Patent ID: 8642181

Claim:
A metal-clad white laminate, comprising: a white resin layer composed of a resin composition which is obtained by mixing a polyimide having a repeating unit as represented by the general formula I with a white pigment: wherein R represents a tetravalent aliphatic group which is derived from cyclohexane; Φ represents a structural unit represented by at least one selected from the group consisting of: and Φ may have a main chain wherein at least one partial structure selected from the group consisting of —O—, —SO 2 —, —CO—, —CH 2 —, —C(CH 3 ) 2 —, —C 2 H 4 O—, and —S— intervenes therein; and at least one metal layer, the white resin layer being an adhesive layer for the metal layer, wherein the at least one metal layer has a thickness of 2 to 100 μm, and the white pigment has a content of 10 to 70% by weight in the resin composition, wherein the white pigment comprises rutile titanium oxide having a surface on which a coating layer is formed, wherein the coating layer on the titanium oxide is obtained by being subjected to SiO 2 or Al 2 O 3 treatment, and wherein the white pigment is particulate and has a particle diameter in a range of 0.05 to 0.43 μm.
