Abstract
The copolymer has an acid group-bearing structural unit (a) and a structural unit (b) that has a group represented by formula (1-1) (In formula (1-1), R1 is a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms; R2 and R3 are each independently a hydrogen atom or a hydrocarbon group having 1-20 carbon atoms; and * represents a linking site that links to a residue provided by the removal of the group with formula (1-1) from the structural unit (b).).
Claims17
A photosensitive coloring composition comprising:
- a copolymer (A) comprising
- a structural unit (a) having an acid group;
- and
- a structural unit (b) having a group represented by the following formula (1-1) or the following formula (1-2):
- wherein, in formula (1-1), R1 is a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, R2 and R3 are each independently a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, and * represents a linking site with a residue obtained by removing the group of formula (1-1) from the structural unit (b);
- wherein, in formula (1-2), R2 and R3 are each independently a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, R4 is a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms, and * represents a linking site with a residue obtained by removing the group of formula (1-2) from the structural unit (b);
- a reactive diluent (B);
- a photopolymerization initiator (C);
- a solvent (D);
- and
- a coloring agent (E).
