Description
Technical Field
The invention belongs to the technical field of thermal sublimation printing, and particularly relates to a thermal sublimation retransfer film and a method for realizing a non-contact printing effect by using the thermal sublimation retransfer film.
Background
Short sheet printing of specialty papers has been a difficult problem with traditional printing. Because special paper generally has various paper types, a rough surface structure and different ink absorption amounts, and particularly, the printing of the special paper needs to print exquisite patterns on the premise of keeping the rough touch feeling of the surface of the paper, so that the general pressure printing cannot meet the requirements. Thermal sublimation dye printing is also a pressure printing method, in which a dye on a color ribbon is sublimation printed by heating to a coating with special dye receiving capability to present an image. The traditional sublimation dye printing pattern is exquisite, the image is fine, but a printing object must have a smooth and flat dye receiving layer to print. If a dye receiving layer is added on the special paper, the touch feeling of the paper can disappear, and the application requirement is not met.
Disclosure of Invention
In order to solve the defects in the prior art, the invention provides a thermal sublimation retransfer film and a method for realizing a non-contact printing effect by using the thermal sublimation retransfer film. The method for realizing the non-contact printing effect by using the thermal sublimation retransfer film can print the pattern on different special papers on the premise of ensuring exquisite pattern and touch feeling of paper.
The technical scheme provided by the invention is as follows:
a method for realizing a non-contact printing effect by using a thermal sublimation retransfer film comprises the following steps:
1) Printing an image onto a dye receiving layer of the thermal sublimation retransfer film provided by the invention using a thermal sublimation printer;
2) Transferring the image on the dye receiving layer to the surface of a target printing stock in a heating transfer printing mode;
3) And (3) carrying out hot pressing on the target printing stock with the image on the surface, heating and melting the image coating, and penetrating into the surface pores of the target printing stock.
The target printing object is special paper, such as pearlescent paper, gold paper, kraft paper, cloth paper, xuan paper, white cardboard, water line paper or Xuan paper. Common features of these specialty papers include: the roughness is 20-200ml/min.
According to the technical scheme, the pattern can be printed on the special paper by adopting a non-contact transfer printing mode through a thermal sublimation retransfer film technology, so that the problem that the pattern cannot be directly printed on the special paper by thermal sublimation printing in the prior art is solved. In addition, the method does not damage the original surface roughness structure or texture of the special paper, and the effect is achieved by adopting a hot pressing mode.
The target printing stock with patterns obtained by the method can be used as a soft label, a wine label or a packaging pattern, and the like.
The invention also provides a thermal sublimation retransfer film, which comprises a substrate, a release layer and a dye receiving layer which are sequentially arranged from bottom to top, wherein:
the material of the matrix is selected from PET, PP or PE, and a PET film with the thickness of 4.5-100 mu m is preferably used;
the release layer is made of at least one or more of polyester resin, polyurethane resin, polycarbonate resin or acrylic resin, and has a thickness of 0.5-5 μm;
the material of the dye receiving layer at least comprises polyvinyl chloride, polyvinylidene chloride, copolymer of vinyl chloride and vinyl acetate, vinyl chloride modified acrylic resin or chloroether resin, and the thickness of the material is 3-10 mu m.
< matrix >:
the thickness of the matrix is 4.5-100. Mu.m, preferably 12-25. Mu.m.
Generally, the PET film substrate may be subjected to pretreatment before coating, and the treatment means include an easy-to-adhere treatment such as corona discharge, plasma treatment, ozone treatment, flame treatment, primer (also referred to as anchor coat, adhesion promoter, easy-to-adhere agent) coating treatment, preheating treatment, dust removal treatment, vapor deposition treatment, alkali treatment, antistatic layer imparting treatment, and the like. The present invention generally uses corona treatment. However, the inventors have tested that no treatment has any significant effect on the properties of the final product.
< release layer >:
the release layer has three functions: firstly, when performing thermal sublimation image printing, adhesive force between a printing layer and a substrate PET is provided, so that the printing layer cannot be fused and bonded to a color ribbon under a heating state due to a coating; secondly, when the image printed in the first step is transferred onto the target paper, the demolding property is provided, so that the printing layer with the pattern can be smoothly separated from the transfer film and is adhered to the surface of the paper; and thirdly, after the second step is finished, the release layer can be used as a protective layer of the whole image to provide various resistances such as friction resistance, solvent resistance and the like.
In order to achieve the first step, resins having good adhesion to PET, such as polyester resins, polyurethane resins, polycarbonate resins, acrylic resins, and the like, may be selected.
