ALKALI SOLUBLE RESIN POLYMER WITH FLUORENE GROUP, METHOD OF MANUFACTURING THE POLYMER AND NEGATIVE PHOTOSENSITIVE RESIN COMPOSITION INCLUDING THE POLYMER

摘要

PURPOSE: An alkali soluble resin polymer, a producing method thereof, and a negative photosensitive resin composition including thereof are provided to secure a proper molecular weight and acid value by reacting a compound including a fluorene group with an acrylic binder resin. CONSTITUTION: An alkali soluble binder resin polymer contains fluoren. The fluoren is obtained by reacting a fluoren compound by a reaction of a compound marked as chemical formula 1 with acrylic acid or methacrylic acid, with an alkali soluble binder resin. In the chemical formula 1, X refers to alkylene with the carbon number 1~3, ethylene oxide, and propylene oxide.
