Abstract

The invention discloses gradient printing ink, which is characterized by comprising the following components by weight: 40-60 parts of fluorescent ink; 30 to 50 parts of cured resin; 5-15 parts of a solvent. The fluorescent ink comprises the following components in parts by weight: 4-6 parts of yellow fluorescent powder particles of 20-25 [mu]m; 3-5 parts of red phosphor particles of 20-25 [mu]m;4-6 parts of green fluorescent powder particles of 20-25 [mu]m; 25 to 35 parts of high-transparency resin; 1-3 parts of a diluent; 1-3 parts of a curing agent. The invention also provides a preparation method and a printing method of the gradient printing ink. The gradient printing ink disclosed by the invention is sufficient in adhesive property, enough in firmness and wear resistance, good in anti-cracking degree and transfer effect and remarkable in gradient effect. Meanwhile, the invention further provides a gradient printing method of the gradient printing ink, the whole process is simple, a large amount of manual operation is not needed, the cost is low, and the gradient appearance effect is good.

Description

technical field [0001] The invention belongs to the technical field of ink, and in particular relates to a gradient printing ink and a gradient printing method. Background technique [0002] Since the liquid crystal in the liquid crystal display panel itself does not have luminescent properties, it is necessary to provide a backlight module for the liquid crystal display panel to provide the liquid crystal display panel with a planar light source with sufficient brightness and uniform distribution. The luminous effect of the backlight module will directly affect the visual effect of the liquid crystal display, which includes light guide plates, LED lamps, diffusers and the like. Backlight modules often suffer from uneven light emission, such as light spots, light holes, or cross-light phenomena. In order to improve the visual effects of liquid crystal displays, a common method in the prior art is to form a gradient effect on the surface, and the current method of forming a ...
