Title:
HEAT TRANSFER SHEET
Document Type and Number:
Japanese Patent JP3440342
Kind Code:
B2
Abstract:
PURPOSE: To prevent the color change of a dye and turn the color reproduction to be of high concentration by containing dyes of given kinds selected by respective given formulas in yellow, magenta and cyanogen dye carrying layers as heat flowing dyes to be contained in a dye carrying layer.
CONSTITUTION: One or two kinds of dyes selected from formula I and formula II by a yellow dye carrying layer as a heat flowing dye contained in a dye carrying layer together with a bonding agent resin are contained. Also dyes in a formula III, a formula IV and a formula V are contained in a magenta dye carrying layer. A dye in a formula VI is contained in a cyanogen carrying layer. A heat transfer sheet 1 is formed by laminating dye carrying layers 12 constituted as above, and a viscosity preventing layer 13 on a substrate 11. A sliding layer 14 is formed on the opposite side of the substrate 11 in the constitution.
