Description Soluble and inherent photoimageable polyimides with improved photo-patterning features were prepared from α,α-bis (4-amino-3,5-dimethylphenyl)phenylmethane (BADP) and 3,3',4,4'-benzophenonetetracarboxylic dianhydride (BTDA). The polyimides possess good combined chemical and physical properties, of which thermal stability with initial thermal decomposition temperature of 525℃ and high glass transition temperature of 318℃ were observed. Homogenuous polyimide solution in common organic solvents with as high as 20 wt % of solid content could be prepared, which is stable for storing of >3 months. The polyimide has high electric insulating properties and low dielectric constant and dissipation factor. Fine patterns could be processed by directly exposing the polyimide coating upon UV i-line, followed by developing with an organic developer.
