发明名称 THREE-LAYER FILM, METHOD FOR PRODUCING THREE-LAYER FILM, LAMINATED PLATE AND PRINTED CIRCUIT BOARD
摘要 The present invention relates to a three-layered film, a method for producing a three-layered film, a lamination plate, and a printed circuit board. The three-layered film includes: a polyimide resin film; and a liquid crystal polymer layer having, as a mesogen group, hydroxycarboxylic acid laminated on both sides of the polyimide resin film The thickness of the polyimide resin film (T1) and the thickness of the liquid crystal polymer layer having hydroxycarboxylic acid as the mesogen group (T2) satisfy the relation (a) and (b), wherein the relation (a) is represented by 20 &mu;m <= T1 <= 50 &mu;m, and the relation (b) is represented by 0.3 <= T2/T1 <= 1.5. (The two T2s are reciprocally independent, and can be identical or not.)
