Beschreibung
Zusammenfassung:	The present invention provides a titanium black composition, a polyamic acid composition, a polyimide film and laminate thereof. The titanium black composition with great dispersivity is made by covering the titanium black with silane having a specific structure which is epoxy group or aromatic group. The titanium black is added to polyamic acid to obtain the polyamic acid composition. The polyamic acid composition is used to produce polyimide film and laminate thereof with low dielectric loss and black masking performance.
