Abstract
A thermal transfer ribbon comprising a dye layer and a transferable protective layer repeatedly formed on one surface of a substrate, the transferable protective layer having a first layer formed on the substrate, and a second layer formed on the first layer. The first layer comprises an acrylic resin (X) containing methyl methacrylate, an acrylic resin (Y) containing a styrene resin, and a polyester resin (Z). X has a weight average molecular weight of 120000 or more, the mass ratio of X and Y is within the range of 1:9 to 9:1, and the mass of Z is 1% or more and 3% or less of the total mass of X and Y.
