Abstract:
    The present invention relates to a photosensitive composition suitable for forming black matrix screens and fluorescent screens of color cathode-ray tubes and having such a high photosensitivity as to enable a remarkable shortening of the exposure time and a high stability even after the lapse of time. The composition comprises 70 to 99 % by weight of a vinylic polymer (A) having repeating units derived from a monomer (a) which is represented by the general formula (1): H2C=CH-X-Q and wherein the functional group Q has a frontier-electron density as defined by the following equation of at least 0.067 and 30-1 % by weight of a photosensitive compound (B) comprising azide and/or diazo compounds: frontier-electron density = 2 * (coefficient of atomic orbital of lowest vacant orbital)
