PROBLEM TO BE SOLVED: To provide a positive type photosensitive siloxane resin composition not only excellent in performance such as sensitivity, resolution, adhesive force, transmissivity and thermal discoloration, but also having low moisture absorption coefficient by inhibiting gas emission through excellent heat resistance.SOLUTION: There is provided a positive type photosensitive siloxane resin composition containing a siloxane copolymer obtained by hydrolysis and condensation polymerization of one or more kind of reactive silane represented by the chemical formula 1 and one or ore kind of tetrafunctional reactive silane represented by the chemical formula 2 under a catalyst and having polystyrene conversion weight average molecular weight of 1,000 to 20,000, 1,2-quinonediazide compound and a solvent. (R)Si(R)[Chemical formula 1], Si(R)[Chemical formula 2].SELECTED DRAWING: None |
