<p>A silicon-modified adhesive polyimide film comprises 60 mole % or more of repeating units of the formula: <CHEM> in which: L<1> represents -O-, -CO-, -SO<6>-, -S- or C (R4)<6> (in which R4 represents -CH<7>, -CF<7> or H); R<3> represents a group of the formulae: <CHEM> <CHEM> -(CH<6>)s- (IV) or <CHEM> (in which s represents an integer of 1 to 4); the group (SILO) is a group of the formula: -Si äR5(3-m)ü äO(m-1)/2ü -O-Si äR5(3-m)ü äO(m-1)/2ü- (VI) (in which R5 represents a C<5>-C1/4 alkyl group, a phenyl group, or a C<5>-C<5><6> alkyl-substituted phenyl group and m is the range of 1<m&3); the group (PI) is a group of the formulae; <CHEM> Äin which L<1> has the meaning defined above, L<2> represents -O-, -CO-, -SO<6>-, -S-, or -C(R4)<6> - (wherein R4 represents -CH<7>-, -CF<7> or H), R<1> represents a C<5>-C1/4 alkyl group, a phenyl group or a C1/2 -C<5><6> alkyl-substituted phenyl group, R<2> represents a group of the formula (II) to (V) defined above, P is in the rang eof 1& P &100, n is in the range 1& n <3, and p and q are each in the range defined by the formulae (VIII) and (IX): <MATH> <MATH></p> |
