Problems solved by technology

[0003] However, due to the single anti-counterfeiting technology, there are still potential safety hazards
In order to further improve the anti-counterfeiting performance, personalized anti-counterfeiting feature elements such as photos, names, birthdays, blood types, etc. that can indicate personal identity information are added to the holographic anti-counterfeiting label after heat transfer through stamping and other subsequent processes. The protective layer only focuses on scratch resistance and physical and chemical properties, but ignores the impact resistance, resulting in the overall material of the holographic anti-counterfeiting label being hard and brittle, with poor toughness. Under high impact conditions, the holographic anti-counterfeiting label is broken and cannot be play a protective role

Abstract

The present invention relates to a protective layer composition and a product containing the same. A holographic anti-counterfeit label protective layer containing the composition not only has favorable physical depreciation and chemical corrosion resistance, but also has favorable shock resistance and better protective effect.

Description

technical field [0001] The present application relates to adhesive compositions and products containing the protective layer compositions. Background technique [0002] With the increasing frequency of various commercial activities, the issuance and usage of various bank cards, identification cards, information storage cards, and various membership cards or papers have increased. Strict security and anti-counterfeiting technical requirements are put forward. In high-end anti-counterfeiting products, thermal transfer technology is used to stably bond the holographic anti-counterfeiting image to plastic or paper to form a holographic anti-counterfeiting mark with heat-sensitive adhesive or pressure-sensitive adhesive. The bonding is firm, and the holographic image can be preserved for a long time. The holographic anti-counterfeiting image will cause irreversible damage to the overall structure of the holographic anti-counterfeiting mark, achieving the purpose of anti-counterf...
