Photoresist dichromate composition containing gelatin coated particles

摘要

A negative-working photoresist composition comprising, in admixture, (a) dye-loaded or dye-precursor-loaded polymeric particles individually covered with a layer of gelatin that is covalently bonded thereto and (b) a radiation-sensitive dichromate is useful in the preparation of continuous tone dyed imaging elements such as color filter arrays for use in solid state color image sensing devices.
