Pigment foil and method of preparing the same

Abstract

The invention relates to a pigmentary foil and a production method thereof. The pigmentary foil comprises at least one PET membrane base, on which coloring layer material and adhesive layer material are coated orderly. The coloring layer material is prepared by grinding, mixing, wetting and dispersing acrylic resin, ethenoid resin, mica powder, chloroprene rubber, white wax, polyethylene wax, soylecithin, pigments and mixed solvent. The adhesive layer material is prepared by mixing, wetting and dispersing cellulose acetate, vinyl cellulose, polyvinyl butyral, chalking silicon dioxide, water and ethanol mixed solvent. A coating machine uses the coating manner of a polishing roller or an anilox roller to coat the coloring layer material and the adhesive layer material on the 6-20-micron PETmembrane base; and then the PET membrane base is dried under the temperature of 80 to 140 DEG C, thus obtaining the pigmentary foil. The pigmentary foil has the advantages of different colors, wide selecting range, automatic and continuous hot stamping process, little waste, cleanness without pollution, simple producing art and convenient operating method; moreover, the pigmentary foil can be transported and stored easily and can achieve patterns and wards in different colors.

Description

technical field [0001] The invention relates to a pigment foil for hot stamping on printed matter and a manufacturing method thereof, belonging to the technical field of hot stamping. Background technique [0002] The original marking on the surface of various substrates is mainly realized by printing process, but the printing process uses materials such as inks and organic solvents; these solvents, organic compounds (VOC) emitted by inks during the drying process, and alcohol wetting liquid The isopropanol contained in the paint and the volatile gas of the glazing paint all pollute the air and are harmful to human health. [0003] Pigment foil is an environmentally friendly product that can replace ink printing. It is suitable for hot stamping and marking on the surface of various substrates, including various ABS, PVC, PS, PC, PP, PE, OPP and other composite materials, soft and hard PVC, ABS, SAN, PET, PC, PS, PP, PE, etc.; all kinds of thin paper, cardboard, coated paper...
