摘要:
An improved ink-jet recording medium comprising a base paper substrate coated with a radiation-curable layer having a relatively low glass transition temperature (Tg) and at least one ink-receptive layer is provided. The radiation-curable layer can be cured with UV-light radiation. The ink-receptive layers are coated over the radiation-cured layer. The radiation-cured layer is generally flexible so that the resulting ink-jet recording medium can be handled and packaged easily. The ink-jet recording medium can be printed with images using ink-jet printers. The medium has improved ink-drying times and ink-smudge resistance.

摘要:
A photocurable ink for ink-jet printing, including: a photopolymerizable compound; a pigment; and a dispersing agent, wherein the photopolymerizable compound is a radical polymerizable compound; an amine value of the pigment (AMp) is larger than an acid value of the pigment (ACp); and an acid value of the dispersing agent (ACd) is larger than an amine value of the dispersing agent (AMd).
摘要:
The present invention is directed to a powder coating composition that produces a low gloss coating upon cure. The powder coating composition includes one or more crosslinkable base polymer, a crosslinkable acrylic polymer and one or more free radical initiators. By adding spheroidal particles to the powder coating composition further reduction in gloss can be obtained while improving smoothness. These compositions are well suited to produce coatings on metallic substrates, such as automotive bodies and non-metallic substrates, such as reconstituted wood substrates, used for desk or table tops.
摘要:
Quick-drying, solvent-based coating compositions, which are curable by UV-A radiation and contain at least one amorphous polyurethane with a glass transition temperature of from 35° C. to 100° C., the proportion by weight of soft groups in said amorphous polyurethane being less than 30 wt. %. The compositions are prepared by mixing all of the components that are free of isocyanate groups, and mixing in the components that contain free isocyanate groups just before application to a substrate.
摘要:
A description is given of water-soluble aminoplast ether copolymers of the following structural type: where Z is an aminoplast unit based on a glycoluril which is unsubstituted or substituted by a reactive OR group (where R is an alkyl, alkylene, alkyl ether or alkyl ester group, preferably a lower alkyl group, e.g., a methyl or ethyl group); B is the radical of an essentially water-insoluble polymer selected from poly-n-butyl acrylate, poly-n-butyl methacrylate, polyethyl acrylate, polytetrahydrofuran, polyethyl methacrylate, polymethyl acrylate, polymethyl methacrylate, a predominantly aliphatic polycarbonate or a predominantly aromatic polycarbonate, and more preferably from a poly-n-butyl methacrylate or a predominantly aliphatic or aromatic polycarbonate having at least two functional groups which are able to react with the OR function of the aminoplast unit, preferably having a hydroxyl function; R1 is the radical of a hydrophilic organic compound containing at least one functional group which is able to react with the OR function of the aminoplast unit to form an ether bond, preferably having a hydroxyl function, and a is at least 1. A description is additionally given of a process for preparing the above aminoplast ether copolymers and also of their use as dispersants and stabilizers.
