The invention discloses coloring layer
coating suitable for silver alumite
hot stamping foils and a preparation method thereof. Paint films of silver alumite
hot stamping foils in the prior art are prone to
efflorescence; in gold
stamping, the defects of gold flying,
powder falling and the like are prone to happening; thus,
hot stamping quality and a production efficiency are affected. The coloring layer
coating disclosed by the invention is prepared from the following raw materials in parts by weight: 15 to 25 parts of
thermoplastic methacrylic resin, 1 to 5 parts of
chloride-acetate resin, 1to 8 parts of
styrene-
maleic anhydride copolymer, 1 to 10 parts of
cellulose acetate
butyrate, 1 to 10 parts of methyl
isobornyl acrylate, 1 to 5 parts of
impact modifier and 50 to 70 parts of
solvent. According to the coloring layer
coating disclosed by the invention, the
impact modifier is added into the formula ingredients, so that paint film
toughness is effectively improved; meanwhile, the coloring layer coating has the characteristics of moderate
viscosity, good adhesion with aluminum
layers, simple production technology easy to control, stable quality, convenience in long-time storageand the like; a coloring layer paint film of alumite containing the coloring layer coating has the characteristics of high glossiness, large
hardness,
toughness,
wear resistance and the like.
