Problems solved by technology

[0003] In the existing UV curing anti-etching ink composition, the main functional group contained in the molecule is that the ink composition of carboxyl group has poor alkali etching resistance; other ink compositions with better alkali etching resistance can reduce the carboxyl group. Functional groups are used to achieve this purpose. Although this improves the alkali etching resistance, the cured film formed by it has poor solubility in strong alkali solution and is not easy to be removed in the subsequent process.

Abstract

The invention provides an alkali-resistant UV curing etching resistant printing ink composite which contains strong lye solube resin, photosensitive initiator, photosensitive diluent and filler; wherein, the molecules of the strong lye solube resin contain at least one phenolic hydroxyl without carboxyl, and the strong lye solube resin is selected from one of the following compounds: (1) the compound which is obtained by the hydroxide radical of (methyl) acrylic acid hydroxy ester being epiphytically reacted with the hydroxide radical of phenolic acid; (2) the compound which is obtained by theepoxy group of (methyl) acrylic acid ethylene oxidic ester being reacted with the hydroxide radical of phenolic acid; (3) lye solube phenolic resin. The cured film formed by using the alkali-resistant UV curing etching resistant printing ink composite of the invention has good curing etching resistant property, has good solubility in alkali solution and is easy to remove film by alkali solution after being etched.

Description

technical field [0001] The invention relates to a UV curing alkali-resistant etching ink composition and application thereof. The ink composition can be applied to the production of printed circuit board circuits. Background technique [0002] The UV curing anti-etching ink composition has wide application in the fields of making single-sided printed circuit boards and inner-layer circuits of multilayer circuits. In the production process of printed circuit boards, the UV curable anti-etching ink composition is printed on the metal substrate, and after using an appropriate mask to form a cured film through photocuring, the substrate is etched with an etching solution, and then a strong alkali solution is used to etch the substrate. The cured film was removed to obtain a printed circuit board. Among them, according to different substrate materials, different acidic and alkaline etching solutions can be selected, and the UV curable ink composition used should have correspondi...