Also, in view of the second step, it may further be preferable to include 1 to 5 parts by weight of a polyurethane resin and 1 to 5 parts by weight of an acrylic resin. In order to ensure that the release layer and the printing layer have good interlayer adhesive force, corresponding resin is matched, and the resin can be used for adjusting the adhesive force of the release layer on PET, and can also enhance the adhesive force of the release layer and the printing layer, so that the two layers are not separated after transfer printing. The resin can be selected from 5-10 parts of polyvinyl chloride, binary vinyl chloride, ternary vinyl chloride, vinyl chloride-modified acrylic resin, etc., and the vinyl chloride-modified acrylic resin are preferably selected from vinyl chloride-vinyl chloride resin and vinyl chloride-ether resin in consideration of the certain toughness required by the release layer. Through verification, the ratio of the two components can be adjusted between 1:1 and 1:9 according to the actual release effect, and the preferable range is 1:5 to 1:9.
Further, while the problem of release force adjustment is also considered, it is also necessary to add a certain amount of release force adjusting agent such as polyethylene glycol, polypropylene glycol, PE wax, beeswax, paraffin wax, carnauba wax, etc., and it is considered that the release layer is required to maintain good friction and solvent resistance after transfer is completed, polyethylene glycol and PE wax are preferable. The amount added is 1 to 20phr, preferably in a proportion of 5 to 15phr, of the resin.
The release layer is preferably coated to a thickness of 0.5 to 5. Mu.m, preferably 1 to 3. Mu.m.
And dissolving the raw materials by using 2-butanone and toluene to obtain the release layer coating, and then coating to form a release layer.
< dye receiving layer >:
the dye receiving layer is mainly used for receiving the sublimation dye, and the main resin is preferably halogenated resin such as polyvinyl chloride or polyvinylidene chloride, vinyl chloride-vinyl acetate copolymer, vinyl chloride modified acrylic resin and vinyl chloride ether resin, preferably vinyl chloride-vinyl acetate copolymer and vinyl chloride ether resin.
In order to prevent the problem of adhesion between the printing layer and the ribbon caused by resin melting due to heating during printing, a certain amount of anti-sticking agent is added into the printing layer to prevent sticking. Because the printing layer is closely contacted with the ribbon in the thermal sublimation printing process, the liquid lubricant in the printing layer can gradually migrate to the surface of the ribbon, and the risk of bonding the printing layer and the ribbon is gradually increased when the substrate at the same position is contacted with the ribbon for 3 times. In order to solve the problem, the invention adopts the following scheme: and adding a certain amount of two non-reactive silicone oils, wherein one silicone oil is 1-10 parts by weight of benzene ring modified polyether organic silicone oil, the silicone oil can provide good smoothness at a high temperature (about 200 ℃), and the other silicone oil is 1-5 parts by weight of epoxy modified organic silicone oil, and the silicone oil can provide good smoothness at a low-medium temperature. The coating provided by the invention can keep excellent smoothness when the coating is printed at different concentrations, so that the problems of halation and even fading of the color ribbon and the dye receiving layer caused by bonding are avoided during printing.
In order to further accommodate the high heat resistance required for high speed printing by thermal sublimation, the coating layer also needs to be crosslinked and cured to some extent. Optionally, an amount of Toluene Diisocyanate (TDI), isophorone diisocyanate (IPDI), diphenylmethane diisocyanate (MDI), dicyclohexylmethane diisocyanate (HMDI), hexamethylene Diisocyanate (HDI), lysine Diisocyanate (LDI), preferably Toluene Diisocyanate (TDI) and diphenylmethane diisocyanate (MDI), may be added to the coating. The amount added is from 1 to 10phr, preferably from 5 to 10phr. To accelerate the curing of the coating, it is also necessary to add a certain amount of curing aids containing hydroxyl groups, such as polyethylene glycol 200, polyethylene glycol 400, polyethylene glycol 600, polyethylene glycol 800, polyethylene glycol 2000, polyethylene glycol 8000, polyethylene glycol 20000 and polypropylene glycol 2000, hydroxyacrylic resins, trichloroacetic acid and the like, preferably polyethylene glycol 600 and polypropylene glycol 2000.NCO: the OH ratio is 0.1 to 1.2, preferably 0.3 to 0.7.
Further, in order to improve the adhesion of the dye-receiving layer to the paper, it is also necessary to add an amount of adhesion promoter. Chlorinated polypropylene resin, ethylene-vinyl acetate copolymer, polyamide resin, CPP modified acrylic resin, rosin resin, chlorinated EVA resin, phenolic resin, rosin modified phenolic resin, maleic anhydride modified CPP resin, etc. can be selected, CPP, polyamide and EVA resin are preferable, and the addition amount is 1-20phr of resin. Other auxiliary resins may be added to ensure that the heat resistance is not degraded.
To further increase the resistance of the coating, amounts of antistatic agents and UV absorbers may also be added.
The print substrate is preferably coated to a thickness of 3 to 10. Mu.m, preferably 5 to 7. Mu.m.
