Description

Safety certificate card

Technical Field

The utility model relates to a safety certificate card field especially relates to a thermoprint membrane and safety certificate card.

Background

With the improvement of living standard of people, the social requirement on the optical anti-counterfeiting decoration of the security card is continuously improved. In the prior art, the security card anti-counterfeiting film pattern is mainly manufactured by an embedded, Overlay and Patch laser card base process. The reflection layers of the three anti-counterfeiting film manufacturing processes are all transparent, so that the light transmittance of the base film is influenced, the brightness of personalized information is reduced, and the anti-counterfeiting identification performance and the attractiveness of the security card are further influenced. Meanwhile, the security card is generally manufactured in an embedded processing mode, and the embedded security card with a high-light-transmittance reflecting layer is difficult to manufacture at present, mainly because the micro-light nanostructure information patterns are easily damaged at high temperature and high pressure in the card manufacturing process.

Therefore, at present, a new security certificate card is required to be manufactured, so that the certificate has a strong brightness and light transmission effect, normal reading of a certificate card chip is not affected, and the requirements of environmental protection and attractiveness are met.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art, the utility model provides a thermoprint membrane and safety certificate card has solved the problem that current safety certificate card base film luminousness is low and read card inefficiency.

In order to achieve the above purpose, the utility model discloses a following technical scheme realizes: the utility model provides a security card, includes the basic card body, information structure layer and bears the seal film, the information structure layer is located between the basic card body and the seal film, the information structure layer includes public information layer, has information layer, reflection stratum and the articulamentum of receiving optical structure pattern a little, public information layer sets up on the information layer, the information layer sets up on the reflection stratum, the first face of articulamentum meets with the reflection stratum, the second face of articulamentum meets with the seal film.

Preferably, the medium of the reflecting layer is Al, Cu, Ag or SiO₂MgF and ZnS.

Preferably, the micro-nano optical structure pattern of the information layer is provided with grating stripes with different widths and directions on a microscopic level.

Preferably, the connecting layer is a hot melt adhesive layer, a coupling layer or a pressure-sensitive adhesive layer.

The utility model discloses possess following beneficial effect:

1. increase card base film luminousness: the reflecting layer medium is positioned below the information layer so as to improve the reflection efficiency of the micro-nano optical structure pattern of the card information layer and increase the brightness;

2. the card reading efficiency is improved: the area of the reflecting layer on the micro-nano optical structure pattern only occupies a small part of the card body, and the radio frequency signal of the chip in the card is not shielded, so that the reading of the chip is not influenced, and the card reading efficiency is improved;

3. the environment-friendly aesthetic property is improved: the manufacturing process of the security card is environment-friendly, the micro-nano optical structure with decoration and anti-counterfeiting characteristics is loaded on the security card, and the requirements of beauty and environment protection are met.
