Abstract

The subject compositions contain a) ketoxime-ester selected from the compounds shown in formula (I), in particular 1-[9-Ethyl-6-(2-methyl-benzoyl)-9.H.-carbazol-3-yl]-ethanone-O-acetyl-oxime; b) one or more radically polymerizable ethylenically unsaturated compound(s), c) colorant(s), and d) a binder resin. Said compositions are used in the manufacturing of color filters (CF). The compositions comprising 1-[9-Ethyl-6-(2-methyl-benzoyl)-9.H.-carbazol-3-yl]-ethanone-O-acetyl-oxime and similar ketoxime esters can be employed for producing the red, green and blue colored coatings and a black matrix of a CF to be used to manufacture flat panel displays such as liquid crystal display, plasma display panel and electroluminescence display, and image sensors such as CCD (Charge Coupled Device) and CMOS (Complementary Metal Oxide Semiconductor) sensors for scanner, digital camera and video camera.
