A thermal transfer foil with a metallic pigment layer

Abstract

The invention provides a heat-transfer-printing foil with a metal pigment layer. The heat-transfer-printing foil comprises a base film layer, a peeling layer, a color layer, an aluminium-plated layer and an adhesive layer which are overlaid in sequence, wherein the color layer contains the metal pigment layer; the metal pigment layer comprises the following materials in percentage by weight: 8-15% of metal pigment, 72-85% of thermoplastic resin, 0.2-0.5% of a filler, 0.2-0.3% of a defoaming agent, 2-8% of a rheological additive and 1.8-6.7% of a dispersing and wetting agent; and the metal pigment layer comprises metal particles, an amorphous silicon oxide film layer adhered on the metal particles and organic carboxylic-acid metal salt adhered on the silicon oxide film layer. The heat-transfer-printing foil provided by the invention has the advantages that by multiple additives, the viscosity of the metal pigment layer and the metal glossiness of the whole color layer are improved, so that the combination of the metal pigment layer and other coloring layers is closer, the dropping of the metal pigment layer in the transfer-printing process is prevented, and the metal glossiness of the transfer-printing foil also can be effectively increased without influencing the whole color phase.

Description

technical field

[0001] The invention relates to the technical field of transfer printing, in particular to a thermal transfer foil with a metal pigment layer. Background technique

[0002] With the development of society, product competition is becoming more and more fierce. In order to attract consumers' attention and stimulate consumers' desire to buy, the packaging of commodities nowadays is becoming more and more bright and dazzling. In order to grab customers' attention, it is novel and unique. Packaging patterns with metal effects have become an important killer feature for merchants. The hot stamping technology of transfer foil can significantly increase the gloss and sparkle of product packaging, make its color bright and dazzling, and enhance the gorgeous and noble products. It has become an indispensable printing method in the packaging industry.

[0003] The most widely used transfer foil in the market is anodized aluminum foil. The transfer foil is generally com...
