Problems solved by technology

However, this kind of resin has high viscosity, so that its application in the production of fine and dense circuit multilayer boards is limited
In addition, the photoimaging agent prepared only with this type of resin is difficult to release after photocuring, and this also limits its application in the assembly line process; 2) acrylic acid copolymer, due to its high activity, Good toughness and strong adhesion to the substrate have good application prospects in high-resolution imaging inks, but the commonly used acrylic copolymers are acrylate copolymers, which copolymerize several different acrylic monomers by free radicals and Subsequent introduction of photosensitive groups to prepare
However, free radical copolymerization is easily affected by many factors, and there are many side reactions, resulting in high viscosity of the prepolymer, which affects the photocurability and alkali water solubility of the copolymer

Abstract

The invention relates to a method for preparing a polyester-type alkaline-water-soluble photocuring resin. The method comprises the following steps: (1) carrying out reaction on dibasic acid anhydride and dibasic alcohol in the presence of at least one organic solvent to obtain a carboxyl-containing polyester compound; (2) carrying out partial esterification reaction on the obtained carboxy polyester compound and an epoxy-group-containing alkene unsaturated monomer in the presence of a polymerization inhibitor and a catalyst to obtain the polyester-type alkaline-water-soluble photocuring resin, of which the branched chain contains unsaturated double bonds and the main chain contains carboxyl. Besides, the invention also relates to a polyester-type alkaline-water-soluble photocuring resin prepared by the method and a photoinduced imaging agent prepared from the polyester-type alkaline-water-soluble photocuring resin. The method is simple, convenient and controllable. The obtained polyester-type alkaline-water-soluble photocuring resin has excellent photocuring property and alkaline water solubility. The photoinduced imaging agent prepared from the photocuring resin has the advantages of high resolution, high adhesive force and high stripping speed.

Description

technical field [0001] The invention relates to a polyester type alkaline water-soluble photocurable resin, a preparation method thereof and a photoimaging agent prepared therefrom. Background technique [0002] With the development of modern electronic technology, the process requirements for printed circuit boards (PCBs) are becoming more and more stringent. And do not accept the supplementary lines caused by opening gaps, etc. The production of printed circuit boards using a wet etching process must use a photosensitive imaging pattern transfer process, and the necessary material for this process is a photoimaging agent. However, what determines the final performance of the photoimaging agent is the film-forming substance it contains, that is, the alkali water-soluble photocurable resin. [0003] At present, the alkali-water-soluble photocurable resin is mainly composed of the following two types: 1) Alkali-water-soluble (that is, the properties that can be dissolved in...
