Problems solved by technology

However, due to the limitations of the production process and technology of the conventional anodized hot stamping foil adhesive, the transparency of the adhesive material is relatively biased. During the use process, fumed silica powder needs to be added, so that the color layer on the reverse side cannot develop color normally, and the double-sided color development is electrochemical. The manufacture and promotion of aluminum hot stamping foil has brought great difficulties

Abstract

The invention relates to transparent back glue used for a double-face color development hot stamping foil and solves a problem of influence on color development on the last one coating due to poor transparency of a coated back glue layer in the prior art. The transparent back glue includes, by weight, 5-18 parts of aqueous polyurethane resin, 5-10 parts of aqueous rosin-modified phenolic resin, 0-10 parts of aqueous amino resin, 0.1-0.5 parts of a defoamer, 0.5-2 parts of a film-forming aid, 0-2 parts of a wetting agent, and 60-120 parts of deionized water. The transparent back glue is free of addition of fumed silica powder into the glue material during usage, and has high transparency and good cutting property.

Description

technical field [0001] The invention relates to a special polymer material, in particular to a transparent back adhesive for double-sided color-developing anodized aluminum hot stamping foil with high transparency and good cutting performance without adding fumed silica powder during use. Background technique [0002] Double-sided color-developing anodized aluminum hot stamping foil is one of the anodized aluminum hot stamping foils that can display different (or the same) colors on the front and back of the pattern after hot stamping. It is widely used in hot stamping on the surface of various transparent substrates. The color effect of the hot stamping pattern enhances the aesthetics. However, due to the limitations of the production process and technology of the conventional anodized hot stamping foil adhesive, the transparency of the adhesive material is relatively biased. During the use process, fumed silica powder needs to be added, so that the color layer on the rever...
