PURPOSE:To continuously control the density of transfer recording dots by a method in which in the case of temperature-rise writing control, the bonding and transference of a tacky material in the non-temperature rise writing section of the recording material to a recording medium is interrupted. CONSTITUTION:A porous layer 122b of non-adhesive solid resin material is formed on the surface of a tacky material 122a containing any colorant of dyes and pigments, and thereby the bonding and transference of the tacky material 122a in the non-temperature rise section during the temperature rise writing control period to the recording medium is interrupted to improve the quality of tacky transferred recording pictures by fogging transfer. To prevent the dissolution of the tacky material layer 122a and also of dyes present in the solvent used during the formation of the layer 122b, solvents for the resin material should be properly selected or the use of aqueous emulsions is recommended. The fogging transfer of the material 122a can thus be prevented by the layer 122b, and when a temperature-rise writing is made on the recording material, tacky transfer recording density is analog-tonally controlled to obtain a multi- tonal picture. |
