Further, in the case of thermal transfer recording, a slippery heat-resistant layer is provided in order for the polyethylene terephthalate film base material to run stably over the thermal head. It is known that adhesive strength and running stability (dropout) can be further improved by using a reactive resin and containing fine particles in the anchor coat layer and the slippery heat-resistant layer.

In particular, when the primary particle size or average particle size of the fine particles is Q, 271 m or less, uniform dispersion of the fine particles into the reactive resin becomes even more difficult. When continuously coated, fine particle unevenness occurs in the coating film.

Dispersion of ultrafine particles of 271 m or less is also possible by using an emulsifier that generates shock waves and reducing the viscosity using a solvent. Furthermore, since it can be highly dispersed, it is easy to obtain a coating composition that can form a uniform thin film. Furthermore, since a solvent is used during emulsification, there is little heat generated during emulsification, and there is little risk that the reaction will proceed even if a reaction initiator is contained.
