Abstract

The invention discloses an ultraviolet curable anti-fingerprint coating composition with printability. The composition comprises the following components in parts by weight: 20-50 parts of acrylate resin, 25-65 parts of monomers, 4-6 parts of light initiator, 100-250 parts of solvent, 0.05-0.5 part of flatting agent and 1-5 parts of anti-fouling resin. Compared with the prior art, the invention provides a coating composition having ink printability and anti-fingerprint effect; the fluorine-modified acrylic resin having a high molecular weight is utilized so that the volume of migration in the coating layer formation process is relatively low, which is beneficial for ink printing; a double bond joins in curing; after curing, the volume of migration of the fluorine-containing resin is low, and the coating layer is stable in performance and low in performance change after long-term use.

Description

technical field [0001] The invention relates to the field of ultraviolet light curing coatings, in particular to an ultraviolet light curing anti-fingerprint coating composition with printability. Background technique [0002] Ultraviolet curing coatings (UV coatings) have the advantages of high efficiency, energy saving, wide applicability, and room temperature curing, and have been widely used in electronics, communications, chemicals, machinery, furniture, inks and other fields. According to the different substrates used, UV coatings can be simply divided into: UV coatings for plastic substrates, UV coatings for metal materials, UV coatings for wood, UV coatings for inorganic materials, UV coatings for paper, etc. [0003] With the rapid development of the electronics and communication industries, the demand for UV coatings on plastic substrates is also increasing, and the great development of touch-based electronic products has put forward new requirements for UV coating...
