Patent ID: 8546061

Claim:
A photo-curing polysiloxane composition, comprising: a polysiloxane; an o-naphthoquinonediazidesulfonate compound; and a solvent; wherein said polysiloxane contains 25 wt % to 60 wt % of a polysiloxane fraction having a molecular weight ranging from 10,000 to 80,000 based on a total weight of said polysiloxane when calculated from an integral molecular weight distribution curve obtained by plotting cumulative weight percentage versus molecular weight falling within a range between 400 and 100,000 measured by gel permeation chromatography, and wherein the amount of oligomers in the polysiloxane having a molecular weight less than 800 is from 0 wt % to 10 wt % based on a total weight of said photo-curing polysiloxane composition.
