Description

High-permeability direct-injection advertising color paste, ink and preparation method thereof

Technical Field

The invention relates to the technical field of advertisement media, in particular to high-permeability direct-injection advertisement color paste, ink and a preparation method thereof.

Background

With the development of advertising media technology, the technology of dipping, coating, and writing by adopting PVC material cloth is difficult to meet the requirements. Digital printing technology has achieved great success on conventional cloths, but difficulties still remain in the use of advertising cloths.

On the one hand, the advertising cloth generally has intersecting lines of longitude and latitude, and a small hole structure exists on the surface of the material, so that when light irradiates from the back and the front of the advertising cloth respectively, two visual effects can appear, namely whether a lamp is turned on in an advertising box or not, the visual effects are inconsistent, and confusion and misidentification of consumers can be caused.

On the other hand, the dye can be fully combined on the advertising cloth by adopting modes such as dipping, coating and the like, but the digital direct-spraying technology is easy to generate the phenomenon of 'white exposure', which is not obvious under natural light, but when the advertisement box is turned on, part of light rays are emitted from small holes, the phenomenon of uneven dyeing of the fiber of the advertising cloth is amplified, and the phenomenon of 'white exposure' is easy to generate under light.

Patent application CN106336734A discloses a digital color inkjet ink with 3D lines and suitable for vamp printing, which is prepared from the following ingredients in parts by weight: 2 to 25 percent of oligomer of polymer or copolymer containing carboxylic acid group (COOH), 35 to 65 percent of monomer, 2 to 10 percent of pigment, 2 to 10 percent of photosensitive initiator, 2 to 35 percent of solvent and 5 to 15 percent of additive containing pigment dispersing agent or physical property regulator. The scheme can rapidly solidify pigment color ink-jet ink by absorbing ultraviolet light, has good adhesive force, replaces organic solvent by a photo-solidifying adhesion mode to dissolve and infiltrate into a substrate for adhesion, reduces the use ratio of the organic solvent, reduces the harm of the organic solvent to the environment and human body, and has the advantages of folding, twisting and non-deforming of the three-dimensional pattern color.

Ink detection

The detection method comprises the following steps: the Lab color model is composed of three elements of brightness (L) and related colors a and b. L represents brightness, a represents a range from magenta to green, and b represents a range from yellow to blue. L ranges from 0 to 100, l=50, which corresponds to 50% black; the value ranges of a and b are from +127 to-128, wherein +127a is red, and the value ranges are green when the value ranges gradually transition to-128 a; in the same principle, +127b is yellow and-128 b is blue. All colors are composed of these three values that change interactively. For example, the Lab value of a block color is l=100, a=30, b=0, and the block color is pink.

The difference between two identical colors can be compared from Lab value and ΔE difference to determine the color difference, whereinWherein delta E is more than or equal to 0.5, which indicates that the two comparison samples have obvious chromatic aberration, and can be obviously judged by naked eyes, wherein the test color is that ink is printed and directly sprayed on a lamp box cloth, and then the comparison analysis is carried out by coloring after stamping for 10 seconds at 220 ℃.
