Abstract

Belonging to the technical field of quantum dots, the invention in particular relates to a coated paper and a preparation method thereof. The coated paper includes raw paper, at least one side of theraw paper has a coating layer, which is mainly composed of a pigment, quantum dots, a coupling agent and an adhesive. The coated paper has good printability, ink permeability, ink absorption, surfacesmoothness, water resistance, and the anti-counterfeiting performance of easy discrimination and difficult imitation.

Description

technical field [0001] The invention belongs to the technical field of quantum dots, and particularly relates to a coated paper and a preparation method thereof. Background technique [0002] Coated paper is a paper coated with a layer of paint on the base paper to make it have good optical properties, printing performance and some special properties; it is mainly composed of coated base paper, pigment fillers, adhesives and other agents or coatings Auxiliary composition, with the continuous development of market demand and printing technology, the use of coated paper is increasing, and the development prospect is broad. The commonly used anti-counterfeiting technologies for existing coated paper mainly include watermark, security thread and anti-counterfeiting fiber; watermark anti-counterfeiting technology is easy to be imitated due to its early appearance; security thread anti-counterfeiting requires special equipment, complex production process and high cost; common anti...
