A method for preparing a proof for plate printing, which comprises applying inkjet printing to an ink receiving layer of a recording medium having the ink receiving layer formed on the surface of a support made of plate printing paper for regular printing or made of paper having substantially the same brightness and glossiness as such plate printing paper, to obtain a printing proof.

Method for preparing proof for plate printing, and recording medium

A process for preparing an aqueous dispersion, which comprises subjecting a monomer to emulsion polymerization in an aqueous medium in the presence of a fluorine-containing copolymer comprising units derived from a fluoroolefin, and units having a hydrophilic side chain.

Process for preparing an aqueous dispersion, aqueous dispersion and

A thermosetting powdery coating composition which comprises, in admixture: (A) from 40 to 98 parts by weight of a fluorine-containing copolymer, which is a copolymer of a fluoroolefin and a comonomer having a crosslinkable reactive group, e.g., hydroxy, carboxyl, amino and glycidyl groups, containing at least 10% by weight of fluorine and having an intrinsic viscosity of 0.05-2 dl/g (30.degree. C., tetrahydrofuran), a glass transition temperature of 30.degree.-120.degree. C. and a weight loss by heating which does not exceed 2% and (B) from 60 to 2 parts by weight of a curing agent capable of forming crosslinks by reacting with the crosslinkable reactive groups in (A), except for the composition wherein (A) is a hydroxyl group and a weight loss by heating which does not exceed 2% and (B) is a blocked isocyanate compound. The powdery coating composition is excellent in the dispersibility of pigments and efficiency in the coating works therewith and capable of giving a coating film having improved adhesion to a substrate surface, surface luster, impact resistance and insusceptibility to staining.
