PHOTO-SENSITIVE RESIN COMPOSITION AND A LIGHT SHIELDING LAYER USING THE SAME CAPABLE OF IMPROVING HEAT RESISTANCE CHARACTERISTIC, SHRINKAGE RESISTANCE CHARACTERISTIC, AND TAPER CHARACTERISTIC BY INCLUDING CARDO-BASED RESIN

摘要

PURPOSE: A photo-sensitive resin composition and a light shielding layer using the same are provided to improve sensitivity, developing characteristic, and adhesion.;CONSTITUTION: A photo-sensitive resin composition includes cardo-based resin with repeating units, reactive unsaturated compounds, pigments, initiators, and solvents. One repeating unit of the cardo-based resin is represented by chemical formula 1, and another repeating unit of the cardo-based resin is chemical formula 2. In chemical formulas 1 and 2, R3, R4, R13, and R14 are identical or different and are hydrogen elements, halogen elements, or substituted or non-substituted C1 to C20 alkyl groups; R1 and R2 are identical or different and are hydrogen element or substituted or non-substituted (meta)acrylate; R11 and R12 are substituted or non-substituted (meta)acrylate; R5 is ethylenically substituted group with double bonds; Z1 and Z11 is identical or different and is single bond, O, CO, SO2, CR6R7, SiR8R9, or one of coupling groups. R6 to R9 are identical or different and are hydrogen elements or substituted or non-substituted C1 to C20 alkyl group; Z2 and Z12 are identical or different and are acid anhydride group or acid dihydride group; m1, m2, m11, m12 are the integer of 0 to 4; and n1 and n11 are 1 to 30.;COPYRIGHT KIPO 2012
