  • Patent number: 7651759
    Abstract: The invention relates to a digital printing method and a paper or board applicable thereto. In digital printing, the surface of a paper or board is charged electrically, toner particles are brought to the surface in an electric field in accordance with the printing, and the particles are melted fast to the surface with the help of heat for forming the printing. According to the invention, the paper or board (2) is provided with a coating layer (3) containing an electrically chargeable acrylate copolymer of ethylene, which receives the toner that is fused to the coating with the help of infra red radiation. Suitable coating polymers are especially methyl, ethyl and butyl acrylate copolymers of ethylene (EMA, EEA and EBA). Especially in packaging boards, besides the digitally printable layer, the polymer coatings can comprise a water vapour or oxygen barrier layer for protecting the packed product, and a heat-sealable layer on the opposite side of the board for sealing the package.

Treatments, such as aqueous-based treatments and/or emulsions, can be applied to the surface of a substrate, such as paper-based materials, which can be dried to form a treatment layer imparting grease resistant properties. In some instances, the treatment includes an acrylic-based polymer, which can impart grease-resistance, and one or more complementary components (e.g., a polymer and/or oligomer) that can make a layer less brittle (e.g., lowering the Tg of the layer relative to a layer of acrylic-based polymer). Such treatment layers can retain their grease resistance even when creased, allowing the use of such layers in applications such as food processing. Other additives, compositions, and methods are further developed.

  • Patent number: 7384674
    Abstract: A packaging laminate for a retortable packaging container, the packaging laminate (30) including a paper or paperboard layer (31), outer, liquid-tight coatings (32; 33) and an aluminium foil (34) serving as gas barrier between the paper or paperboard layer (31) and one of the two outer liquid-tight coatings (32). In order to compensate for or counteract possible loss of gas tightness because of crack formations or similar untightness in the tensile-sensitive aluminium foil (34), the packaging laminate (30) includes at least one additional layer (35) serving as gas barrier between the paper or paperboard layer (31) and the aluminium foil (34).

  • Publication number: 20080107912
    Abstract: The invention relates to coated products for printing on including a substrate and at least two different coatings having different properties, which comprise a low-coat layer, adjacent to the substrate, preferably pigmented, for printing properties and possibly optical properties, and a different top-coat layer, farther from the substrate, comprising optical pigments for optical effect properties, each coating having a dry coatweight ranging from 0.1 to 12 g/m2. The invention also concerns a one-pass wet-on-wet multi-layer curtain coating process for producing said coated products suitable for printing on.

  • Patent number: 7320831
    Abstract: A salt sensitive polymeric binder for use in fibrous webs, where the binder contains a copolymer incorporating the residue of vinyl acetate, a carboxylic acid, and a vinyl ester of a saturated aliphatic monocarboxylic acid having between 6 and 18 carbon atoms in the carboxylic acid moiety. The copolymer is neutralized at least to the extent that it is water soluble. The binders are particularly suitable for strengthening non-woven fibrous webs in disposable articles such as wet-wipes, personal care products, diapers, and the like.

  • Patent number: 7297306
    Abstract: A new class of amines is incorporated into phtopolymerizable systems employing type I or type II photoinitiators. These amines are trialkylamines having a total of 10 to about 36 carbon atoms in the molecule and wherein at least one alkyl group has a chain length of at least 8 carbon atoms. Preferably, one or two of the alkyl groups are methyl or ethyl or one of each. Short chain amines as defined herein provide synergistic results when used with such trialkylamines.

  • Patent number: 7291400
    Abstract: The present invention improves a surface protective layer in the resistance to marring to the extent not achieved even if the surface protective layer is made of a crosslinked cured product of an ionizing radiation-curable resin and added with silica. When forming a layer comprising the crosslinked cured product of the ionizing radiation-curable resin as a surface protective layer (2) on a substrate sheet (1) made of paper or the like, fired kaolin is contained as a filler in the surface protective layer. The fired kaolin is preferably surface-treated with a silane coupling agent. On the substrate sheet (1), a wholly solid layer (3) and a pattern layer (4) are generally provided. A primer layer may be optionally provided between the substrate sheet and the surface protective layer.

  • Patent number: RE40857
    Abstract: A recording medium particularly suitable for electrophotographic copying is characterized by coated paper that for a given basis weight has proportionally less coating and proportionally more fiber than conventional coated paper made for electrophotographic processes. The base sheet of the coated paper is preferably formed square on a paper machine wet end and has on the order of 40-50% less filler than conventional sheet paper made for electrophotographic processes. After being formed and dried, the base sheet is provided with a top coat weight that is approximately 60% less than the typical coat weight used for conventional paper. The coating is formulated to have sufficient viscosity to stay more on the surface of the base sheet. The coated sheet is calendered to a medium gloss on the order of a 75° TAPPI gloss of about 45, both to preserve a degree of surface roughness to enhance runnability of the paper through an electrophotographic copier and to provide a pleasant and easily readable surface.
