  • Publication number: 20160295991
    Abstract: A nail polish bottle comprises a bottle body, a cap including a disc portion having a center hole and one or more air holes and including a discharge passage and one or more external-air introduction grooves in flow contact with the air holes. A pressure opening and closing valve is mounted to the disc portion such that a skirt portion of the valve may sit below the disc portion and a top of the valve may be above the disc portion. The skirt portion may press against the disc portion to close the air holes. When internal pressure in the bottle body opens the top of the valve, nail polish may flow through the discharge passage if the bottle is upside-down. When the internal pressure is released, the top of the valve may close and the skirt portion may move away from the disc to open the air holes.

  • Publication number: 20090155717
    Abstract: The present invention relates to a photosensitive resin composition for a color filter, which has an excellent stripper-resistance and is developed by an alkali aqueous solution, and a color filter formed of the photosensitive resin composition. The photosensitive resin composition includes: (A) a carboxyl-containing acryl-based binder resin; (B) a double bond-containing acryl carboxylate resin represented by the following Formula 1; (C) an acryl-based photopolymerization monomer; (D) a photopolymerization initiator; (E) a pigment; and (F) a solvent. The photosensitive resin composition has excellent stripper resistance, and thus can be used when a color filter is fabricated on a TFT array substrate in order to ensure a high aperture ratio. In the above formula, R1 is hydrogen or methyl, R2 is hydrogen, hydroxyl, C1 to C10 alkyl, or —CO—R5—COOH wherein R5 is a moiety derived from an acid anhydride, R3 is R6COO— wherein R6 is aryl, R4 is R7COO— wherein R7 is alkyl, 5?m?50, 1?n?20, and 10?o?100.
