An ink jet recording sheet which absorbs water-base ink well, gives high-grade images, and ensures excellent water resistance of printed images. The ink jet recording sheet comprises a substrate and an ink receptive layer disposed on the substrate, the ink receptive layer containing a pigment and a binder as its main components, the improvement comprising the ink receptive layer being an aqueous composition containing a pigment and an ampho-ion latex as its main components.

Ink jet recording sheet

A printed film sheet in which an image printed on a transparent film sheet can be seen from both the printed side and the non-printed side of said film sheet. The transparent film sheet is provided with a coating composition containing one or more pigments and one or more adhesives so that said film sheet has a brightness of above 50%. The pigments include one or more pigments having a linseed oil absorption of 10 to 80 ml/100 g in an amount of 70 to 100% by weight of the total pigment content. The film sheet has an opacity of 20 to 60% and is printed so that the difference between the ink density of a printed image on the printed side of said film sheet and the ink density thereof on the non-printed side of said film sheet is below 35%.

Printed film sheet

An ink jet recording sheet comprises on a film substrate a coating layer which contains a pigment component and a binder component. The pigment component comprises prismatic orthorhombic aragonite calcium carbonate having an oil absorption of 30 to 55 ml/100 g in an amount of 20 to 70 weight %. The binder component comprises an epoxy resin and a thermoplastic resin.

A matted transparent paper is obtained by moistening a paper prepared from relatively lightly beaten pulp and then subjecting the moistened paper to a calendering treatment with the use of a heated embossing metal roll having a finely engraved surface with sharp reliefs.

Method for the production of a matted transparent paper and the product

A matted transparent paper is obtained by moistening a paper prepared from relatively lightly beaten natural pulp and then subjecting the moistened paper to a calendering treatment with the use of a heated embossing metal roll having a finely engraved surface with sharp reliefs.

The surface of a paper material is treated with an aqueous composition comprising a water soluble polymer and a polymer emulsion, said paper material being formed of a fibrous material, at least a part of which is composed of hydrophilic polyolefin fibers. The obtained product has a strong pick resistance and an improved ink receptivity adapted for offset printing.

Method for the production of a synthetic fiber paper having an improved

A coated synthetic paper adapted for offset printing is produced from a base paper sheet comprising fibrous material, at least 5% by weight of which is formed of polyolefinic pulp fibrils which are formed from a polyolefinic polymer and a hydrophilic polymer, said polyolefinic pulp fibrils having a specific surface area of at least 0.7 square meter/g. A microporous and discontinuous coating layer is formed on at least one of the surfaces of the base paper sheet using a coating composition having an adhesive component and a pigment component, at least 5% by weight of said pigment component being an organic polymer pigment in the form of finely divided particles.

Coated synthetic paper adapted for offset printing and method for

The electrostatic recording material comprises an electroconductive transparentized base sheet having a dielectric layer thereon. The transparentized base sheet is obtained by subjecting to a transparentizing treatment with moisture, heat and pressure a fibrous matrix sheet of a mixture of natural pulp with synthetic pulp formed of a blended polymer system consisting essentially of polyvinyl alcohol-acrylonitrile copolymer and acrylonitrile-styrene copolymer.
