    • The present invention discloses a photo-sensitive composition, used as a solder resist or a photosensitive material for insulation layers in the production of printed circuit boards. The photo-sensitive composition comprises a prepolymer containing carboxylic groups and unsaturated vinyl groups; photoinitiator; unsaturated photo-monomer; and the reaction adduct of bismaleimide derivative, barbituric acid derivative and epoxy compounds. The obtained photosensitive composition exhibits high adhesion towards PI substrates, in addition, it can be developed with alkaline water. The photosensitive composition obtained in the invention is very useful in packaging substrates, such as P-BGA, T-BGA and F-CSP due to its high heat resistance and solder resistance.
