Abstract
Official abstract text for this publication.
The present disclosure is directed to methods of reducing the amount of colorant in a multilayer film and achieving an L* color less than 30 and a 60 degree gloss value less than 10. The multilayer film has a first polyimide layer and a second polyimide layer containing a matting agent, submicron carbon black and submicron fumed metal oxide.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method of reducing the amount of colorant in a multilayer film and achieving an L* color less than 30 and a 60 degree gloss value less than 10, the method comprising: a) providing a first polyimide layer; b) providing a polyamic acid solution containing polyamic acid, silica matting agent, and submicron carbon black for forming a second polyimide layer; c) adding at least one submicron fumed metal oxide to the polyamic acid solution; d) coating th…
