[0060] Preparation of photocurable ink composition

[0061] The present application relates to a method for preparing the above-mentioned photocurable ink composition, which method includes providing a fluorine-containing photoinitiator described in general formula (I), a (meth)acrylic acid polymer, a reactive diluent, a colorant, a filler or Combination of other components; filter the composition under the condition that the ink composition becomes substantially uniform and has suitable viscosity and surface tension. The photocurable ink composition described above is then transferred to a media substrate, and once the ink composition is printed on the media substrate, light energy is applied to the ink composition with a light energy suitable for curing the photocurable ink composition. frequency and energy level.

[0062] The photocurable ink composition is transferred to a media substrate. The media substrate can be planar, can be smooth or rough, or have any other shape...

Abstract

The invention provides an active energy photo-cured printing ink composition and an application thereof. The active energy photo-cured printing ink composition comprises a (methyl) acrylate polymer, aphotopolymerization initiator, an active diluent and a colorant, wherein the photopolymerization initiator includes an initiator with a structure as shown in a formula (I). According to the special structure of the photoinitiator, a photosensitive resin composition containing the photoinitiator has good weather resistance, chemical resistance and photoinitiation activity, so that the active energy photo-cured printing ink composition prepared from the photoinitiator can effectively inhibit the problem of excessively fast curing. Meanwhile, the reaction between the initiator and the componentssuch as the (methyl) acrylate polymer, the photopolymerization initiator, the active diluent and the colorant is relatively complete, and the molecular weight of a polymer formed after curing is relatively large, so that the active energy photo-cured printing ink composition also has the advantages of being difficult to migrate, free of odor and good in surface dry performance.

Description

technical field [0001] The invention relates to the field of photocurable inks, in particular to an active energy photocurable ink composition and its application. Background technique [0002] Ink is a homogeneous mixture composed of colored bodies (pigments, dyes, etc.), binders, fillers, additives and other substances. It is mainly used in the printing and packaging industries and is one of the most important printing materials in the printing industry. Ink is divided into various types according to different printing methods. Active energy light-curable ink is a new type of environmentally friendly ink. Due to the characteristics of no solvent emission, high production efficiency, and fast curing, light-curable inks are widely used. [0003] Existing documents provide the application of different ink compositions under ultraviolet lamps, and other documents provide the application of different ink compositions under ultraviolet lamps, especially UV-LED light sources.
