Thermal transfer ribbons that contain mixtures of carbon black and/or other non-melting solids within the thermal transfer layer provide high density images and reduced melt viscosities for the thermal transfer layer where the mixtures contain at least three different sized particles or mixtures of particles and each of the different sized particles comprise 20 to less than 80 volume % of the total volume of the overall particle mixture. Each of the different sized particles also have particle size values which differ from each by a factor of at least 1.5.
