  • Soluble imide skeleton resin, soluble imide skeleton resin solution composition, curable resin composition, and cured product thereof
    Patent number: 9139687
    Abstract: An imide skeleton resin represented by the following general formula (1) has a coefficient of linear expansion as low as that of polyimide resin and excellent processability like epoxy resin, and is useful as a resin composition for electrical laminates. Five percent by mole or more of the entirety of the A component is a linking group having an imide skeleton represented by the following general formula (4-1). B denotes a hydrogen atom or a group represented by the following structural formula (5). n denotes an integer in the range of 0 to 200. If both of the B's are hydrogen atoms, then n denotes an integer of 1 or more.
