Figure BDA0002213623780000041
Physical Property test
The multifunctional composition was coated on the corona side of PET using the comma blade process, pre-baked at 40-100 ℃ for 3 minutes, and then applied at 300mj/cm2~1000mj/cm2The UV energy is used for curing, so that no bubbles and no obvious impurity points exist in the appearance, and the multifunctional film is obtained.
