  • Radiation-curable composition for optical fiber matrix material
    Patent number: 6122428
    Abstract: A curable composition is disclosed that is useful for securing color coded optical fibers in a matrix of an optical fiber cable. The matrix material can be stripped from the individual fibers without removing the color coding associated with the individual fibers. The matrix material is also resistant to solvents used in the stripping process.
