Definitions
- the present invention relates to a recording material comprising a substrate and a coating comprising at least 3 layers, wherein the outermost layer contains nanoparticles and the inner layers together contain at least one color former, at least one color developer, at least one absorber and at least one solubilizer and color former and color developer not in same location are included.
- the invention further relates to a method for producing the recording material according to the invention and to a laser marking method in which the recording material according to the invention is irradiated with a laser.
- Heat-sensitive recording materials are known in which a color former and a color developer are present side by side in a coating, which are intended to contact each other in the heat, whereby they undergo a color forming reaction and produce color images.
- a recording head for contacting the recording layer of the heat-sensitive material
- a recording head thermal head
- problems such as. For example, wear of the head, adhesion of dust or other particles to the tip of the head, and sticking of the head to the recording layer.
- the method is not suitable for high-speed recording because the recording speed depends on the duration of heat release by the thermal head, and the resolution of the color images is limited due to the heat diffusion. Therefore, instead of the contact method using a thermal head, various non-contact recording methods have been proposed wherein a laser or similar light beam is used for recording.
- IR laser radiation is also after the lesson of EP 0 637 514 A1 used, wherein the coloring coating is additionally added an inorganic substance which is to improve the absorption of the infrared radiation (so-called absorber).
- the recording materials used in the described labeling method have the disadvantage that they are very sensitive to unwanted color reactions. Often, even the finger sweat on touching the recording materials leads to unwanted color reactions. Also, the recording materials are not storage stable.
- the object of the present invention was therefore to provide a recording material in which the disadvantages of the prior art, in particular the already mentioned sensitivity to unwanted color reactions and the lack of storage stability, are overcome.
- the present invention thus provides a recording material comprising a substrate and a coating comprising at least 3 layers, wherein the outermost layer contains nanoparticles and the inner layers together contain at least one color former, at least one color developer, at least one absorber and at least one solubilizer and color formers and color developers are not contained in the same layer, and a method for producing this recording material.
- the subject of the present invention is a laser marking method in which the recording material according to the invention is irradiated with a laser.
- the object of the present invention has, inter alia, the feature that the coloring coating contains at least one substance which absorbs radiation of a specific wavelength and converts it into heat energy (so-called absorber).
- This thermal energy initiates a chemical reaction between a color former and a color developer in the colorant coating of the recording material, which then results in a color reaction.
- an energy absorber in a defined wavelength range (e.g., 800 nm to 2,000 nm)
- other than the commonly used infrared lasers may be used, such as fiber lasers, Nd: YAG lasers, or diode lasers.
- the absorber absorbs electromagnetic radiation in a wavelength range of 800 nm to 2,000 nm.
- An absorbing substance can be any inorganic or organic compound which has an absorption, preferably more than 60 percent of the energy radiated, in the desired wavelength range.
- suitable absorbent substances are the following: mica coated with antimony-doped tin oxide ("Lazerflair”, Merck), copper hydroxyphosphate ("Budit 322", Budenheim), iridium tin oxide ("Adnano ITO", Evonik-Degussa ), phlegmatized aluminum powder (“MaG-6-10", Eckart), perylene derivatives ("Lumogen", BASF), phthalocyanines ("PRO-JET”, Fujifilm).
- combinations of one or more absorbers with one or more solubilizers are possible, which are in the form of a microencapsulated system.
- the use of the absorbing substance may be carried out in any desired amount, but preferably, the absorber is contained therein at 0.1 to 10 parts based on the entire coloring composition.
- the color image systems useful in the present invention are not critical, provided that the present at least one color former and at least one color developer are present in such a combination that they are brought into contact with each other under the action of heat to undergo a color forming reaction.

- the absorbent substance used in the invention When the absorbent substance used in the invention is e.g. is used in a combination of a basic color former and an acidic color developer, among other combinations, this substance exhibits an extremely high efficiency in improving the recording sensitivity.
- the use of the above-mentioned combination of a basic color former and an acidic color developer is therefore particularly preferred.
- Dyes based on diphenylmethane eg. B. 4,4'-Bisdimethylaminobenzhydryl-benzyl ether, N-halophenyl-leucoauramine, N-2,4,5-trichlorophenyl-leucoauramine.
- Dyes based on spiro compounds eg. 3-methyl-spiro-dinaphthopyran, 3-ethyl-spiro-dinaphthopyran, 3-phenyl-spiro-dinaphthopyran, 3-benzyl-spiro-dinaphthopyran, 3-methyl-naphtho (6'-methoxybenzo) spiro-pyran, 3-propyl-spiro-dibenzopyran.
