Abstract: An automotive clear coating composition includes a hydroxyl group-containing acrylic resin obtained using hydroxyalkyl(meth)acrylate having a hydroxyalkyl group having 4-9 carbon atoms as at least a part of its monomer; and a polyfunctional isocyanate compound in which at least a part thereof is an isocyanurate type isocyanate compound. The prepared composition has 25 to 50 mass % of a soft segment part with respect to a total solid content of such acrylic resin and the polyfunctional isocyanate compound, and a ratio of a soft segment part derived from a lactone-containing monomer with respect to the total solid content of such acrylic resin and the polyfunctional isocyanate compound of not more than 4.5 mass %. A cured coating film has a dynamic glass transition temperature within a range of 30 to 60° C. The soft segment part is represented by —CH2)n— wherein n represents an integer of 4 or more.

Abstract: The great decrease of the curing time (in particular, halving) of acid/epoxy curing system paint and the further improvement of other performances (in particular, film performance). A two packages type thermosetting resin composition comprising (a) an acid anhydride group-containing acryl resin having an acid anhydride group of 0.08 to 5.3 mmol/g (solid content) and a number average molecular weight of 500 to 8000 that is obtained by copolymerizing an acid anhydride group-containing ethylenically unsaturated monomer with an ethylenically unsaturated monomer having no acid anhydride group, (b) a carboxylic group-containing polyester resin having a carboxylic group of 0.8 to 6.3 mmol/g (solid content) and a number average molecular weight of 400 to 3500 and a ratio of weight average molecular weight to number average molecular weight of 1.

Abstract: A clear coating composition for an automobile, including a hydroxyl group-containing acrylic resin and a polyfunctional isocyanate compound, in which: the hydroxyl group-containing acrylic resin is a hydroxyl group-containing acrylic resin obtained by using hydroxyalkyl(meth)acrylate having a hydroxyalkyl group with 4 to 9 carbon atoms as at least a part of its monomer; at least a part of the polyfunctional isocyanate compound is an isocyanurate type isocyanate compound; and the clear coating composition is prepared such that the clear coating composition includes 25 to 50 mass % of a soft segment part with respect to a total solid content of the hydroxyl group-containing acrylic resin and the polyfunctional isocyanate compound, a ratio of a soft segment part derived from a lactone-containing monomer with respect to the total solid content of the hydroxyl group-containing acrylic resin and the polyfunctional isocyanate compound is not more than 4.

Abstract: A colored coating composition comprising (a) 5 to 60% by weight of a polymer having a carboxyl group and a carboxylate group; (b) 5 to 60% by weight of a polymer having a hydroxyl group and an epoxy group; (c) 0.05 to 20% by weight of a pigment-dispersing agent; and (d) 0.1 to 50% by weight of a pigment; (wherein, each amount formulated of the components (a) to (d) is based on the weight of total solid in the colored coating composition), wherein, an acid total amount AR and a base total amount BR which are derived from said pigment-dispersing agent, and an acid total amount AP and a base total amount BP which are derived from said pigment, suffice the following relations: AR>0.5 BP or BR>0.5 AP, and AR+AP >BR. Thus provided is a solid color coating composition that can meet the requirements of mar resistance, acid resistance, storage stability, and excellent appearance.
