Abstract

The invention discloses a photosensitive ink material and a technological process for applying the prepared photosensitive ink material to printing. The photosensitive ink material is prepared from components in percentage by weight as follows: 30%-60% of photosensitive resin, 30%-50% of pigments, 4%-8% of a photoinitiator, 5%-10% of a diluent and 1%-5% of an aid. The photosensitive ink material is applicable to color spraying or inkjet systems of 3D curved glass frames, and on the basis of no increase of construction difficulty, the negative effect of a curved surface on the exposure imagingeffect is reduced as far as possible. On the basis of the special requirements of photosensitive ink for printing of 3D curved glass cover plates, various key raw materials are designed and synthesized and are used for a formula of the photosensitive ink, on one hand, the key raw materials are used for matching a production process, on the other hand, the key raw materials are used for matching acuring process, and more importantly, the ink pattern effect, the environmental tolerance of cured patterns and other properties are improved.

Description

technical field [0001] The invention relates to an ink material, in particular to an ink material used for pattern printing on curved glass. Background technique [0002] The difficulty of graphic printing on 3D curved cover glass lies in changing from flat printing to curved surface printing. The higher the radius of curvature of the glass, the more challenging the pattern printing will be. At present, the graphics and text printing process similar to the front 3D curved cover glass of Samsung edge series mobile phones in South Korea inherits the thermal transfer technology that Samsung mobile phones have always liked to use on high-end models. The graphics and text printing process with the most rate loss has increased the difficulty of processing. At the same time, many of the core process parameters are jointly developed by Samsung and its suppliers, which are unique to Samsung and difficult to replicate in the industry. [0003] Recently, Corning Corporation of the Un...
