  • Publication number: 20200199261
    Abstract: Provided is an oxime ester phenylcarbazole compound useful as a photoinitiator for photocrosslinking. Specifically, the carbon atom forming a double bond with the nitrogen atom in the oxime ester moiety of the oxime ester phenylcarbazole compound is bonded to the phenylcarbazole group and is directly bonded to a (C1-C20)alkyl or (C6-C20)aryl group. Also provided is a photopolymerizable composition including the oxime ester phenylcarbazole compound. The oxime ester phenylcarbazole compound and the photopolymerizable composition have improved solubilities, are highly photosensitive, and exhibit excellent physical properties in terms of residual film ratio, pattern stability, resist adhesiveness. Due to these advantages, the oxime ester phenylcarbazole compound and the photopolymerizable composition are suitable for use in black resists, color resists, overcoats, column spacers, and organic insulating films of LCDs.

  • Patent number: 10670188
    Abstract: A system for filling an LPG vehicle with LPG using an auxiliary bombe is provided. The system may be configured for easily filling a main bombe with LPG even in the hot season (summertime) or the like during which the outside temperature rapidly rises, by using an auxiliary bombe in addition to using the main bombe. The system may also be capable of always smoothly refilling the main bombe with LPG by moving a portion of the LPG in the main bombe to the auxiliary bombe, when the pressure in the main bombe is higher than the LPG filling pressure of a filling gun in the hot season during which the outside temperature rapidly rises, so that the pressure in the main bombe becomes lower than the filling pressure.
