Abstract
The invention relates to a self-adhesive, heat-sensitive recording material, comprising a carrier substrate, a heat-sensitive, color-forming layer that is applied on one side of the carrier substrate and contains at least a non-phenolic color developer in and at least one color former, a siliconized layer on the upper side of the heat-sensitive, color-forming layer that is applied on the carrier substrate, as well as an adhesive layer on the side of the carrier substrate facing away from the heat-sensitive, color-forming layer.
Claims21
A self-adhesive, heat-sensitive recording material, comprising a carrier substrate, a heat-sensitive colour-forming layer applied to one side of the carrier substrate, said layer comprising at least one non-phenolic colour developer and at least one colour former, a siliconised layer on an upper side of the heat-sensitive colour-forming layer applied on the carrier substrate, and an adhesive layer on a side of the carrier substrate facing away from the heat-sensitive colour-forming layer, characterised in that the siliconised layer rests directly on the heat-sensitive colour-forming layer, that the siliconized layer is majoritively at least one siloxane and that the heat-sensitive colour-forming layer comprises at least one flaky pigment, and wherein the self-adhesive, heat-sensitive recording material is carrier-free and can be rolled up on itself so that the heat-sensitive colour-forming layer onto which the siliconized layer is applied is in direct contact with the adhesive layer.
A self-adhesive, heat-sensitive recording material, comprising
- a paper carrier substrate,
- a heat-sensitive colour-forming layer applied to one side of the paper carrier substrate, said heat-sensitive colour-forming layer comprising at least one non-phenolic colour developer, which is N-(ptoluenesulfonyl)-N′-(3-(p-toluenesulfonyloxy)phenyl)-urea and/or [N-[2-(3-phenylureido)phenyl]benzenesulfonamide, at least one colour former, which is 3-N-n-dibutylamino-6-methyl-7-anilinofluoran, at least one flaky pigment, which is talcum in an amount from about 5 to 60 wt.% in relation to the total solids content of the heat-sensitive colour-forming layer, a binder, and a sensitizer, which is 2-benzyloxynaphthalene,
- a siliconized layer on an upper side of the heat-sensitive colour-forming layer applied on the carrier substrate, wherein the siliconized layer is based on at least one siloxane and contains a photoinitiator, and
- an adhesive layer on a side of the carrier substrate facing away from the heat-sensitive colour-forming layer, characterised in that the siliconized layer rests directly on the heat-sensitive colour-forming layer.
A self-adhesive, heat-sensitive recording material, comprising a carrier substrate, a heat-sensitive colour-forming layer applied to one side of the carrier substrate, said layer comprising at least one non-phenolic colour developer and at least one colour former, a siliconised layer on an upper side of the heat-sensitive colour-forming layer applied on the carrier substrate, and an adhesive layer on a side of the carrier substrate facing away from the heat-sensitive colour-forming layer, characterised in that the siliconised layer rests directly on the heat-sensitive colour-forming layer, and wherein the heat-sensitive colour-forming layer comprises at least one flaky pigment and at least one sensitizer selected from the group of fatty acid amide, ethylene-bis-fatty acid amide, wax, carboxylic acid ester, aromatic ether, aromatic sulfone, aromatic sulfonamide.
A self-adhesive, heat-sensitive recording material, comprising a carrier substrate, a heat-sensitive colour-forming layer applied to one side of the carrier substrate, said layer comprising at least one non-phenolic colour developer and at least one colour former, a siliconised layer on an upper side of the heat-sensitive colour-forming layer applied on the carrier substrate, and an adhesive layer on a side of the carrier substrate facing away from the heat-sensitive colour-forming layer, characterised in that the siliconised layer rests directly on the heat-sensitive colour-forming layer, and wherein the heat-sensitive colour-forming layer comprises at least one flaky pigment and at least one sensitizer which have a melting point between about 90 and about 150 ° C.
