ABSTRACT:
A silicon-modified, adhesive polyimide film composed mainly of the repetition units of the formula (I) and a process for producing a polyimide film composite product using the above film are provided, the formula (I) being ##STR1## the above process for producing a polyimide film composite product comprising subjecting the above-silicon-modified polyimide film to contact-bonding on heating to a material to be adhered, at an ultimate curing temperature of 130.degree.-230.degree. C.
The above polyimide film is highly adhesive and heat-resistant in spite of heating at a relatively low temperature.
