Abstract

The invention discloses fixation rosin ink and belongs to the technical field of ink. The fixation rosin ink comprises epoxy resin, polymeric rosin, polyethylene glycol, Cuban glue, a dispersant, a fixation agent and a pigment. The fixation rosin ink contains the fixation agent component and can effectively improve the fixation properties.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a color-fixing rosin ink. Background technique [0002] With the rapid development of the printing industry, consumers' requirements for the quality of printed matter are also increasing, and the quality of ink, which plays a key role in printing quality, is very important. Ink is a homogeneous mixture composed of colored bodies (such as pigments, dyes, etc.), linking materials, filling (filling) materials, additives, etc., and the additives (ie additives) are added to improve the printability of the ink. Such as viscosity, adhesiveness, dryness, etc. [0003] Rosin is a non-volatile natural resin obtained from pine rosin through different processing methods. Its main component is abietic (rosin) acid, which contains a carboxylic acid group and two conjugated carbon-carbon double bonds. It can be esterified with glycerin, pentaerythritol and other polyols to form low-ac...
