SUBLIMATION TRANSFER TYPE HEAT SENSITIVE RECORDING CYANOGEN COLORING MATTER SUBLIMATION TRANSFER TYPE HEAT SENSITIVE RECORDING INK COMPOSITION AND SUBLIMATION TRANSFER TYPE HEAT SENSITIVE RECORDING HEAT TRANSFER SHEET

摘要

PURPOSE: To provide a sublimation transfer type heat sensitive recording heat transfer sheet having good transfer properties to an image receiver, by a method wherein a carrying layer which is obtained by dispersing or melting a specific cyan coloring matter into a resin binder is provided on the whole surface of a base sheet. ;CONSTITUTION: A cyan coloring matter represented by formula I [A₁-A₄ dinote H, an alkyl group and alkoxy group, X₁ dinotes formula II (R₁ dinotes an alkyl group or alkenyl group), R₂ dinotes a methylene group or a hydroxy group, X₂ dinotes O, S, SO, T and u dinotes H or C_1-4 alkyl group, n dinotes an integral number of 1-3, Q dinotes five-membered or six-membered or seven-membered heterocyclic residues and Y denotes H or C_1-4 alkyl group] is mixed up with a resin binder such as ethyl hydroxyethyl cellulose and a solvent and dispersed into those, through which an ink composition is prepared. This ink composition is applied onto a substrate such as synthetic paper or plastic film, dried and a coloring matter carrying layer is formed, through which a sublimation transfer type heat sensitive recording heat transfer sheet is made.;COPYRIGHT: (C)1994,JPO&Japio
