of thin slice should be at q
1=0.125 micron to 0.375 micron, q
1=q(do
1) to q
2=16 microns to 48 microns scope, q
2=q
2(do
2).
In fact, owing to produce to prepare adopt city's pin film, thereby above-mentioned value is probably more near 16 microns, or at least greater than 0.1 micron.
In the accompanying drawing 1, arrow V represents the observed ray of approximate vertical, and data is sheltered by thin slice under this observed ray.Arrow 0 is illustrated in the visual angle that can see data I between each thin slice.This visual angle on causing corresponding to predetermined angle, i.e. the inclination angle of thin slice.
It is in practice, any that can thermoplastic form thereby need not film that cementing agent just can be bonded to each other all can be in order to produce the block blank as the parent of manufacturing anti-copy film of the present invention or coating.
If adopt the non-thermal plasticity film, then must adopt suitable translucent adhesive or take adhesive film at least to make the adequate measure of block blank.
As for substrate film F, to use transparent cementing agent equally.
Contact the present invention can make the used opaque thin slice of making in anti-copy film or the coating of inclination position L become opaque or reflective by following measure:
A) add pigment;
B) add dyestuff;
C) add pigment in the coating;
D) with spraying process or vapour deposition manufactured coating;
E) a minimum surface is anti-coarse;
F) with the photochromics exposure that is mounted in it;
G) with the photochromics exposure of laying.
Each thin slice preferably light color but also can be got any other color to white, reaches to be black and more or less to have a reflectivity.
Make block base substrate or can be the considerably less suitable thin slice of any transparency defective high, that influence transparency as the transparent sheet of substrate film.
The present invention relates to a kind of film and/or coating with transparent position and the opaque position of inclination, the method of making is with each transparent sheet and opaque or reflectivity thin slice layering and is glued together, and then with each thin slice separately (for example by excision or divest), this film and/or coating are favourable as anti-copy film or coating.So just can produce the sizable anti-copy film of demand economical and practically, and bring hope for the application prospect of anti-copy film.
