Embodiments described herein provide a coating composition including an aqueous acrylic/polyurethane dispersion. The aqueous acrylic/polyurethane dispersion is produced from at least one isocyanate component, a polyol mixture, and at least one acrylate solvent. The polyol mixture includes a polyester polyol and at least two different oleo-based polyols. The coating composition exhibits improved chemical resistance without sacrificing other properties, such as hardness and abrasion resistance.

Coating compositions are disclosed that include corrosion resisting particles such that the coating composition can exhibit corrosion resistance properties. Also disclosed are substrates at least partially coated with a coating deposited from such a composition and multi-component composite coatings, wherein at least one coating later is deposited from such a coating composition. Methods and apparatus for making ultrafine solid particles are also disclosed.

Provided are a resin material that is superior in coating appearance and adhesion to substrates and can be used not only under organic solvent-diluted conditions but also under aqueous solvent-diluted conditions; an undercoat agent for an inorganic-material thin film containing the same; and a molded body produced by using the undercoat agent for an inorganic-material thin film. Provided are a (meth)acryloyl group-containing acrylic-modified alkyd resin, an active-energy-ray-curable resin composition containing the same, the undercoat agent for an inorganic-material thin film, and a molded body produced by using the undercoat agent for an inorganic-material thin film.

A photosensitive resin composition comprises a modified polyimide polymer having a chemical structural formula of:

##STR00001##

photosensitive monomers, a bisphenol A epoxy resin, a photo-initiator, and a pigment. The modified polyimide polymer is made by a reaction of a polyimide polymer having a chemical structural formula of:

##STR00002##

and glycidyl methacrylate. The carboxyl group of the polyimide polymer reacts with the epoxy group of glycidyl methacrylate. The polyimide polymer is made by a reaction of dianhydride monomers each having an A group, diamine monomers each having the R group, diamine monomers each having the R.sub.1 group, and diamine monomers each having the R.sub.2 group. The diamine monomer having R group is a diamine compound having R group bonding with the carboxyl group. The diamine monomer having R.sub.1 group is a soft long-chain diamine monomer. R.sub.2 group comprises at least one secondary amine group or tertiary amine group.

The antireflection coating includes a medium refractive index layer on the hard coat layer, and a low refractive index layer on the medium refractive index layer. The underlying layer is a cured product of a hexa- or higher functional urethane acrylate monomer. The hard coat layer is a cured product of a hard coat layer composition containing a polymerizable monomer containing 50% by mass or more of a tri- or lower functional urethane acrylate monomer, silica particles, a silane coupling agent, and a metal chelate compound. The medium refractive index layer is a cured product of a medium refractive index layer composition. The low refractive index layer is a particle-free cured product of a low refractive index layer composition.
