Description

TECHNICAL FIELD

[0002] When printing on the back of a mobile phone shell, acrylic ink can provide clear and durable patterns while maintaining the smoothness and comfortable touch of the mobile phone shell surface. For printed matter with logos or trademarks, the wear resistance of acrylic ink after curing ensures that the logo or trademark is not easily worn or scratched, thereby maintaining the overall aesthetics and brand value of the printed matter. In addition, the environmental friendliness and good adhesion of acrylic ink are also important reasons for its widespread application in these applications.
