PHOTOSENSITIVE COMPOSITION FOR RED COLOR FILTER AND RED COLOR FILTER FORMED BY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a photosensitive compsn. for red color filters having excellent chromaticity, transmittance and contrast and having excellent light resistance and chemical resistance and the red color filters formed by using the same. SOLUTION: This photosensitive compsn. for the red color filters contains a photopolymerizable compd. having at least one piece of addition polymerizable ethylenic double bonds, a photopolymn. initiator and pigment. The pigments contain the anthraquinone pigment expressed by the formula [where, R1 , R2 , R3 , R4 are the same or different and denote hydrogen atoms or alkyl groups which may have alkyl groups in side chains (where the total sum of the carbon atoms of R1 to R4 is 1 to 8)] and an Fe2 O3 pigment in which the pigment particles having an average grain size of 0.03 to 0.25μm occupies 80 to 100wt.% in a range of the anthraquinone pigment: Fe2 O4 pigment =1:9 to 9:1 (by weight). The red color filters formed by using the same are obtd.
