[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail with reference to preferred embodiments of the present invention.
The support used in the present invention is particularly limited as long as it has sufficient strength to support the water-resistant release layer and the ink receiving layer, and if necessary, has heat resistance, water resistance, solvent resistance and the like. Examples include paper, plastic films such as PP (polypropylene), PET (polyethylene terephthalate), nylon, and acetate, or natural or synthetic fibers. However, if workability in the subsequent transfer process is taken into consideration, paper is used. It is preferable to use a plastic film.
[0009]
A water-resistant release layer is releasably coated on the surface of the support. Examples of the water-resistant release layer include silicon, wax, resin, etc., but considering the workability in the later transfer process and the durability of the image in the transfer layer on the transfer product obtained in the transfer process, A resin component is selected. The water-resistant release layer may have temporary adhesive properties that can be re-peeled to the support.
[0010]
As the resin component constituting the water-resistant release layer, those made of an acrylic resin in particular are peelable from the support in the transfer process, the durability of the image in the transfer layer on the obtained transfer product, water resistance, etc. Is needed to secure Component monomers of the acrylic resin include (meth) acrylic acid, (meth) acrylate, methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, lauryl (meth) acrylate, 2-ethylhexyl. Examples include (meth) acrylic acid alkyl esters such as (meth) acrylate, (meth) acrylic acid hydroxyalkyl esters such as hydroxyethyl (meth) acrylate, hydroxypropyl (meth) acrylate, and hydroxybutyl (meth) acrylate. However, among them, those having (meth) acrylic acid alkyl esters as the main component have better peelability from the support in the subsequent transfer process and water resistance of the image in the transfer layer on the obtained transfer product. is there. The water-resistant release layer may be mixed with a plasticizer or a release agent. The acrylic resin may contain a monomer other than an acrylic monomer (for example, styrene, vinyl acetate, etc.) that is copolymerizable with an acrylic monomer as a part of the component monomer.
[0011]
Further, an ink receiving layer is coated on the surface of the water-resistant release layer. The ink receiving layer absorbs and fixes water-based ink, and contains a resin component in order to improve the absorbability and fixability of the water-based ink, and an acrylic resin is selected as such a resin component. The ink receiving layer may contain porous inorganic particles and a surfactant as necessary.
[0012]
Further, the ink receiving layer softens and absorbs water by absorbing water-based ink, and such an ink receiving layer has the adhesive property without using heat or the like in the transfer process. It can be used to adhere to the surface of the transfer object.
[0013]
As described above, as a resin component that enables particularly good adhesion to a transfer target using the adhesiveness generated by ink absorption, and that has excellent ink absorption and fixing properties, N, N-dimethylamino is used. Ethyl (meth) acrylate, N, N-diethylaminoethyl (meth) acrylate, N, N-dimethylaminopropyl (meth) acrylate, N, N-dimethylaminoethyl (meth) acrylamide, N, N-dimethylaminopropyl (meth) ) An acrylic resin having an amino group-containing (meth) acrylate such as acrylamide as a component monomer is selected.
The acrylic resin may contain a monomer other than an acrylic monomer (for example, styrene, vinyl acetate, etc.) that is copolymerizable with the acrylic monomer as a part of the component monomer.
[0014]
In particular, as an acrylic resin that has absorptivity and fixability to water-based inks and produces adhesiveness by absorbing water-based inks, those obtained by polymerizing amino group-containing acrylic monomers alone, or amino group-containing acrylics A monomer obtained by copolymerizing another acrylic monomer with a system monomer is selected. In this case, the ratio of the amino group-containing acrylic monomer in the acrylic resin must be 5 to 100% by weight in the component monomers, and particularly excellent water-based ink absorbability and fixability within this range. Show.
[0015]
Moreover, what consists of amphoteric acrylic resin can be used suitably as said acrylic resin. Examples of the monomer component include a resin containing an amino group-containing acrylic monomer and a carboxyl group-containing monomer, and an acrylic resin having a betaine type or sulfobetaine type group.
One or both of the water-resistant release layer and the ink receiving layer sequentially coated on the surface of the support may contain an ultraviolet absorber in order to ensure the light resistance of the image formed by the ink jet. Various other additives may be added.
[0016]
The film thickness of the water-resistant release layer or ink receiving layer is not particularly limited. For example, when the support is made of a general PET film or other resin film or paper, the film thickness of the water-resistant release layer formed by coating or the like on the support is preferably 1 to 1 in a dry state. The thickness is 100 μm, particularly preferably 1 to 60 μm, and most preferably 3 to 30 μm.
When the film thickness of the water-resistant release layer is in the above range, particularly, the water-resistant release layer and the support cannot be peeled off well during the transfer process, or the water-resistant release layer is cracked at the time of peeling. In addition, problems such as insufficient water resistance of the image in the transfer layer on the transfer product are unlikely to occur.
[0017]
The film thickness of the ink receiving layer formed on the water-resistant release layer by coating or the like is preferably 1 to 70 μm, particularly preferably 1 to 50 μm in a dry state, and most preferably 3 to 30 μm. When the film thickness of the ink receiving layer is within the above range, the water-based ink has particularly good absorbability and fixability, and high-quality printing is possible. The problem that the water penetration of the internal image deteriorates and the water resistance of the internal image deteriorates hardly occurs.
[0018]
The ink-jet transfer medium obtained as described above can perform high-quality printing with an ink-jet printer because of the excellent ink absorbability and fixability of the ink receiving layer.
