摘要：
An electrophoretic positive working photosensitive composition for producing a photoresist pattern on metal base plate comprises a photosensitive compound, in which a photosensitive quinone diazide group is grafted on a polyester, and an acrylic copolymer containing carboxyl group, the composition forms a smooth photoresist film on the plate and has a good adhesion to the surface that no pinehole is found.
