Abstract: The present invention provides a photosensitive resin composition and a cured film prepared therefrom. The photosensitive resin composition includes a mixture of two or more siloxane polymers having different dissolution rates with respect to an aqueous solution of tetramethylammonium hydroxide. The composition keeps high transparency and high sensitivity, which are advantages of a composition containing a siloxane polymer, and has excellent chemical resistance, thereby providing a cured film having excellent stability in a post-processing.

Abstract: The present invention relates to a photosensitive resin composition that is excellent in adhesiveness and sensitivity. Specifically, the photosensitive resin composition is capable of providing a cured film that is excellent in transparency, sensitivity, chemical resistance, and adhesiveness upon immersion in a stripper. Thus, the cured film can be effectively used in a liquid crystal display, an organic EL display, and the like.

Abstract: The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. The positive-type photosensitive resin composition comprises an acrylic resin and a siloxane copolymer containing a sulfonated diazoquinone group at the terminal thereof. Thus, the film retention rate and adhesiveness can be further enhanced, while the sensitivity is maintained.

Abstract: The present invention relates to a photosensitive resin composition and to a cured film formed therefrom, wherein the photosensitive resin composition can improve the sensitivity by using an alcoholic solvent, along with a siloxane polymer and a quinone diazide compound conventionally used, which enhances the solubility in a developer through an interaction between the alcohol and the diazonaphthoquinone (DNQ) group in the quinone diazide compound, as well as can form a cure film having excellent film retention rate even after post-bake.

Abstract: Disclosed herein are a photosensitive resin composition and a cured film prepared therefrom. The photosensitive resin composition introduces a siloxane polymer containing a fluorine atom which has strong water-repellency into a composition including a common siloxane polymer and an epoxy compound, and fluorine groups may be present in the whole region of the cured film so that the water-repellency due to a fluorine component may be maintained even after removing the surface of the cured film is removed via a dry etching process. As a result, the resistance (chemical resistance) to chemicals used in a post-processing can be maximizes to provide a cured film having excellent stability.

Abstract: The present invention relates to a positive-type photosensitive resin composition and a cured film prepared therefrom. In the composition, the developability (i.e., development rate) is appropriately adjusted by the interaction between the photoactive compound of a polymer, and/or the photoactive compound of a monomer, containing a repeat unit having a specific structure and the two kinds of a binder resin (i.e., a siloxane copolymer and an acrylic copolymer). Thus, it is possible to reduce the rate of loss in the thickness of a cured film during the development step. In addition, the use of the composition allows an increase in the exposed portion (i.e., the portion exposed to light) by the interaction between the two kinds of a binder resin and the photoactive compound, which increases the solubility in a developer, whereby the sensitivity can be enhanced. Further, the composition is capable of forming a cured film that is excellent in film retention rate and has a smooth surface even upon the post-bake.

Abstract: The present invention relates to a photosensitive resin composition and a cured film prepared therefrom. The photosensitive resin composition additionally includes a thermal acid generator in addition to a conventional siloxane polymer, and an 1,2-quinonediazide compound, and a hydrogen bond between the diazonaphthoquinone group (DNQ) of the quinonediazide compound and the siloxane polymer may be cleaved by an acid generated from the thermal acid generator even if a photobleaching process is not performed during the preparation of a cured film. Accordingly, when the photosensitive resin composition is used a cured film having high transmittance and high resolution may be provided efficiently without any restrictions on a process equipment. In addition, the increase of the transmittance of the cured film may be maximized when acid groups generated from the thermal acid generator is a strong acid having a pKa value of ?5 or less.

Abstract: Disclosed herein are a photosensitive resin composition and a cured film prepared therefrom. The photosensitive resin composition includes a siloxane polymer, a 1,2-quinonediazide compound, an epoxy compound and at least one silane compound represented by formula 1. The silane compound together with the epoxy compound in the resin composition further reduces the number of highly reactive silanol group present in the siloxane polymer. As a result, the resistance (chemical resistance) to chemicals used in a post-processing can be maximized to provide a cured film having excellent stability.
