    摘要： The present invention aims to provide a coating liquid for producing an optical recording medium that can record large volumes of data and can respond sufficiently to high speed writing, a method for producing an optical recording medium using the same, and an optical recording medium. The coating liquid for use in a method for producing an optical recording medium according one embodiment of the invention contains a solvent and a pigment dissolved in the solvent. The solvent includes TFP and/or OFP and an aliphatic saturated alcohol having 1-4 carbon atoms by 0.01-10% by mass relative to the total amount of the solvent, and the pigment includes the compound represented by the following general formula (1) and a chelate compound consisting of an azo compound and a metal. [where, each of R11, R12, R13 and R14 (hereinafter, represented as “R11-R14”) represents independently from one another a benzyl group that may have a substituent or an alkyl group having 1-4 carbon atoms, R15 represents a trimethine chain that may have a substituent, each of R16 and R17 represents independently from each other a group of atoms that constitute a benzene ring that may have a substituent or a naphthalene ring that may have a substituent, and each of R18 and R19 represents independently from each other an aryl group that may have a substituent or an alkyl group having 1-4 carbon atoms, provided that at least one group among R11, R12, R13 and R14 is not a methyl group. In this case, respective carbons of R11 and R12 and/or R13 and R14 may make a bond to form a 3- to 6-membered ring.]
