- a polyvalent metal salt of an alkyl phosphate ester can be obtained by substituting an alkali metal salt of an alkyl phosphate ester with a polyvalent metal. As such, it is known as a plastic additive, and various grades are available.
- polyvalent metal salt of an alkyl phosphate is represented by the following structural formula 1:
- R in the above formula is an alkyl group having 12 or more carbon atoms.
- the force is also preferably a C12-C18 alkyl group, specifically, for example, a cetyl group, a lauryl group and a stearyl group, particularly preferably a stearyl group.
- M represents an alkaline earth metal, preferably barium, calcium and magnesium, zinc or aluminum.
- n represents the valence of M.
- the metal salt of the alkyl carboxylic acid is represented by the following structural formula 2:
- R 2 C— 0— n 2 M 2
- R is an alkyl group having 11 or more carbon atoms, which is preferable from the viewpoint of slip property during printing.
- a C11 to C18 alkyl group specifically, a dodecinole group, a hexadecyl group, a heptadecyl group, an octadecyl group, more preferably a dodecinole group, a heptadecyl group, an octadecyl group, particularly preferably an octadecyl group (stearyl group) It is.
- M is an alkaline earth metal
- n represents the valence of M.
- M select the metal type according to the temperature conditions used during thermal transfer.
- the melting points are as follows: barium type 190 ° C or higher, calcium type 140 ⁇ 180 ° C, magnesium type 110 ⁇ : about 140 ° C, zinc type 110 ⁇ : about 140 ° C, aluminum type 110-: about 170 ° C, lithium-based 200 ° C or more.

- a mixture in a ratio of 8 to 8: 2. If the amount of the metal salt of alkyl carboxylic acid is too large, scum easily adheres to the thermal head, while if too small, the metal salt is added. The effect is lost.
- a mixture of the polyvalent metal salt of an alkyl phosphate (C) and the metal salt of an alkyl carboxylic acid (D) is used in an amount of:! To 100 parts by mass, preferably 5 to 30 parts by mass per 100 parts by mass of the binder. It is desirable to use in the ratio of. If the amount of the mixture used is too small, sufficient releasability of the thermal head when heat is applied cannot be obtained, and scum tends to adhere to the thermal head. On the other hand, if the amount is too large, the physical strength of the back layer is undesirably reduced.
- the silicone oil contained in the back layer is intended to have a role as a lubricant. Yes, modified silicone oil, unmodified silicone oil and mixtures thereof, with viscosity
- modified silicone oil epoxy, carbinol, phenol, methacrylic or polyether modified silicone oil can be used, and as the unmodified silicone oil, dimethyl silicone oil, methylphenyl silicone oil, and a mixture thereof can be preferably used.
- the releasability is improved, and a higher printing stain prevention effect can be obtained.
- the use of a mixture of silicone oils having different viscosities is more effective in improving the releasability.
- two or more types of silicone oils are mixed, it is effective to use a combination of a modified silicone oil and an unmodified silicone oil, which is effective in improving heat resistance, sealing, and releasability.
- the silicone oil is contained in an amount of 1 to 30 parts by mass, preferably 1 to 10 parts by mass, based on 100 parts by mass of the binder. If the amount is too large, there is a problem that the surface is transferred to the opposite side when wound on a thermal transfer sheet, and there is a problem that a scum adheres to the thermal head at the time of printing, causing a decrease in density and a scumming. The releasability cannot be obtained, and the effect of preventing printing stain cannot be obtained.
- the inorganic filler contained in the back layer is an inorganic fine particle having a Mohs hardness of preferably 3 or less. If the Mohs hardness exceeds 3, wear of the thermal head tends to progress, and the coefficient of friction with the thermal head increases.In particular, the difference in the coefficient of friction between non-printing and printing increases, resulting in a large print sheet. It is easy to occur. Further, when the filler is detached from the back layer, the printing scratches generated on the printing screen become remarkable, which is not preferable.
- inorganic fillers used in the present invention are known per se, for example, talc, kaolin, My power, sekibota, saltpeter, gypsum, bruceite, graphite, calcium carbonate, molybdenum disulfide and the like.
- Talc, my power and calcium carbonate are particularly preferred from the balance of heat resistance and lubricity.
- Mohs hardness is measured with a Mohs hardness tester.
- the Mohs hardness tester was developed by F. Mohs, and contains 10 types of minerals ranging from soft to hard minerals in a box. It is shown. The standard minerals are as follows (numbers indicate hardness). 1: Katsuite, 2: Sekko, 3: Horkai stone, 4: Fluorite, 5: Linkee stone, 6: Ceviche stone, 7: Sekiei, 8: Topaz, 9: Corundum, 10: Diamond
- the hardness is compared based on the force resisting it (whether it is scratched or not). be able to. For example, when the coralstone is scratched, the hardness of the sample is greater than 3 degrees. If the fluorspar is scratched and the fluorspar is not, the hardness of the sample is less than 4 degrees. At this time, the hardness of the sample is indicated as 3-4 or 3.5. If the specimens are slightly scratched, the hardness of the sample shows the same order of hardness as the standard mineral used. The hardness of Mohs' hardness tester is the order of magnitude, not the absolute value.
- the filler When the filler is added at a ratio of 2 to 20 parts by mass per 100 parts by mass of the binder, the above-mentioned lubricity and heat resistance are good, and particularly, the range of 5 to 15 parts by mass is preferable. I like it. If it is less than this range, no improvement in heat resistance is observed, and fusion is observed in the thermal head. On the other hand, if it exceeds this range, the back layer has reduced luck and film strength.
- the average particle size of the filler is also important, and varies depending on the thickness of the back layer to be formed, but is preferably in the range of 0.05 to 5 zm. If the average particle size exceeds 5 zm, wear of the thermal head is likely to progress, and when the filler is dissociated from the back layer, printing flaws generated on the printing screen become remarkable. On the other hand, if the average particle size is smaller than 0.05 x m, it is not preferable because the cleaning property when scum adheres to the thermal head is inferior.
- the above-described material is added to a binder solvent, for example, toluene / ethanol.
- the coating amount of the back layer is 0.7 gZm 2 or less on a dry solid basis, and preferably a thickness of from 0.9 to 0.6 gZm 2 to form a back layer having sufficient performance. If the thickness of the back layer is too thin, the function of the back layer cannot be sufficiently exhibited. On the other hand, if the back layer is too thick, the sensitivity at the time of printing decreases, which is not preferable.
- a transfer ink layer formed on the other surface of the base film in the case of a sublimation type thermal transfer sheet, a layer containing a sublimable dye, that is, a heat sublimation dye layer is formed, while a heat melting type In the case of a thermal transfer sheet, a heat-fusible ink layer colored with a pigment or the like is formed.
- a sublimation type thermal transfer sheet will be described as a representative example, but the present invention is not limited to only a sublimation type thermal transfer sheet.
- any dye conventionally used in a thermal transfer sheet can be used in the present invention, and is not particularly limited.
- some preferred dyes include MS RED G, Macro Red Vioret®, Ceres Red 7B, Samaron Red HBSL, Resolin Red F3BS as red dyes, and holon brilliant yellow 6GL as a yellow dye.
- PTY-52, Macrolex Yellow 6G, and the like and examples of the blue dye include Kaset Blue 714, Waxolin Blue AP_FW, Holon Brilliant Blue, —S_R, and MS Blue 100.
