Abstract:
1. A developing solution comprising at least one of compounds represented by the following formulae (I), (III) and (VI) and having a pH of from 2 to 10: wherein R11 represents H, an alkyl group or an alkyl group having a linking group; the linking group includes an ester, carbonyl or amide bond, and the number of carbon atoms connected to N through the bond is from 8 to 20; R12, R18, R28 and R29 each represents H or an alkyl group; R13 represents an alkyl group or a group containing an ethylene oxide group; R30 represents an alkyl group or a group containing an ethylene oxide group; and R14, R19, R20, and R31 each represents an alkylene group or a single bond); provided that, when R11 to R14 have a total of 10 to 40 carbon atoms and when each of R11 to R13 is an alkyl group, or R14 is an alkylene group, the structure thereof is linear or branched; when R18 to R20 have a total of 10 to 30 carbon atoms and when each of R18 and R19 is an alkyl group, or R20 is an alkylene group, the structure thereof is linear or branched; and when R28 to R30 have a total of 8 to 30 carbon atoms and when each of R28 to R30 is an alkyl group, the structure thereof is linear or branched, wherein in formula (III), X wherein a total concentration of the at least one of compounds represented by formulae (I), (III) and (VI) is 2 mass % or more; and wherein the developing solution further comprises a water-soluble polymer compound.
