Dark electrochemical aluminium foil with applicable thermoprinting scope

Abstract

The invention provides a dark electrochemical aluminium foil with an applicable thermoprinting scope. The electrochemical aluminium foil comprises a carrier membrane, a release layer, an imaging layer, an aluminum plating layer and a glue layer, the imaging layer comprises the following components by weight percentage: 14.5-16% of amino-acrylic resin, 13-14% of methyl hydroxy modified acrylic resin, 5-7% of nitrocellulose, 37-40%of butanone, 24-26% of butyiate, and 4.5-5.5% of color powder; the imaging layer employs template roller printing with 180 meshes, and the dry coating amount is 1.26+ / -0.05 g / m<2>. According to the dark electrochemical aluminium foil, the coating apparent leveling effect of the imaging layer is good, the moulding effect is good, the moulding effect is good, the color aluminium combination fastness is high, moulding is carried out without coating the imaging layer with a layer of protective layer, the dark electrochemical aluminium foil is suitable for thermoprinting the patterns with small area or fine line patterns, the cost is saved, and the applicable thermoprinting scope is widened.

Description

technical field [0001] The invention relates to a transfer film, in particular to an anodized aluminum foil which is suitable for transfer printing and contains an aluminized layer, and more particularly relates to a dark-colored anodized aluminum foil with a wide range of suitability for ironing. Background technique [0002] Anodized aluminum foil is a hot stamping material made by adding a layer of metal foil on a film substrate by coating and vacuum evaporation. Anodized aluminum foil generally includes a film substrate, a release layer, an imaging layer, an aluminum layer and an adhesive. Layer, colored anodized aluminum foil is to add toner in the imaging layer, dark color, special color anodized aluminum foil due to the high content of toner in the imaging layer (mostly more than 5%), so there are generally poor coating leveling appearance, Problems such as poor molding performance and poor bonding fastness between the color layer and the aluminum layer lead to narrow...

[0002] Anodized aluminum foil is a hot stamping material made by adding a layer of metal foil on a film substrate by coating and vacuum evaporation. Anodized aluminum foil generally includes a film substrate, a release layer, an imaging layer, an aluminum layer and an adhesive. Layer, colored anodized aluminum foil is to add toner in the imaging layer, dark color, special color anodized aluminum foil due to the high content of toner in the imaging layer (mostly more than 5%), so there are generally poor coating leveling appearance, Problems such as poor molding performance and poor bonding fastness between the color layer and the aluminum layer lead to narrow limitations of hot stamping; in addition, due to the poor tolerance of the resin coating of the imaging layer to the toner, some toner is easily exposed on the surface of the imaging layer , leading to the adhesion of bare toner on the molded sheet during molding, resulting in poor molding effect, easy to stick plate, difficult to clean and other molding problems. The current method to solve this problem is to apply a protective layer on the imaging layer, but the coating The protective layer not only increases the cost, but also can only be applied to patterns with large hot stamping areas or thick lines; therefore, most of the dark and special color anodized aluminum foils currently on the market are ordinary anodized aluminum foils, and very few have laser effects of
