A 3-arylphenyl sulfide compound represented by general formula (I):

• wherein:
• R is a C2-C6 alkyl group, which may be substituted by one or more halogen atoms or cyano groups;
• a C2-C6 alkenyl group which may be substituted by one or more halogen atoms or cyano groups;
• a C2-C6 alkynyl group which may be substituted by one or more halogen atoms or cyano groups;
• a C3-C6 cycloalkyl group which may be substituted by one or more halogen atoms or cyano groups;
• or a C4-C9 cycloalkylalkyl group which may be substituted by one or more halogen atoms or cyano groups;
• n is an integer of from 0 to 2,
• Ar is a group represented by any one of general formulae:
• wherein
• Q1 is C-A,
• Q2, is C-A2,
• Q3, is C-A3,
• Q4 is C-A4, and
• Q5 is C-A5,;
• wherein A1 and A5 are hydrogen atoms,
• wherein B0 is selected from the group consisting of a hydrogen atom, halogen atom, amino group, cyano group, nitro group, C1-C6 alkyl group, and a C1-C4 haloalkyl group;
• wherein A2, A3, A4, B1, B2 and B3 are selected from the group consisting of a hydrogen atom, halogen atom, cyano group, nitro group, C1-C6 alkyl group which may be substituted by one or more halogen atoms, hydroxyl groups, cyano groups, C2-C7 alkoxycarbonyl groups or C1-C6 alkoxy groups;
• C2-C6 alkenyl group which may be substituted by one or more halogen atoms or cyano groups, C2-C6 alkynyl group which may be substituted by one or more halogen atoms or cyano groups;
