| abstract |
The present invention relates to a positive photosensitive silicone resin composition comprising hydrolyzing and polycondensing i) reactive silane represented by the following chemical formula 1 and ii) tetrachlorosilane under catalytic conditions, and removing unreacted monomers and catalysts The obtained polystyrene conversion weight average molecular weight is a siloxane-based copolymer of 1,000 to 20,000. The positive photosensitive siloxane resin composition of the present invention not only has excellent sensitivity, resolution, adhesion, transmittance and thermal discoloration resistance, but also can realize low emission due to its excellent heat resistance. gas, and maintain a low moisture absorption rate, which can ensure excellent panel reliability. |
