Abstract
The invention discloses a high-transparency low-haze flexible copper-clad plate. The high-transparency low-haze flexible copper-clad plate comprises a PET film, wherein copper foil is arranged on the PET film through a polyester adhesive in a press fit mode. The polyester adhesive comprises, by weight, 75-90 parts of polyester resin, 5-25 parts of end-blocked isocyanate solidifying agent, 0.01-1.0 part of curing accelerator and 0.01-2.0 parts of antioxidant. The light transparency of the flexible copper-clad plate can be improved so that the flexible copper-clad plate can be applied to optical elements, display screens and other high-end elements, and light transparency is high and can reach 85%; haze is low and smaller than 40%; interlayer bonding force is large and can reach 0.8 kgf/cm.
