Abstract

The invention relates to an ultraviolet light solidified waterproof printing ink, which comprises the following ingredients, using the total weight of the printing ink as reference, 13%-16% of water-soluble monomer, 15%-21% of water-soluble resin, 21%-25% of hydrophobic monomer, 7%-12% of hydrophobic resin, 1%-3% of dispersing agent, 5%-10% of photoinitiator, and 22%-32% of additive. A formula of the invention can reach balance between hydrophilism and hydrophobicity, wherein after UV crosslinking solidification, hydrophilic monomers and hydrophilic resin can absorb ink coating; and at the same time, the hydrophobic monomers and the hydrophobic resin form a hydrophobic coating after solidification, so that the ink is waterproof.

Description

technical field [0001] The invention relates to an ink composition, in particular to a printing ink applied to a printable optical disc. Background technique [0002] Printable ink is to print a layer of ink-absorbing coating on the surface of the disc and other plastic surfaces by silk screen printing. The coating is water-absorbent, so that a beautiful disc surface can be printed with a printer. [0003] The disc printable ink in the prior art is mainly to add white carbon black with good water absorption to water-based UV varnish. Although the printable ink has good printing effect, it is not waterproof. In this way, when the individual pattern printed on the surface of the CD or the color of the commemorative photo comes into contact with water droplets or is accidentally knocked over by the splash of water from a drink glass, it is prone to fading and blurring. Contents of the invention [0004] The technical problem to be solved by the present invention is to provi...
