METHOD FOR VARNISHING SUBSTRATES, AND VARNISHED SUBSTRATES
A method of producing a printed product, wherein a formulation for production of a first layer as sealing layer is applied to the substrate and the formulation has at least one monomer, oligomer or prepolymer having at least one crosslinkable functional group. Subsequently, the first layer is cured and a second layer is applied at least to regions of the first layer, wherein the second layer has a coherent surface in the printed regions. Further, a printed product having a substrate, a first layer and a second layer, wherein the first layer and the second layer comprise an organic crosslinked lacquer and have a coherent surface, and wherein the first layer is transparent and has a layer thickness in the range from 1 to 10 μm. The second layer has been applied at least to regions of the first layer, such that the first layer is disposed between the substrate and the second layer.
PRINTING SHEET AND METHOD FOR PRODUCING PRINTING SHEET
Provided are a printing sheet that has excellent printability, excellent adhesiveness between a substrate and a coating layer, and excellent antistatic performance and thus is less likely to cause troubles such as paper jams during printing, and further has excellent properties such as water resistance and weather resistance in the printing sheet having the coating layer for receiving an ink on at least one surface of the substrate and a method for producing the same. The printing sheet includes the coating layer by blending clay in a proportion of 35% by mass or more and 65% by mass or less and light calcium carbonate in a proportion of 5% by mass or more and 30% by mass or less in a continuous phase made of an acrylic polymer.
Image transfer material and polymer composition
Provided is an image transfer material, comprising a support, optionally at least one barrier layer, a melt transfer layer, and an image receiving layer. Also provided is a process for preparing the image transfer material. Further provided is a heat transfer process using the disclosed material. In the heat transfer process, after imaging, the image receiving layer and melt transfer layer are peeled away from the optionally barrier-coated support material and placed, preferably image side up, on top of a receptor element. A non-stick sheet is then optionally placed over the imaged peeled material and heat is applied to the top of the optional non stick sheet. The melt transfer layer then melts and adheres the image to the receptor element. A composition comprising: at least one self-crosslinking polymer, and at least one dye retention aid.
Curable liquids and inkjet inks for food packaging applications
A radiation curable liquid includes at least one free radical polymerizable monomer or oligomer, at least one diffusion hindered acetalyzation catalyst, and at least one diffusion hindered hydroxyl containing compound. The radiation curable liquid applied to a substrate prevents migration of very low viscous monomers, such as vinyl ether acrylate monomers, into the substrate.
