An ink contains a pigment dispersed with polymer, a surfactant, a water-soluble organic solvent, and water. The mass ratio of a content of the pigment to a content of the polymer in the ink is more than 3. The surfactant includes a fluorinated surfactant which is represented by Formula (1) and which has an HLB of 11 or less as determined by a Griffin method. The water-soluble organic solvent includes at least one selected from specific Group A. The total content of the water-soluble organic solvents of the Group-A in the ink is larger than the total content of water-soluble organic solvents other than the water-soluble organic solvents of Group A in the ink.

The invention relates to multi-layer thermoplastic composites, and in particular composites having fluoropolymer in the outer layer and a thermoplastic substrate layer. The fluoropolymer outer layer may either be a layer comprising a majority, and preferably 100 percent fluoropolymer, or may be a blend of a thermoplastic matrix with fluoropolymer at a level of from 5 to 60 weight percent, based on the total weight of all polymers. Especially useful thermoplastic matrices include acrylic polymers, and styrenic polymers, especially styrenic copolymers such as acrylonitrile/styrene/acrylate (ASA), acrylonitrile/butadiene/styrene (ABS) and styrene/acrylonitrile (SAN). While the fluoropolymer may be any fluoropolymer, thermoplastic fluoropolymers, such as polymers and copolymers of polyvinylidene fluoride are especially useful. The improved flame retardant composite of the invention is especially useful in cap layers over plastic substrates, such as for flame-retardant plastic decking, railings, posts, fencing, siding, roofing, and window profiles.
摘要:
There is provided a composition for forming an underlayer film used for an underlayer of a self-organizing film. An underlayer film-forming composition of a self-organizing film, the underlayer film-forming composition comprising: a polymer consisting of a unit structure derived from an optionally substituted styrene and a unit structure derived from a crosslink forming group-containing compound, the polymer containing 60 mol% to 95 mol% of the unit structure derived from the styrene and 5 mol% to 40 mol% of the unit structure derived from the crosslink forming group-containing compound relative to the whole unit structures of the polymer. The crosslink forming group is a hydroxy group, an epoxy group, a protected hydroxy group, or a protected carboxy group. The crosslink forming group-containing compound is hydroxyethyl methacrylate, hydroxyethyl acrylate, hydroxypropyl methacrylate, hydroxypropyl acrylate, hydroxystyrene, acrylic acid, methacrylic acid, glycidyl methacrylate, or glycidyl acrylate.

The present invention provides for a radiation curable composition comprising at least one ethylenically unsaturated compound (A), and at least one inert copolymer (B) that is obtained by an addition reaction of: (b) from 3 to 50% by weight of at least one monofunctional glycidyl ether (b1) and/or at least one monofunctional glycidyl ester (b2) of aliphatic saturated monocarboxylic acids during the free radical polymerization of: (b') from 50 to 97% by weight of at least two ethylenically unsaturated copolymerizable monomers of which at least one contains at least one -COOH group (b'1),
wherein the quantity of -COOH groups in component (b'1) is at least equimolar to the quantity of epoxy groups in component (b), and wherein the amount of solvents in the radiation curable composition of the invention is below 10% by weight. The present invention further relates to their making and their use in coating compositions, adhesives, inks and varnishes.
