The method comprises first providing a winding film to serve as a carrier for the concealed image, then obtaining a pattern required to be concealed on the carrier for the concealed image through a heating and press printing method, further compositing the carrier for the concealed image after heating and press printing treatment onto a polarization material, lastly compositing a reflection layer onto one face of the polarization material without the carrier for the concealed image, and obtaining the polarization concealed image.
Description
Technical field
The present invention relates to polarised light application, particularly a kind of polarisation latent image and preparation method thereof, for product false proof, the detection of polarisation product etc.
Background technology
Polarised light is that the direction of light vector of light wave is constant, the light that just its size changes with phase place.Can there is the refraction of different angles during by different medium in light.When light can make special media that it 90 ° of refraction angles have occurred time, polarised light phenomenon (claiming again polarisation phenomenon) will occur by a kind of; This light being refracted is polarisation; This special medium, is called polarisation medium.
Polarisation phenomenon (polarised light phenomenon) early be it is found that and the marvellous natural phenomena of paying attention to.Current, polarized light property is widely used on photoelectricity screen.But in false proof field, although each state has many experts and scholars to study, achievement is very micro-.Have a u s company only and be Bao Lilai company of the U.S. and utilizing polarized light property to make hidden polarization test pieces many years ago, do polaroid glasses test for global polarisation sunglasses production and sales manufacturers, its polarisation test pieces is utilized print process making.The basic structure that print process is made polarisation test pieces is: will contain polarisation medium powder and make transparent ink and be printed on a side of light polarizing film (sheet), and make the dimensional printed chart layer that in light polarizing film, the upper naked eyes of local cover are difficult for seeing.Like this, in this light polarizing film, do not printing for once polarisation refraction of region of layer, and having the region that prints layer to produce the refraction of secondary polarisation.Then the polaroid back side conventional on photoelectricity screen is stamped to reflecting layer, a polarisation refraction has just formed black and white pattern with the refraction of secondary polarisation, thereby obtains testing effect.The shortcoming that print process is made polarisation test pieces has: need add a cover obscuring layer to eliminate printing vestige; Complex manufacturing technology, cost is high; Containing polarisation medium powder, to make transparent ink price high, is difficult for buying.
The Chinese patent literature of CN 100395568C adopts heat sensitive process to make the method for polarisation latent image, it is in the making of polarisation latent image, the plastic sheeting of selecting pulling method to produce is made polarized light image carrier, adopting laser engraving machine to do temperature-sensitive processing to polarized light image carrier during heating moves the molecule in heated region without thread, upset originally and produced with pulling method the characteristic that molecules align is neat, have polarisation medium, lose polarisation effect and become normal transparent film, then will be compound on polarisation reflector plate through the polarized light image carrier thin film of temperature-sensitive processing.But laser engraving machine is expensive, maintaining complexity, drop into excessive, high cost.
CN 101200157 A provide a kind of method of making polarized-light stealth pattern, comprise step: draw materials there is polarised light dielectric property plastic sheeting as polarized-light stealth pattern carrier; Described polarized-light stealth pattern carrier is sheared and put vacancy reason; The polarized light diaphragm of drawing materials; The polarized-light stealth pattern carrier of putting vacancy reason through shearing is pasted or is compound on described polarized light diaphragm; Again paste or the compound plastic sheeting with polarised light dielectric property in the polarized light diaphragm front that is pasted with polarized-light stealth pattern carrier.Its technique is comparatively complicated, high cost.
Therefore, provide a kind of technique simple, less input, and the polarized-light stealth image formation method that production cost is lower is the difficult problem facing in industry.
