Abstract: 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.
