Embodiment 1

[0116] Take any one of the P2 series of polymerizable birefringent materials such as: P2-1-04: 100 parts, and then add 0.3 parts of methoxyphenol and any one of the optical adjustment additives, such as S811: 50 parts to combine the above-mentioned composition The material is heated to 20°C-80°C and stirred at 1000rpm until the material melts into a molten paste.

[0117] Then add photoinitiator TPO: 3 parts, ultraviolet absorber UV-531: 0.5 part, conductive agent BZ-33: 0.01 part, release agent 1 part to the composition, heat and stir together in the above molten paste uniform.

[0118] After the materials are evenly stirred, the above combination is processed onto paper, PET, books, refrigerators, communication tools, and TVs by hot stamping, silk screen printing, gravure printing, etc., and then irradiated by UV light. After post-curing, a color-changing functional layer that can reflect blue-violet light is obtained, which can play a decorative role in giving daily necess...

Embodiment 2

[0120]Take any one of the P2 series of polymerizable birefringent materials such as: P2-1-04: 100 parts, hindered amine inhibitor 701: 0.4 parts, optical adjustment additive RS-1: 4 parts, MIBK: 500 parts The above-mentioned materials of the composition are stirred at 2000 rpm at normal temperature to form a transparent solution.

[0121] Then add photoinitiator 819: 3 parts, ultraviolet absorber phenyl salicylate: 0.5 parts, leveling agent Tween-20: 5 parts, EA series EA-15 conductive agent of Santuo Chemical in the above solution 1 part, Dow Corning hand feeling agent DC-18: 0.1 part is added to the composition, heated and stirred together, and filtered to obtain a ready-to-use solution.

[0122] The above solution is processed by inkjet printing process on paper, PC, PU, ​​PET and other substrates or on daily necessities refrigerators, TVs, millet bracelets, desktops, kitchen countertops, ceramic tiles, communication tool sheaths, and communication tools. On the shell of t...

Embodiment 3

[0124] Take any two of the P2 series of polymerizable birefringent materials, such as P2-1-10: 10 parts, P2-1-08: 90 parts, and then mix with hindered amine inhibitor 701: 0.4 parts, optical adjustment additive RS-2: 3 parts, mixed solvent 500 parts, photoinitiator 651: 4 parts, ultraviolet absorber UV-329: 3 parts, leveling agent Tween-80: 3 parts, natural propolis antibacterial agent 1 part, Dow Corning Hand feeling agent DC-21 and hand wax Lanco TF1778: 0.02 parts are added to the composition, and stirred together at room temperature at a stirring speed of 500-3000rpm to form a transparent solution.

[0125] After the above solution is filtered, it is processed onto PU, PET and other substrates or furniture, refrigerators, wireless communication phone casings, and TV casings by dip-dyeing technology to form a whole-surface pattern. After drying and UV irradiation, a color-changing cured functional layer is obtained. The functional layer has a reflection peak in the visible ...

Abstract

The invention relates to a coating composition. The coating composition comprises a polymerizable birefringent material and an optical adjusting assistant, and is formed by the polymerizable birefringent material, the optical adjusting assistant, a solvent, a processing aid and a use performance improving assistant. The polymerizable birefringent material is used as the main raw material, and theoptical adjusting aid is used as an auxiliary material, so a finally formed cured coating has optical anisotropy, and finally is processed into a functional layer capable of changing the color with the angle of incident light, so final daily necessities have the optical characteristic of Bragg reflection in a specific wavelength band of in the visible light range, and has the function of changingthe color with the angle; and the functional layer has the advantages of good durability, good weather resistance, good mildew resistance and good hand feeling performance, and enhances the use hand feeling of daily necessities.

Description

technical field [0001] The invention relates to the coating field, in particular to a coating composition. Background technique [0002] With the advancement of science and technology and the improvement of living standards, more and more daily necessities are used in people's daily life. The appearance of various daily necessities is increasingly affecting the sales and use of products. A product feature that can bring unique feelings to consumers can bring a significant competitive advantage to product producers, so the appearance decoration of daily necessities has attracted extensive attention from relevant practitioners. [0003] Traditional angle-changing materials include interference type, cholesteric type, and mica titanium type. Among them, interference type has been widely used in daily necessities such as hand-held smart communication tools, but it has problems such as complex coating process, low production efficiency and high price; mica Angle-dependent color...
