Embodiment approach

[0025] The implementation method of the technical solution adopted in the present invention is as follows:

[0026] (1) Three-layer coating liquid: primer layer, silver-containing ink-absorbing layer, and back-adhesive layer;

[0027] a. The primer layer is water-based polyurethane with a viscosity of 1~5cp, which is used to improve the ink-absorbing layer

[0028] Bonding fastness between PVC card bases;

[0029] b. Ingredients and ratio of silver-containing ink-absorbing layer:

[0030] Adhesive: polyvinyl alcohol (PVA), the degree of alcoholysis is 87% to 89%, the degree of polymerization is about 2000, and the dosage is 4% to 6.5%;

[0031] Dispersant: cationic dispersant, dosage 1%-5%,

[0032] Silver paste: nanoscale water-based silver paste, dosage 1%-10%;

[0033] Fixing agent: one of polyacetamide, polyvinylamide, urea or a mixture of two or more of them, the dosage is 3%-6%;

[0034] Surfactant: one or a mixture of fluorine-containing cationic surfactant or noni...

Abstract

The invention discloses a silver card suitable for inkjet printing. The silver card suitable for inkjet printing comprises a PVC (Polyvinyl Chloride) substrate; a base glue layer is coated to the front surface of the PVC substrate, an argentiferous ink-absorbing layer is coated on the surface of the base glue layer, and a back glue layer is coated to the back surface of the PVC substrate. The silver card provided by the invention avoids precoating a silver layer on the substrate, but only directly disperses silver slurry in latex of the ink-absorbing layer and directly coats the surface of the base glue layer so as to once coat an argentiferous certificate card with vivid colors and luxury and noble feedings.

Description

technical field [0001] The invention relates to a printing silver card, more specifically, relates to a silver card suitable for inkjet printing. Background technique [0002] With the rapid development of inkjet printing technology and digital printing technology, card making technology has also been significantly improved, and the number of various cards on the market is also increasing. In recent years, high-end personalized cards have been favored by the card industry for their flexibility and diversification. With the pursuit of card color change and diversity, gold and silver cards and similar products have begun to enter our field of vision. [0003] At present, there are many kinds of personalized gold and silver certificate cards and similar products on the market, such as the "gold and silver film" disclosed in the Chinese invention patent (utility model patent) application number 00207382.x. Add a gold and silver layer, coat the transparent coloring film on the g...
