Abstract: The paper composite contains: a paper substrate having an air permeation resistance of 1,000 sec or less and bulk density of from 0.5 to 1.0 g/cm3; and a greaseproof layer on at least one side thereof, the greaseproof layer containing an ethylene-vinyl alcohol polymer (A) and a cationic fluorine-containing polymer (B) having two specific constitutional units. A content of the copolymer (B) in the greaseproof layer is from 5 to 50 parts by mass with respect to 100 parts by mass of the polymer (A), an amount of the greaseproof layer on dry mass basis is from 0.1 to 3.0 g/m2, and a water vapor permeability of the paper composite is 1,000 g/m2·24 h or greater.

Abstract: An ethylene/tetrafluoroethylene copolymer sheet obtained by extrusion, has R0/d, wherein R0 is an in-plane phase difference [unit: nm]and d is a thickness, [unit: nm], of at most 3.0×10−3, and a thickness of more than 300 μm. The ethylene/tetrafluoroethylene copolymer sheet preferably has a thickness of from 305 to 3,000 μm . A process for producing an ethylene/tetrafluoroethylene copolymer sheet includes melting an ethylene/tetrafluoroethylene copolymer to obtain a melt, continuously extruding the melt through a die for shaping the melt to a sheet, and letting the sheet pass between two rolls. One of the two rolls is a rigid roll, and the other is an elastic roll. The two rolls are pressed under a linear pressure of from 0.1 to 1,000 N/cm.

Abstract: To provide a water/oil repellent composition whereby it is possible to obtain an article which is excellent in each of water-repellency, oil-repellency, washing durability, heavy rain durability and texture, a method for producing said composition, and an article which is excellent in each of water-repellency, oil-repellency, washing durability, heavy rain durability and texture. The water/oil repellent composition comprises a copolymer having units based on a monomer (a), units based on a monomer (b) and units based on a monomer (c), and a liquid medium. Monomer (a): a compound represented by (Z—Y)nX (Z: a C1-6 perfluoroalkyl group, etc.; Y: a divalent organic group, etc.; n: 1 or 2; X: a polymerizable unsaturated group). Monomer (b): a (meth)acrylate having no polyfluoroalkyl group and having an alkyl group with at least 20 carbon atoms. Monomer (c): a compound represented by CH2═CR1C(O)O—[(C2H4O)a(C4H8O)b]—H (R1: a hydrogen atom or a methyl group, and a/b=1 to 3).
