Thermo-sensitive imaging coating liquid and application thereof in thermo-sensitive recording material

The invention belongs to the technical field of thermosensitive recording materials, and particularly relates to thermosensitive imaging coating liquid and application thereof in thermosensitive recording materials. The thermosensitive imaging coating liquid comprises the following components: a dye dispersion liquid and a color developing agent dispersion liquid, the dye dispersion liquid and the color developing agent dispersion liquid both contain an emulsifying dispersant, and the emulsifying dispersant is composed of polyvinyl alcohol and fatty alcohol phosphate; the color developing agent dispersion liquid contains a first color developing agent and a second color developing agent; the first color developing agent is a non-phenol color developing agent, and the melting point of the second color developing agent is higher than that of the first color developing The thermosensitive recording material prepared by adopting the thermosensitive imaging coating liquid has the characteristics of environmental p
