Patent ID: 8916621

Claim:
A method for producing a color filter comprising: I) applying a radically polymerizable composition on a support, wherein the radically polymerizable composition comprises: (a) at least one alkaline developable resin; (b) at least one acrylate monomer; (c) at least one photoinitiator; and (d) at least one hydroxylamine ester compound of formula I wherein R a represents an acyl radical; one of R b and R c represents hydrogen and the other one represents a substituent; or R b and R c both represent hydrogen or identical or different substituents; or R b and R c together represent oxygen; or R b and R c together form a ring; R 1 -R 4 each represent C 1 -C 6 alkyl; and R 5 and R 6 each represent independently of one another hydrogen, C 1 -C 6 alkyl or C 6 -C 10 aryl; or R 5 and R 6 together represent oxygen; II) drying the photopolymerizable composition; III) exposing the photopolymerizable composition to UV light through a mask; IV) developing the exposed composition layer with an alkali developer to form a colored pattern; and V) post baking the exposed photoresist at 180 to 230° C.
