摘要： The invention relates to a color developer of formula (I), (Ar1—SO2—NH-)m-Y—(—NH—C(O)—NH—SO2—Ar2)n (I), wherein Ar1 is an unsubstituted or substituted aromatic moiety, Ar2 is an unsubstituted or substituted phenyl moiety, Y is at least an (m+n)-times substituted benzene group or naphthalene group, and Y is substituted in such a way that at least one Ar2—SO2—NH—C(O)—NH group is in ortho-position with respect to at least one Ar1—SO2—NH group. The invention further relates to a heat-sensitive recording material, comprising a carrier substrate and a heat-sensitive color-forming layer, which contains at least one color former and at least one phenol-free color developer, the at least one color developer being the compound of formula (I). The invention further relates to a method for producing said heat-sensitive recording material.
