20100201925 | FLUORENE-BASED POLYMER CONTAINING URETHANE GROUPS, PREPARATION METHOD THEREOF AND NEGATIVE-TYPE PHOTOSENSITIVE RESIN COMPOSITION COMPRISING THE SAME - Provided is a novel fluorene-based polymer having urethane bonds and a method for preparing the fluorene-based polymer. According to the method, a diol compound is condensed with a diisocyanate instead of an acid dianhydride, and then an acid anhydride is reacted with the reaction mixture to introduce desired acid groups into the final polymer. Further provided is a negative-type photosensitive resin composition comprising of the fluorene-based polymer as a binder resin. The composition exhibits improved chemical resistance, good development margin and high sensitivity due to presence of the acid groups despite the low molecular weight of the fluorene-based polymer. | 08-12-2010 |
20100216073 | PHOTOSENSITIVE RESIN COMPOSITION - Disclosed is a photosensitive resin composition suitable for use in a transflective liquid crystal display (LCD).

20120004341 | ALKALI SOLUBLE RESIN POLYMER AND NEGATIVE-TYPE PHOTOSENSITIVE RESIN COMPOSITION INCLUDING THE SAME - Provided are an alkali soluble binder resin that includes a monomer including an unsaturated double bond, an unsaturated double bond character monomer including a carboxylic acid and an unsaturated double bond character monomer including an allyl group as a repeating unit, in which a molecular weight distribution (Mw/Mn) is in a range of about 2.0 to about 3.5, and a negative-type photosensitive resin composition including the alkali soluble binder resin. Re-solubility, fine-patterned substrate adhesion and dispersion stability may be improved by including the alkali soluble binder resin according to the present invention. | 01-05-2012 |
20130130176 | ALKALI-SOLUBLE RESIN AND NEGATIVE-TYPE PHOTOSENSITIVE RESIN COMPOSITION COMPRISING THE SAME - An alkali-soluble resin is provided. The alkali-soluble resin is prepared using a polyfunctional thiol compound as a chain transfer agent. The alkali-soluble resin has a lower viscosity than a resin having the same molecular weight. Further provided is a negative-type photosensitive resin composition comprising the alkali-soluble resin as a binder resin. The use of the alkali-soluble resin lowers the overall viscosity of the photosensitive resin composition to effectively reduce the height of a stepped portion of a photoresist pattern using a small amount of the photosensitive resin composition. | 05-23-2013 |
