Description
Technical field
The present invention relates to print image and transfer to target substrate, especially the method on billboard, cystosepiment or the rigid PVC.
Background technology
Developed multiple technologies and be used for the image that the document form that computer can read is caught in digitlization, used the computer edited image, the image of Computerized Editing has been printed on the recording medium, then image has been transferred on the target substrate from recording medium.Target substrate can be to comprise a kind of in many materials of the fabric, ceramic material, billboard, rigid PVC or the fixed head that are widely used in graphical arts industry such as cystosepiment or foam PVC plate.
The typical record medium that is used for accepting and shifts the image that is formed by ink-jet printer has the two-layer at least of carrier and following coating: adherent layer, protective barrier layer, image transfer layer and adhesive phase.International Patent Application PCT/the GB98/00481 that proposes about 16 days February in 1998 of " transfer membrane " has described the carrier with transfer membrane that one deck is only arranged.This simple layer is hot activable adhesive particle and also is the mixture of the binding agent of absorbency, thereby determines porous matrix.When being used for business graphics and using, this transfer membrane can be adhered on the target substrate, need not remove carrier, so carrier pastes on the layer with print image, thereby provides physical protection to image.
Just " printable laminate " U.S. patent application 09/107,302 (its disclosure is introduced for reference here) of proposing was described and was used to shift the image that produced by the ink-jet printer printable laminate material on the target substrate on June 30th, 1998.This printable laminate has carrier film, comprises the image recording layer of the adhesive of ink absorbent and thermal activation in the setting of one side.Ink absorbent is a modified cellulosic materials, yet also can use carboxymethyl cellulose or single water-soluble polymer of planting the band cationic charge.The adhesive of thermal activation is a polyurethane.In above-mentioned 302 applications, the polyurethane of image recording layer is the form of fine rule spline structure, and they are distributed in the whole ink absorbent, thereby have formed uniform mixture with the ink absorbent of recording layer.
U.S. patent 5,501, and 902 described can be at the multilayer printable material for transfer of 177 ℃ of following use flatirons sealings.Yet for using with the common fixed head that is used for graphical arts industry, this temperature is too high.In addition, ' 902 patents have been described and have been used the granularity powdery polymer of 20 μ m at the most.Coarsegrain trends towards producing the printing image with graininess outward appearance, and the result has caused the loss of definition, contrast and the lightness of printing image.
International Patent Application WO 98/02314 has been described the printable material for transfer that can peel off from interim carrier, and wherein the image of Zhuan Yiing is a waterproof.It is the oarse-grained porous matrix of 20 μ m that this material uses typical size.Material for transfer stands high temperature (general 190 ℃) to form the film of polymer, and printing ink is encapsulated in film inside.
Especially the anti-carrier thin film of printable laminate has been carried out further investigation from the ability of image recording layer separation or leafing at International Application PCT/GB98/00481 and U.S. patent application 09/107,302 invention disclosed.Find, in some commercial advertisement display boards, cut off or often cause that the protection carrier layer separates during cutting printable layer casting die from recording layer for the suitable size image that obtains to show usefulness or for the still image that obtains to have irregular contour.
Carrier thin film separation in these cases as if owing in cutting-off process by shearing, tension force and compression stress that cutting blade applied.When the pulling blade passed printable laminate, these power reached the top, and when the power that is applying in the shearing material was enough to overcome the bonding yield point of image transfer layer, the adhesive structure between image recording layer and carrier layer went to pot.
When destroying, carrier thin film separates from image recording layer, and the protective action that is provided by carrier layer will lose.And the separation of carrier layer can reduce the quality of print image largely, and reason is that this separation can cause " silvery white " effect, but the outward appearance of its hidden image or impairment image.
Summary of the invention
