Abstract:
PCT No. PCT/EP97/00268 Sec. 371 Date Feb. 9, 1998 Sec. 102(e) Date Feb. 9, 1998 PCT Filed Jan. 21, 1997 PCT Pub. No. WO97/27608 PCT Pub. Date Jul. 31, 1997The invention relates to a black matrix in color picture tubes, a positive photoresist composition, an agent for protecting a black matrix, and a process for producing said black matrix. The invention is based on the object of providing a black matrix produced using a positive photoresist composition which permits good capability of structuring between exposed and non-exposed areas, and reducing the process for producing the black matrix to a few technological steps. Said object is achieved by means of a black matrix consisting of a light-absorbing matrix, which may be produced from a positive photoresist composition consisting of a suspension including one or more compounds which indirectly or directly release gaseous compounds on exposure to light, a black pigment and suspension-stabilizing and wetting-promoting and/or adhesion-promoting additives; and an agent for protecting the light-absorbing matrix, which may be produced from a negative photoresist composition consisting of a water-soluble organic polymer, a crosslinking actinic component, an alkyl silicate and water, said agent having a pH value of between 6 and 7.5.
