    摘要： An ink-jet recording sheet is provided with at least one ink-receiving layer on at least one side of a base material sheet. A resin component which constitutes the ink-receiving layer comprises a hydrophilic polyurethane resin, hydrophilic polyurea resin, hydrophilic polyurethane-polyurea resin or hydrophilic polyamide resin having siloxane segments in a molecule thereof. As an alternative, the ink-receiving layer comprises a porous hydrophilic polyurethane resin, a porous hydrophilic polyurea resin or a porous hydrophilic polyurethane-polyurea resin.

    摘要： A thermal ink ribbon has a base sheet, a thermal recording layer arranged on one side of the base sheet, and a back layer arranged on an opposite side of the base sheet. The back layer according to the present invention comprises a polyurethane resin which is obtained by reacting a low molecular weight polymer having at least one active-hydrogen-containing group at one end of the molecule, a compound having at least one active-hydrogen group and at least one hydrophilic group except a hydroxide group, with a polyisocyanate. The back layer is excellent in the adhesiveness to a base sheet, the heat resistance relative to a thermal head and slipperiness to a thermal head; and the ink ribbon with such a back layer has no problems in printed characters and figures on printing, in the migration of impurities from the back layer into an ink layer, in smeariness of a thermal head and in its maintenance. Such a back layer is capable of being formed on a surface of a base sheet by only applying the coating, which comprises the above polyurethane resin, for forming a back layer; and drying the coated layer.

    摘要： A thermal recording media has a base sheet, a thermal recording layer arranged on one side of the base sheet, and a back layer arranged on an opposite side of the base sheet. The back layer comprises a polyurethane having side chains derived from a fluorine-containing diol represented by the following formula (I): wherein Rf represents a perfluoroalkyl or perfluoroalkenyl group having 1 to 20 carbon atoms; X represents a substituted or unsubstituted alkylene group having 1 to 10 carbon atoms, a substituted or unsubstituted alkenylene group represented by —CH═CH—(CH2)n— in which n stands for an integer of from 1 to 10, or in which n stands for an integer of from 0 to 6; Y represents a direct bond, —O—, —NH—, or —R0—NH— in which R0 is an alkylene group having 1 to 6 carbon atoms; Z represents a direct bond or —N(R′)R— in which R is an alkylene group having 1 to 20 carbon atoms and R′ is a hydrogen atom or an alkyl group having 1 to 6 carbon atoms; R1 and R2 each independently represent a divalent organic group; and R3 represents a residual group of an aliphatic, alicyclic or aromatic diisocyanate.
