Colored translucent printing ink

Abstract

A colored translucent printing ink comprises colored printing ink, glass oil, hardener and thinner. The weight ratio of the components is 50 to 10-40 to 25-40 to 10-20. The invention aims to provide a colored translucent printing ink which has the advantages of low cost and high visible light absorption rate and consequently changes the transmissivity of the visible light. When light source is absent or is weak, light can not permeate substrate material but can permeate and display pictures provided that strong backlight exists.

Description

technical field [0001] The invention relates to a translucent ink, which is printed on the surface of an object to show different transmittances by utilizing the absorption of light, so that the light cannot pass through when there is no light source or a weak light source The base material, but under the premise of a strong backlight, the light can pass through and show the purpose of the pattern. Background technique [0002] The application of glass touch screen is very extensive and popular. The control menu buttons of the touch panel are generally opaque in order not to affect the appearance when they are not in use. Normally, they are the same color as the surrounding black frame. Only when the operation button pattern effect is displayed, and the opaque treatment methods generally adopted are mainly divided into the following categories: 1. The method of vacuum coating or ion sputtering coating, 2. The method of pasting astigmatism sheet, 3. Imported Translucent oil....

AI Technical Summary

Problems solved by technology

However, in the first and second methods, the appearance effect shown when there is no light source on the back is poor, and the naked eye can directly see the operation pattern of the product under normal circumstances, which cannot achieve the normal hiding effect and affects the appearance of the product. Appearance, and the cost of the coating method is very high, and the efficiency is low. The third method, one is the high price and cost, which is not conducive to the low-cost requirements of the product, and the other is that the core technology of the product is monopolized by foreign suppliers, which is not conducive to domestic technology improvement. , the third is that the product color is single, which cannot meet the needs of diversified and personalized appearance colors
