Abstract: Disclosed is a metallic pigment composition which can provide, when used in a coating composition, an ink composition or the like, in particular, a water-based coating, a water-based ink or the like, a coating film having a high storage stability, a good adhesiveness, a good chemical resistance and a good color tone. Specifically disclosed is a metallic pigment composition which comprises at least one kind of compound selected from a heteropolyanion compound and a mixed-ligand heteropolyanion compound, an organic oligomer or polymer, and metal grains.

Abstract: Provided is a metallic-pigment composition which is usable in coating compositions or ink compositions, in particular, in water-based coating compositions or aqueous inks, and which gives coating compositions having excellent storage stability. The metallic-pigment composition gives a coating film having excellent performances with respect to brightness, hiding properties, flip-flop feeling, etc., causes no colorant or organic-pigment discoloration, and has excellent adhesion and chemical resistance. The metallic-pigment composition comprises one or more mixed-coordination-type heteropolyanion compounds, a hydrolyzate of a silicon compound and/or a condensate thereof, and metal particles.

Abstract: Disclosed is a crosslinking resin composition comprising: (A) a carboxyl group-containing resin as a main agent, having a number average molecular weight of from 1,000 to 40,000 and an acid value of from 10 to 400 mg KOH/g; (B) a cyclic or chain silicone compound as a curing agent, having a number average molecular weight of from 350 to 8,000 and containing at least two epoxy groups in one molecule thereof, wherein the silicone compound is free of a silanol group, a hydrolyzable silyl group and a vinyl polymer structure, and wherein the silicone compound has a siloxy group-containing skeleton; and (C) a medium. The crosslinking resin composition of the present invention not only exhibits excellent storage stability, but is also capable of providing, upon being crosslinked, a cured resin having excellent gloss, weatherability, acid resistance, solvent resistance, water repellency and stain resistance.

Abstract: A fluorine-containing resin being soluble in an organic solvent and having excellent compatibility with a curing agent, which contains Component (A) formed of a unit having the formula ##STR1## and at least one of Component (B) formed of a unit having a cyclic hydrocarbon group introduced through a urethane bond in the molecule and Component (C) of a unit having the formula ##STR2## and which further optionally contains Component (D) of a unit formed from a vinyl monomer having a specific functional group, Component (E) of a unit formed from a vinyl monomer other than monomers forming the Components (A), (B), (C) and (D), and Component (T) of a unit formed from an acrylic resin having a specific substituent; and a coating composition containing said resin, (wherein V, Y, X, Z, R.sup.c1, R.sup.c2 and R.sup.c3 are as defined in the specification).

Abstract: A novel isocyanurate polyisocyanate is disclosed containing N,N',N"-tris(6-isocyanatohexyl)-isocyanurate in an extremely high proportion and having an extremely low viscosity. The novel isocyanurate polyisocyanate is excellent not only in compatibility with a polyol having a low polarity but also in solubility in a solvent having a low polarity as well as in a polar solvent. The novel isocyanurate polyisocyanate is very useful as a curing agent for a two-component polyurethane composition, especially a two-component polyurethane coating composition. The two-component polyurethane coating composition of the present invention is capable of providing a coat film having extremely excellent properties.
