  • Patent number: 11940729
    Abstract: The present invention provides a photosensitive composition which can suppress the generation of a development residue on the surface of an electrode and the corrosion of the electrode to form a black pixel division layer, and also can suppress the generation of off-pixel in an organic EL display device comprising the pixel division layer. Disclosed is a photosensitive composition comprising (a) a pigment, (b) a resin having two or more tertiary amino groups in the molecule, and (c) a photosensitive agent, wherein the component (b) contains a resin having a structure represented by the general formula (1).

  • Patent number: 6817934
    Abstract: An abrasive molding consisting essentially of inorganic particles having an average particle diameter in the range of 0.005 &mgr;m to 0.3 &mgr;m, and having a relative density in the range of 45% to 90%, provided that pores having a diameter of at least 0.5 &mgr;m are excluded from the molding. The abrasive molding is used for polishing a material to be polished by using a polishing liquid, preferably water or an aqueous solution of an alkali metal hydroxide, which does not contain a loose abrasive grain.
