| 摘要 |
Disclosed is a curable resin composition that contains a resin containing carboxyl groups, titanium oxide, and a metal phosphinate, and preferably contains a thermosetting resin, so as to be able to achieve halogen-free flame resistance and make possible formation of a highly reflective white coating layer with superior resolution and low warpage. A carboxylic acid resin having a urethane skeleton is preferable for the resin containing carboxyl groups. Also disclosed is a printed wiring board formed by using this curable resin composition or a dry film thereof and on which a flame resistant film, such as a solder resist, is formed thereby. |
