Dye-containing curable composition, color filter, and producing process thereof

A color filter comprising a dye-containing curable composition containing a binder and a dye that is soluble in an organic solvent, wherein the binder contains a structural unit represented by the following general formula (I) and has a glass transition temperature in a range of 0 to 250° C.,

• wherein R1 represents a hydrogen atom or a methyl group;
• R2 represents an oxygen atom, —NH—, or —N(R3—R4)—;
• R3 represents a substituted or unsubstituted divalent group;
• and R4 represents a group containing an unsaturated double bond.

A process of producing a color filter, the process comprising the steps of:

• applying, on a support, a dye-containing curable composition containing a binder and a dye that is soluble in an organic solvent;
• exposing the dye-containing curable composition to light through a mask;
• and
• forming a pattern by development,
• wherein the binder contains a structural unit represented by the following general formula (I) and has a glass transition temperature in a range of 0 to 250° C.,
• wherein R1 represents a hydrogen atom or a methyl group;
• R2 represents an oxygen atom, —NH—, or —N(R3—R4)—;
• R3 represents a substituted or unsubstituted divalent group;
• and R4 represents a group containing an unsaturated double bond.

• wherein R11 represents a hydrogen atom or a methyl group;
• R12 represents an oxygen atom, —NH—, or —N(R13—R14)—;
• R13 represents a substituted or unsubstituted divalent group;
• R14 represents a group containing an unsaturated double bond;
• and x indicates a molar fraction of a copolymerizing constituent unit and represents a value that satisfies 0≦x≦100.
