Patent ID: 10613435

Abstract:
A coating solution has a polymer having a formula (1) structural unit, a formula (2) primary, secondary, or tertiary amine, and a formula (3) ester capable of dissolving the polymer and amine: R1 is a hydrogen atom or methyl group. L is a divalent aromatic group optionally having at least one substituent, —C(═O)—O— group, or —C(═O)—NH— group. The —C(═O)—O— or —C(═O)—NH— group carbon atom is attached to a polymer main chain. X is a hydrogen atom or linear or branched alkyl or alkoxy group having a 1-10 carbon atom number. At least one alkyl group hydrogen atom is optionally substituted with a halogen atom or hydroxy group. R2, R3, and R4 are independently a hydrogen atom, hydroxy group, or linear, branched, or cyclic organic group having a 1-16 carbon atom number. R5 and R6 are each independently a linear or branched organic group having a 1-16 carbon atom number.
