Heat transfer sheet for color image formation

A heat transfer sheet for color image formation comprising respective dye carrying layers containing dyes with respective hues of cyan, magenta and yellow formed on a substrate sheet, wherein the inorganic/organic value (I/O value) of the dye is 2.30 or less, the dyes contained in the dye carrying layers have molecular weights of 280 or more and wherein said respective dye carrying layers each contain one kind or plural kinds of dyes, and the color characteristics of said respective dye carrying layers satisfy the following conditions as the color characteristics (based on GATF) in a state of having been transferred on an image receiving sheet:

• cyan:
• hue error is in the range of from 10% on the green side to 60% on the blue side, and turbidity is 35% or less in the range of hue error from 10% on the green side to 45% on the blue side and is 20% or less in the range of hue error from 45% to 60% on the blue side;
• magenta:
• hue error is in the range of from 10% on the blue side to 60% on the red side, and turbidity is 25% or less in the range of hue error from 10% on the blue side to 35% on the red side and is 10% or less in the range of hue error from 35% to 60% on the red side;
• yellow:
• hue error is in the range of from 10% on the red side to 10% on the green side, and turbidity in this range is 10% or less.
