<P>PROBLEM TO BE SOLVED: To provide a phosphorus-containing compound capable of securing sufficient flame retardance without using a halogen-based flame retardant, obtaining a sufficient resolution by an alkaline developing liquid, without having the discoloration of surface and blisters at the boundary of copper and a resin on a wiring board in the PCT test, and also sufficiently reducing the problem of bleeding out, a resin composition containing the phosphorus-containing compound, a photosensitive film by using the resin composition, a method for forming a resist pattern and a printed wiring board. <P>SOLUTION: This phosphorus-containing compound containing a vinyl monomer having a phosphorus compound structure in its side chain, a vinyl monomer having a carboxyl group in its side chain and a vinyl monomer having an aryl or ester group in its side chain as structural units, the resin composition containing the compound, the photosensitive film 1 obtained by using the resin composition, the method for forming the resist pattern and the printed wiring board are provide. <P>COPYRIGHT: (C)2009,JPO&INPIT |
