Document Type and Number:
WIPO Patent Application WO/2020/024763
Kind Code:
A1
Abstract:
Provided are a photocurable hydrophilic polymer, a coating composition based thereon, a hydrophilic lubricant coating, and a product. The photocurable hydrophilic polymer is formed by the copolymerization of a polymerizable photosensitive monomer having a specific structure and a hydrophilic monomer. The photocurable hydrophilic polymer has high photocuring efficiency, and the preparation method thereof is simple with high production efficiency and less environmental pollution. Further, there is basically no problem of gelation. By curing the coating composition, a hydrophilic coating having high firmness and lubricity and excellent biosafety and compatibility can be obtained.
