摘要： This invention provides polypropylene-based resin-coated paper using paper as substrate and having excellent smoothness, especially the one which, when used for printing or heat transfer recording, keeps free from formation of white dots and occurrence of density unevenness in images, and thus is suited for printing use or heat transfer recording use. At least one side of the paper substrate is coated with a resin. The paper used as substrate is characterized by the fact that the unevenness in film thickness in machine direction (unevenness index) as measured by a film thickness meter is less than a specified value. The resin used for coating is a compounded resin composition comprising a polyethylene-based resin and a random polypropylene-based resin obtained by randomly copolymerizing principally ethylene and propylene, with the ethylene proportion being in a specified range, wherein the ratio by weight of the polyethylene-based resin to the random polypropylene-based resin is in a specified range, and the composition has been subjected to at least one round of kneading.

摘要： A pre-treatment fixing fluid for an offset coated medium is disclosed. The pre-treatment fixing fluid includes calcium-containing cationic crashing agents consisting of calcium propionate and calcium nitrate, wherein the calcium propionate is present in an amount ranging from about 0 wt % to about 10 wt %, and wherein the calcium nitrate is present in an amount ranging from about 15 wt % to 0 wt %, both based on the total wt % of the pre-treatment fixing fluid. The pre-treatment fixing further includes a co-solvent, a surfactant, and a balance of water. The surfactant is selected from the group consisting of a first surfactant having a first hydrophilic lipophilic balance (HLB) value within a hydrophobic range and a combination of the first surfactant and a second surfactant having a second HLB value within a water dispersible range.

摘要： The present invention relates to a coated paper product and method for making the coated paper product. The product comprises a paper substrate, which can be of a low quality, that is coated with at least two layers of coating in one embodiment. A first coating layer is applied to the front and back sides of the paper substrate before a second coating layer is applied. The first coating layer comprises titanium dioxide, an aluminum silicate, calcium carbonate, clay and a binder. The second coating layer comprises hollow spherical particles, which provides the coating with an improved ability to spread while improving the coverage and formation of the coating layer, and also comprises a printing additive, titanium dioxide and a binder.
