Abstract

The invention relates to the field of ink, in particular to anti-fading and anti-aging ink and a preparation method thereof. The printing ink comprises printing ink base liquid and microcapsules uniformly dispersed in the printing ink base liquid, and the microcapsule comprises a mineral pigment particle core and a modified acrylic resin shell wrapping the mineral pigment particle core. The pigment in the anti-fading and anti-aging ink prepared by the invention forms a stable microcapsule structure by coating the modified acrylic resin outside the extremely stable mineral pigment particles, so that the printing ink has super-strong color fading and aging resistance, and the color of a printed packaging product is enduring. The ink disclosed by the invention has the beneficial effects of fading and aging resistance, low VOCs (Volatile Organic Compounds), strong printing ink hydrophobicity and strong paper permeability, and is suitable for traditional offset printing and tap water offset printing.

Description

Technical field [0001] The present invention relates to the field of ink, and more particularly relates to a preparation method and aging ink fade. Background technique [0002] Printed materials widely used in daily life, a lot of people use food bags, food containers, sanitary towels, napkins, printed materials and other items may be in direct contact with the human body are mostly printed with other patterns, or text ad, and a coloring ink for printing , a colorant may be a pigment or a pigment. Ancient China materials can be divided into a colored pigment and a mineral pigment plants, wherein the plant major pigment a pigment ancient. Ancestor long mastered properties of various plant pigments, pigment plants when dyed, the dye molecule whose color is changed by bonding the fibers with the textile fibers affinity, despite the color of the sun washed, are not easy to off or rarely come off. Plant pigment is the use of natural flowers, grass, trees, stems, leaves, fruits, seeds...
