Abstract
A method for forming a color filter comprising the steps of providing a transparent substrate having a frontside and a backside, the frontside having thereon a multicolored pattern comprising areas having colored picture elements and areas that are free of the colored picture elements; forming a light-shielding photosensitive resin layer on the transparent substrate to thereby cover the multicolor pattern; exposing the light-shielding photosensitive resin layer to actinic rays through the backside of the transparent substrate, to thereby harden those portions of the light-shielding photosensitive resin layer which do not overlay the colored picture elements; and developing the light-shielding photosensitive resin layer to form light-shielding picture elements on those areas of the substrate which do not have the colored picture elements, wherein the colored picture elements of the multicolored pattern contain a compound represented by formula (I): ##STR1## and R.sub.l and R.sub.2 are as defined herein.
