Problems solved by technology

Water-based compositions in solvent-based compositions have the problem of slow printing speed resulting in low production efficiency
In order to meet the requirements of environmental protection and high production efficiency, the field has developed and improved compositions containing epoxy resin as the base resin and basically using no solvents, but there are still deficiencies in the later performance, such as only adhering to a single matrix material good sex

preparation example Construction

[0046] Corresponding to the above-mentioned pigment dispersion, the present invention provides a preparation method of the pigment dispersion, comprising the steps of:

[0047] (1) Weighing pigment, dispersing aid and dispersing monomer in proportion, for subsequent use;

[0048] (2) Add the dispersing aid to the dispersing monomer, stir with a homogenizer until the dispersion is uniform, add the pigment and dispersing beads within 10 minutes, and then continue stirring until the cumulative particle size distribution number D90 and pH value of the pigment dispersion meet the requirements , stop stirring, and filter out the dispersed beads to obtain the pigment dispersion of the present invention.

[0049] As the medium used in the dispersion treatment, the dispersion beads can be selected from: ceramic microspheres such as zirconia, polymer balls such as polyethylene and nylon, and metal balls. From the viewpoint of abrasiveness, the dispersed beads are preferably zirconia mi...

specific Embodiment approach

[0142] The present invention will be described in further detail below in conjunction with specific examples, but they should not be construed as limiting the protection scope of the present invention.

Embodiment 19-42

[0173] ①Use the pigment dispersion obtained in Examples 1-6 to prepare a color density of 50% k.

[0174] According to the formula shown in Table 5, under the condition of 20-30°C, pre-mix cationic polymerizable compounds B1, B2, cationic photoinitiator C, and sensitizer respectively, and then mix the raw materials according to B1, B2, C , sensitizer, pigment dispersion, leveling agent BYK307, and defoamer BYK055 are added to the constant temperature and pressure reactor in sequence, and the mixer is used at 1500-2000rpm under the condition of yellow light (that is, a safety light that will not trigger the reaction) Stir under low pressure, and when the mixed solution is a homogeneous mixture by visual inspection, filter through a 5 μm filter to obtain the radiation-curable composition of Examples 19-24 of the present invention.

Abstract

The invention discloses a pigment dispersion body, an application of the pigment dispersion body, and a radiation curing composition containing the pigment dispersion body. The radiation curing composition does not need to use a volatile solvent, is environmentally friendly, has excellent applicability to printing on plastic films, can be quickly cured to show excellent production efficiency, andcan form a multifunctional cured layer with excellent chemical resistance, scratch resistance, adhesion fastness with various base materials, traceability in the shrinkage process and the like after being cured.

Description

technical field [0001] The invention relates to the technical field of pigment and radiation curing, in particular to a pigment dispersion and its application in a radiation curing composition, and the radiation curing composition containing the pigment dispersion. Background technique [0002] Plastic bottles (such as PET bottles, etc.), metal bottles (such as iron cans, aluminum cans, etc.), glass bottles (tea beverages, etc.) that are widely used as liquid containers in the existing market are usually attached with plastic labels for Indicative or decorative purposes, in this type of plastic labels, shrink or stretch labels with good decorative and processability are often used, the manufacture of these labels usually includes coating or printing on the surface of the composition, In order to impart decoration, better processability and other functions through printing patterns. [0003] Existing printing compositions usually contain large amounts of organic solvents, an...
