This invention is directed to an aqueous colored coating composition which is applied with a spray device having a fine-orifice nozzle(s), the composition comprising a neutralized acrylic copolymer containing an alkoxysilyl group and a carboxyl group and a coloring pigment.

Aqueous colored coating composition

A coating composition which consists essentially of:

Coating composition

The invention provides an automotive top coating composition, comprising as the main components;: (A) an acrylic polymer prepared by copolymerizing 5 to 40% by weight of an alkoxysilane-containing vinyl monomer which is a compound represented by the formula ##STR1## wherein A is ##STR2## R.sub.1 is a hydrogen atom or a methyl group, R.sub.2 is a bivalent aliphatic saturated hydrocarbon group having 1 to 6 carbon atoms, R.sub.3 and R.sub.4 are the same or different and are each a phenyl group, an alkyl group having 1 to 6 carbon atoms or an alkoxy group having 1 to 10 carbon atoms, R.sub.4 is an alkyl group having 1 to 10 carbon atoms, and n is an integer of 1 to 100, 5 to 50% by weight of a hydroxyl-containing vinyl monomer and 10 to 90% by weight of a vinyl monomer which is copolymerizable with the above vinyl monomers, and (B) an amino resin in an amount of 5 to 50% by weight based on the total amount of resin solids in the coating composition.

A heat-curable resinous coating composition comprising as a binder component

Heat-curable resinous coating composition

A dispersion of fine particles of a gelled polymer obtainable by copolymerizing and crosslinking a vinyl monomer mixture containing at least 0.5% by weight each of at least two vinyl monomers in the presence of a macromonomer A, which has a molecular chain of poly(12-hydroxystearic acid) and has at least about one polymerizable unsaturated double bond per molecule in average, and a macromonomer B, which is a copolymer of an ethylenic unsaturated monomer and has a solubility parameter value of from 7.5 to 9.2 and about 1.0 to about 1.5 in average of polymerizable unsaturated double bonds, in an organic solvent which is capable of dissolving the macromonomers A and B but is substantially incapable of dissolving a polymer from said vinyl monomer mixture; and a curable resin composition comprising a dispersion of fine particles of the above-described gelled polymer, a base resin which is non-compatible with the macromonomer A but is compatible with the macromonomer B and which forms a continuous phase, and at least one crosslinking agent selected from the group consisting of an amino resin and a polyisocyanate compound.
